JP7523484B2 - Network Management Device - Google Patents

Description

The present invention relates to a network management device that detects and responds to network communication failures that occur in any of multiple rooms in a facility where network communication is carried out in multiple rooms.

There are various facilities that have multiple rooms. These include public facilities, offices, factories, and lodging facilities such as hotels. In such facilities, multiple rooms are provided, and each room is used by a user. In such facilities, each room is equipped with facilities that allow network communication such as the Internet.

For example, each room is equipped with an access point for wired or wireless network communications. Some rooms are equipped with so-called Wi-Fi access points, while others are equipped with jacks for wired connection cables. Each room user connects their own information terminal, such as a personal computer, tablet terminal, or smartphone terminal, to the access point to connect to a network such as the Internet.

In facilities such as hotels, there is a server that connects the network communication access points in each room to an external network line. This server allows the information terminals connected in each room to communicate with networks such as the Internet.

The room users use information terminals such as network-connected computers in their rooms for a variety of purposes. They use network-connected computers for work, to send e-mails and chat, and to enjoy streaming movies and music.

Network communication uses network bandwidth when an information terminal communicates with a network line. For example, when connected to a network for work purposes, a large or small network bandwidth may be used depending on the work being done.

When it comes to email and chat, the network bandwidth used is often small. On the other hand, streaming movies and music, and downloading applications often use large amounts of network bandwidth.

There are many different types and modes of network communications that room users engage in, and these differ depending on the user's characteristics, purpose, and time. However, there is an upper limit to the network bandwidth between the facility's server and external network lines. If the combined bandwidth of network communications in multiple rooms exceeds this limit, network communications will no longer be possible. Alternatively, approaching the limit can result in a problem of reduced network communication speed and capacity.

At the same time, facilities need to satisfy the users of their rooms. It is undesirable to cause dissatisfaction among users due to slower or less powerful network communications or even outages. For example, in an office, this could significantly reduce the work efficiency of employees and workers. Or, in a hotel or other lodging facility, there is a concern that this could reduce guest satisfaction and lead to complaints from guests.

Technologies have been proposed to address the problems caused by bandwidth usage in network communications (see, for example, Patent Document 1 and Patent Document 2).

JP 2017-152780 A JP 2015-66699 A

Patent Document 1 discloses a control technique in which a statistical information processing means acquires statistical information on mid-communication disconnections caused by user terminals during communication using an application protocol, calculates a user dissatisfaction level for each application protocol based on the statistical information, and manages a pacing threshold corresponding to the user dissatisfaction level for each application protocol. A call processing means determines a pacing threshold for each application protocol such that communication traffic to the user terminal does not exceed a predetermined bandwidth upper limit and the user dissatisfaction level for each application protocol matches, and executes pacing processing so that the communication traffic for each application protocol falls below the determined pacing threshold.

Patent document 2 discloses a bandwidth control system that counts the number of users using an application by referring to the bandwidth usage status, and counts the number of users of the application that is subject to bandwidth restriction in order of the number of users. If the upper limit value of the application that is subject to slowdown control is equal to or less than the value obtained by subtracting the total value of the bandwidth used from the available bandwidth, the target bandwidth of the user terminal is set to the upper limit value/number of users. If the bandwidth used by the user terminal is greater than the target bandwidth, the down width of the user terminal is set to the down width of the application/number of users, and the control bandwidth of the user terminal is set to the value obtained by subtracting the down width of the user terminal from the control bandwidth of the user terminal.

Patent Document 1 discloses a technology for controlling communication bandwidth to meet user satisfaction. However, Patent Document 1 only considers securing bandwidth for specific users, and does not address various issues in multiple rooms while dealing with them individually, and does not balance the bandwidth with the network bandwidth of the entire facility.

In particular, it does not address the issue of network bandwidth caused by the way network communications are used in multiple rooms.

Patent document 2 discloses a system that controls bandwidth based on the relationship between the total bandwidth usage of users and the overall network bandwidth.

However, it only looks at the total bandwidth of users, and does not look at how users are using it to detect problems. In addition, it only controls users' bandwidth usage, and does not disclose how to deal with problematic users or their problematic usage. It also does not disclose that it provides support for the management side that manages the servers to identify problems.

In facilities with multiple rooms, various aspects can occur in the use of network communications by users of the rooms. Particularly in lodging facilities such as hotels, multiple users with completely different attributes and no relationship to each other use the rooms. These users use network communications for their own convenience or discretion. At such times, a user in one room may end up using a large amount of network communications bandwidth. Or a user in another room may use multiple sessions in network communications. Or there may be a user with malicious intent who causes network failures.

If such problematic network communications are used in any of the rooms, the facility manager must monitor and respond. However, there is a problem of not knowing what kind of problem has occurred or how to respond to it. In particular, facility managers are managers of the facility itself (for example, in the case of a hotel, the hotel itself, or in the case of a public facility, the intended use of the facility), and are often not professionals in network communications.

For this reason, even if problematic use in one of the rooms causes network communication problems throughout the facility (such as slow speeds, reduced capacity, and communication failures), it can be difficult for administrators to respond. If it is difficult to respond, this can lead to growing dissatisfaction among users, which could have a negative impact on the reputation of the entire facility.

In addition, if the administrator is unable to handle the problem, they will have to request a specialized network management company to handle the problem, which can lead to a long time until recovery. If recovery takes a long time, this can lead to increased dissatisfaction among users, which can be a negative for the facility.

As described above, conventional technology has the problem of being unable to detect problematic use by users, monitor such detection, or respond to it. These problems can lead to reduced benefits for users. There is also the problem of the facility's evaluation being affected.

In view of these problems, the present invention aims to provide a network management device that can detect problematic usage by users, confirm the details of the problematic usage, and resolve the problematic usage.

In view of the above-mentioned problems, the present invention provides a network management device in a facility having a plurality of rooms, the network management device including: a problem detection unit that detects problematic use of network communications in the rooms;
A display unit that visualizes and displays the question usage;
A solution processing unit that executes a solution process for the problem specification;
a control unit that controls the problem detection unit, the display unit, and the solution processing unit,
In each of the plurality of rooms, an information terminal can be communicatively connected to a network line;
The problem use is,
"Bandwidth Occupancy" refers to network communications in a room occupying a bandwidth greater than a certain value.
"Session Occupancy" refers to the establishment of a certain number of sessions or more in network communications in a room, and "Loop Connection" refers to the establishment of a loop connection in the network communications in the room.
At least one of
the information terminal is connected for communication with the network line via the network connection device,
The problem detection unit detects a problem in use of network communication in the information terminal via the network connection device,
each of the plurality of rooms is provided with a network connection device that enables a communication connection between an information terminal and a network line;
The display unit is viewable by a manager of the facility and is capable of displaying the bandwidth occupancy, the session occupancy, the loop connection, and the room numbers in which these are occurring .

The network management device of the present invention can detect problematic use of network communications by users in multiple rooms. Being able to monitor the results of the detection of problematic use makes network management easier for administrators. In particular, being able to grasp problematic use makes it possible for even administrators with little specialized knowledge of networks to manage the network.

In addition, by automatically responding to problematic usage, it is possible to prevent disruptions to network communications throughout the facility. This also has the advantage that problems can be prevented without waiting for assistance from external experts, ensuring that users can continue to receive the benefits.

In addition, by issuing warnings to users who have used problems as necessary, it is possible to reduce users' use of problems. Furthermore, by combining management and warnings on the administrator's side, it is possible to secure evidence of problem use. This also has benefits for the facility.

The following describes an embodiment of the present invention with reference to the drawings.

(Analysis by the inventor)
The inventor's analysis of problematic usage in a lodging facility will be described as an example of a facility. The lodging facility has multiple rooms, which are used by unspecified guests. In this case, a connection device that is an access point for network communication such as a wired LAN or a wireless LAN (WiFi) is installed in the room.

Guests can connect to this access point to enable network communication on their information devices, such as computers and smartphones. They can use the devices for work, to send emails and chat, or to use streaming services for video and music.

Each room is equipped with an access point connection device, which is network-connected to a server installed in the accommodation facility. The server is connected to an external Internet line, and these connections enable network communication in each room.

Here, a maximum bandwidth is set for the connection between the server and an external Internet line. The maximum bandwidth is set taking into consideration use within the accommodation facility. The speed and capacity of network communication is determined by the relationship between the usage status of network communication in each room and the maximum bandwidth.

Many guests will be using the network for work or leisure. Accommodation facilities set maximum bandwidth and network capacity with this use in mind. For this reason, network communication problems are unlikely to occur in accommodation facilities under normal circumstances (except in unforeseen circumstances such as breakdowns).

However, some guests may engage in problematic use of network communications. Figure 1 is a schematic diagram summarizing problematic use. Figure 1 shows the state of network communications in each of the accommodation facility's rooms. In each of the rooms, guests are connected to Wi-Fi and using network communications.

In Figure 1, the guests in rooms 301, 202, and 201 are using network communications properly. This is within the normal expected range and there are no problems.

On the other hand, different types of problematic usage are occurring in rooms 401, 402, and 302. Problematic usage is usage that has a negative impact on the speed, capacity, and operation of network communications throughout the facility. When problematic usage occurs in any of the rooms, it can exceed the maximum bandwidth set by the facility, making network communications impossible in other rooms or causing network communications to deteriorate. Or network communications can become difficult for reasons other than bandwidth restrictions.

This can be a problem for the entire facility, as well as for other room occupants (other guests). In some cases, it can even result in a complaint being filed against the facility.

Problem usage may involve network communications that establish multiple P2P sessions, such as the problem usage in Room 401. This occurs when a user in Room 401 downloads and uploads to and from multiple servers through multiple sessions.

A large number of sessions are being established in room 401, i.e. "session occupancy." This type of session occupancy is having a negative impact on network communications. It can make network communications in other rooms difficult and can cause errors throughout the facility.

Session domination is a problematic use that causes network communication problems for the facility.

In another case, in Room 402, high-volume network communications are taking place, resulting in "bandwidth occupancy," where the bandwidth is monopolized. When bandwidth occupancy occurs, problems arise such as slower network communications speeds and reduced communication capabilities in other rooms due to the facility-wide bandwidth cap.

Bandwidth occupancy is also a problematic usage.

In yet another case, a "loop connection" occurred in Room 302, where a cable was inserted into the router in a loop shape, making network communication impossible. A loop connection can have a negative effect on network communication, and in some cases, can lead to problems that prevent network communication throughout the entire facility.

This type of loop connection is also a problematic use. Loop connections are caused by malicious actions by users.

When such problematic use occurs, it can have a negative impact on network communications throughout the facility and in other rooms. It can lead to a decline in the level of network communications, which is one of the services provided by the facility, causing inconvenience to users. It can also lead to complaints from users, which can have a negative impact on the facility as well.

Furthermore, these three types of problematic use are often caused intentionally or maliciously by users who cause problems. If they do so intentionally or maliciously, they may make a complaint to the facility, for example, demanding a discount on lodging fees. This may also affect the reputation of the facility.

On the other hand, facility managers are often not experts in networks, and when problematic usage occurs, they can only grasp the resulting phenomenon of network communication failure, making it difficult to identify the problematic usage that is causing it. It is also difficult to understand and analyze the problematic usage. It is also difficult to identify the room where the problematic usage is occurring. Furthermore, it is difficult to respond to the problematic usage. As mentioned above, this is because managers are not experts in network communications and it is difficult to respond.

For this reason, the facility manager (or the reception desk in the case of a lodging facility) can only receive complaints from the user causing the problem or from other users and request an external expert to deal with the situation.

This type of response means that it takes time to resolve the network communication problem, causing inconvenience to people other than the users who caused the problem. Of course, it also leads to complaints from users who intentionally or maliciously caused the problem.

Currently, when problematic use occurs in a facility, it is difficult for the facility to identify or analyze it, and in most cases, the facility is only able to identify the problematic use after requesting an outside expert to deal with the issue. This means that when problematic use does occur, the facility is unable to respond as a whole, which can lead to increased inconvenience for users and damage to the facility.

The inventors have thus analyzed typical examples of problematic use and the problems associated with not being able to address them, leading to the creation of the present invention. Note that the problematic use described using FIG. 1 is only one example, and is not intended to exclude other examples. Also, although the facility has been described as an accommodation facility and the user as a guest, it is not intended to be limited to these.

(Embodiment 1)

(Overall Overview)
Fig. 2 is a block diagram of a network management device according to the first embodiment of the present invention. Fig. 2 shows a network management device 1 corresponding to a plurality of rooms 200. A facility that includes the plurality of rooms 200 is, for example, an accommodation facility. In an accommodation facility, the rooms 200 are guest rooms. The users are guests staying at the facility.

In the case of guests, the room is used by an unspecified number of guests on an unspecified number of days in various ways. The room 200 is equipped with a network connection device 202. The network connection device 202 includes devices such as a router and a wireless network. The network connection device 202 realizes a communication connection between the information terminal 220 and the network line 210, either wired or wireless.

The information terminal 220 may be provided in the room 200, or may belong to the user and be brought into the room 200 by the user. The information terminal 220 is a device capable of communicating via a network line, such as a personal computer, a laptop computer, a tablet terminal, a smartphone, or a mobile information terminal.

In the living room 200, the user can connect the information terminal 220 to the network line 220 to work, send e-mails or chat, enjoy music or video streaming, or surf the web. In accommodation facilities, the living room 200 is equipped with a wireless communication connection such as Wi-Fi. The user can connect the information terminal 220 to this and use it for various purposes.

Network lines 210 are connected to multiple rooms 200 together, and these network lines 210 are connected to a network line outside the facility. This allows a network communication connection between the facility and the outside, and allows users of the rooms 200 to use network communication using information terminals 220.

The network management device 1 manages network communications in a facility that has multiple rooms 200. To manage network communications, the network management device 1 is network-connected to the facility's network line 210. The network management device 1 may be constructed inside a server that is connected to the facility's network line 210, or may be constructed separately from this.

The network management device 1 comprises a problem detection unit 2, a display unit 3, a solution processing unit 4, and a control unit 5. These elements may be provided inside the server described above, or only some of them may be provided on the server. Furthermore, these elements may be constructed as an integrated unit, or some of the elements may be constructed as separate units. As described below, the display unit 3 may be realized by a computer screen at the reception desk, management department, reception desk, etc. of the facility.

The problem detection unit 2 detects problematic use of network communications in the living room 200. The network line 210 is connected to each of the living rooms 220, and the problem detection unit 2 is connected to the same. Therefore, it is possible to determine how a user in the living room 200 is using the information terminal 220 after connecting it to the network, based on the bandwidth used and the state of packets. By grasping the usage state and making a judgment based on that, problematic usage can be detected.

Here, problematic usage includes at least one of the following: "bandwidth occupancy" in which the network communication in room 200 occupies a bandwidth equal to or greater than a predetermined value; "session occupancy" in which the network communication in room 200 establishes a number of sessions equal to or greater than a predetermined number; and "loop connection" in which the network connection in room 200 is looped.

Please note that these are just examples and include other problematic uses.

The display unit 3 can visualize and display the problem usage. The display unit 3 may be provided in the network management device 1, and the manager or the like may be able to view this display unit 3. Alternatively, if the facility is an accommodation facility, the display screen of a computer at the reception may realize the display unit 3. Alternatively, the manager's computer or a management monitor may implement the display unit 3.

The display unit 3 displays the content and type of problem use so that it can be understood. For example, if the problem use is "session occupancy", it displays the fact that it is session occupancy using text, an image, etc. It also displays which room 200 the problem use is occurring in. For example, it explicitly displays that "session occupancy" is occurring in room 401 (one of the rooms 200) as shown in Figure 2.

By displaying this information on the display unit 3, the facility manager can easily and reliably identify problematic usage and the room in which it is occurring.

The solution processing unit 4 executes a solution process corresponding to the problem use. The network management device 1 of the present invention not only detects the problem use, but also automatically solves the problem use. The solution processing unit 4 solves the problem use.

This solution process allows the facility manager to not only understand that a problematic use has occurred that could cause a network communication failure, the room 200 in which the problem occurred, and the details of the problematic use, but also to receive a solution to the problem. This allows the manager to provide an automatic response when a network communication failure occurs, unlike in the past when the manager could not determine the cause or how to deal with the problem. Furthermore, the manager does not need to be knowledgeable about network communications to determine the cause or take action, and there is no need to request an external manager.

This allows problems to be resolved quickly, and of course the costs involved in resolving them can be significantly reduced.

As a result, network management at the facility can be simplified and the reliability of the facility can be improved. Users will also be less susceptible to network communication problems caused by problematic use by users in other rooms. Even if they do experience problems, they can be resolved more quickly, reducing the inconvenience.

In addition, complaints from users to facilities will decrease, increasing trust in the overall operation of the facility. This also benefits facility managers and operators as it reduces the risks associated with complaints, and increases operational efficiency and safety.

The control unit 5 controls the problem detection unit 2, the display unit 3, and the solution processing unit 4. It controls the network management device 1 to control the operation of each element and related operations. It can also control the type and degree of problem usage detected by the problem detection unit 2, the display method on the display unit 3, the solution level in the solution processing unit 4, etc.

Such control by the control unit 5 can increase the flexibility of the operation and functions of the network management device 1. It can also realize a network management device 1 that is suited to the type, size, characteristics, etc. of the facility or room 200.

Next, we'll explain the details of each part and the variations.

(facility)
Fig. 3 is a schematic diagram of a facility in the first embodiment of the present invention. The facility 300 is a facility that includes the room 200 described in Fig. 2 and the like. As shown in Fig. 3, the facility 300 also includes a network management device 1. Note that part or all of the network management device 1 may be physically located outside the facility 300. Fig. 3 conceptually illustrates the network management device 1 that manages network communications in the facility 300.

Here, the facility 300 is at least one of an accommodation facility, an office, a public facility, a factory, a business site, a distribution center, etc. This is because these facilities have multiple rooms 200, and network communication is carried out in each room 200.

When the facility 300 is an accommodation facility, the room 200 is the room 200 of the accommodation facility. The user is a guest, and the guest connects the information terminal 220 to the network line 210 via the network connection device 202. This allows the guest to use network communication.

Each of the rooms 200 is equipped with a network connection device 202 that enables a communication connection between the information terminal 220 and the network line 210. The network connection device 202 has a wired or wireless connection function. For example, it is a WiFi access point. Alternatively, it is a wired cable jack.

These network connection devices 202 are connected to the network line 210. This connection enables the information terminal 220 connected to the network connection device 202 to establish a network communication connection with the network line 210.

In addition, each of the network connection devices 202 is network-connected to the problem detection unit 2. Being network-connected to the problem detection unit 2 makes it possible to detect problematic use of network communication via the network connection devices 202.

(Problem detection section)

The problem detection unit 2 detects problematic use in network communication in the room 200. Problematic use is use in which the state of network communication in the room 200 adversely affects network communication throughout the facility 300 or adversely affects network use in other rooms 200.

Problematic use may occur unconsciously by the occupant of room 200, or it may occur maliciously by the occupant.

Figure 4 is a schematic diagram illustrating problematic use in a facility 300 in embodiment 1 of the present invention. The facility 300 is equipped with multiple rooms 200, and users use network communications in each of the multiple rooms 200. The rooms 200 include room 401, room 301, etc. In some rooms 200, network communications are being used appropriately and without problems, while in other rooms 200, problematic use is occurring, either unintentionally or maliciously.

In the case of FIG. 4, problematic usage is occurring in rooms 302, 401, and 402. The problem detection unit 2 can monitor the entire plurality of rooms 200 via the network line 210. As a result, the problem detection unit 2 can detect problematic usage in rooms 302, 401, and 402. Similarly, it can also detect that problematic usage is not occurring in the other rooms 200.

The problem detection unit 2 detects the following problem usage:

(bandwidth occupancy)
5 is a schematic diagram showing bandwidth occupancy in the first embodiment of the present invention, showing a state in which network communications in room 402, one of the rooms 200, occupy a bandwidth equal to or greater than a predetermined value.

For example, in room 402, a user uses an information terminal 220 to connect to a video site and occupy the network communication bandwidth for a long period of time. This may result in other rooms 200 being unable to use network communications. Even if it does not prevent such use, the communication capabilities and communication speed of network communications in the other rooms 200 may be impeded.

This kind of bandwidth monopoly occurs without the user's knowledge or due to malicious intent.

The problem detection unit 2 judges this to be "bandwidth occupancy." This is one form of problematic use, because leaving it as it is would cause harm to users of the facility 300 and other rooms 200.

The problem detection unit 2 can grasp the usage status of the network communication of the rooms 200 by monitoring via the network line 210. It can also grasp the bandwidth in use. The problem detection unit 2 can determine a predetermined value that serves as the standard for bandwidth occupancy based on the relationship between the maximum bandwidth of the entire facility 300 and the number of rooms 200. If the bandwidth in use in a certain room 200 is equal to or greater than the predetermined value, the problem detection unit 2 judges it as "bandwidth occupancy."

As a result, it is possible to detect that "bandwidth occupancy" is occurring in room 402, as in the example in Figure 5.

Furthermore, the display unit 3 explicitly displays the room where the incident occurred, Room 402, and the content of the incident, "bandwidth occupancy." Figure 5 also shows the display by the display unit 3. In Figure 5, "bandwidth occupancy" is shown as an image, but it may also be shown in text.

In addition, since the display unit 3 can be displayed at the fingertips of a manager, etc., the manager can be sure to know when problematic usage has occurred, in which room it has occurred, and what the problematic usage was. For example, such a display can be shown on a computer at the reception of an accommodation facility. This allows the manager to be sure to know problematic usage and prepare for various responses.

(Session Occupancy)
6 is an explanatory diagram for explaining session occupancy in the first embodiment of the present invention. Session occupancy is one aspect of problem use. In Room 401, which is one of the rooms 200, a state in which a predetermined number of sessions or more have been established is shown.

For example, a user in room 401 is downloading videos and the like via a P2P (peer-to-peer) connection. In order to conceal the source of the downloads, the video content is divided into tens of thousands of pieces and placed on the Internet. These tens of thousands of pieces of video content are accessed and tens of thousands of sessions are established. The router device included in the network connection device 202 exceeds its specifications, making network communication in other rooms 200 impossible.

Such problematic usage is referred to as "session occupancy" and can be detected by the problem detection unit 2. In this case, it is occurring in room 401. Of course, while monitoring all rooms 200, it is possible to detect rooms 200 in which such session occupancy is occurring.

The problem detection unit 2 detects the occurrence of session occupancy and the room in which it occurred. It can also detect the time of occurrence.

The problem detection unit 2 outputs the detection result to the display unit 3, which displays it as shown in Figure 6.

The display unit 3 explicitly displays the room where the incident occurred, Room 401, and the content of the incident, "Session Occupancy." Figure 6 also shows the display by the display unit 3. In Figure 6, "Session Occupancy" is shown as an image, but it may also be shown in text.

In addition, since the display unit 3 can be displayed at the administrator's fingertips, the administrator can be sure to know when problematic usage has occurred, in which room it has occurred, and what the problematic usage was. For example, such a display can be shown on a computer at the reception of an accommodation facility. This allows the administrator to be sure to know problematic usage and prepare for various responses.

(Loop connection)
7 is an explanatory diagram for explaining a loop connection in the first embodiment of the present invention. A loop connection is one aspect of problem use. In room 302, which is one of the rooms 200, a user connects a cable to a HUB included in the network connection device 202 so as to create a loop. This type of loop connection causes loop packets to occur in the network line 210. The occurrence of loop packets leads to a problem in which network communication is no longer possible throughout the facility 300.

In other words, when the problem detection unit 2 detects a loop packet in network communication, it can detect that a loop connection has occurred.

Such loop connections are almost always the result of mischief or malice on the part of users. In Figure 7, a user in room 302 maliciously inserted a cable in a loop, causing a loop connection.

For example, a user in room 302 makes a loop connection with the malicious intent of causing trouble to facility 300. If facility 300 is a lodging facility, the user may do this with the malicious intent of damaging the reputation of facility 300 or of filing a complaint to get a discount on the accommodation fee.

The loop connection may cause network communication to be interrupted, making it impossible for other rooms 200 to communicate via the network. This is undesirable for the facility 300, and may lead to a decrease in the reliability of the facility 300.

The problem detection unit 2 monitors the network line 210 and can detect a loop packet in a certain room 200. When this loop packet is detected, the problem detection unit 2 can detect that a loop connection has occurred in that room 200. In FIG. 7, this is room 302.

The problem detection unit 2 detects the fact that a loop connection has occurred and the room in which it occurred. It can also detect the time of occurrence.

The problem detection unit 2 outputs the detection result to the display unit 3, which displays it as shown in Figure 7.

Display unit 3 clearly displays room 302, the room where the incident occurred, and the nature of the incident, "loop connection." Figure 7 also shows the display by display unit 3. Figure 7 shows an image of a "loop connection" and a display of "tampering," which is the assumed cause. These can effectively alert the manager of facility 300.

In addition, since the display unit 3 can be displayed at the administrator's fingertips, the administrator can be sure to know when problematic usage has occurred, in which room it has occurred, and what the problematic usage was. For example, such a display can be shown on a computer at the reception of an accommodation facility. This allows the administrator to be sure to know problematic usage and prepare for various responses.

The problem detection unit 2 can also detect problem uses other than those mentioned above. It detects problem uses in network communications that are possible depending on the characteristics of the facility, etc. In this case, it is also preferable to be able to change or add to the criteria and content of problem use as appropriate.

These changes and additions may be made via the control unit 5.

(Display)
The display unit 3 can be viewed by the manager of the facility 300, and can display the details of problematic usage such as bandwidth occupancy, session occupancy and loop connection, and the room number where the problem is occurring.

For example, the display screen of the manager's computer serves as display unit 3, and these are displayed on this display screen. Or, they are displayed on the display screen of a computer at the reception of the accommodation facility. This is because display unit 3 is installed at the reception.

The display unit 3 may display not only the content of the problem use, but also the solution content and solution results from the solution processing unit 4 described below. This is because being able to visually confirm the solution results increases convenience for the manager. The display unit 3 may also be multiple or be multiple existing display screens (display screens at reception or on the manager's computer). This is because displaying in multiple locations as the display unit 3 allows managers and staff to share information about the occurrence of problem use and the status of its resolution.

The display unit 3 also displays images, text, or other information in a way that attracts the attention of the administrator and makes it easy to understand. In some cases, the display also includes audio. This is because it can reliably inform the administrator of the problem and its solution.

(Resolution Processing Section)
When a problem occurs, the solution processing unit 4 solves the problem. The solution processing unit 4 is connected to the network line 210. This allows a problem occurring in network communication to be solved by a corresponding process for the network communication.

(Solution to Bandwidth Occupancy)
When the problem usage is "bandwidth occupancy", the solution processing unit 4 restricts the bandwidth of the room 200 causing the bandwidth occupancy, as shown in Fig. 8. The room 402 is causing the bandwidth occupancy described in Fig. 4. The bandwidth allowed for room 402 is restricted. This bandwidth restriction reduces the bandwidth used, and resolves the state of bandwidth occupancy.

Figure 8 is a schematic diagram explaining how to resolve bandwidth occupancy in embodiment 1 of the present invention.

The solution processing unit 4 can control communication via the network line 210. In this control, the maximum bandwidth allowed for room 402 can be reduced. This reduces the bandwidth allowed for room 402, which was causing the bandwidth occupancy.

Although limiting the bandwidth in room 402 will reduce convenience for users of room 402, since the users were communicating for long periods of time and in large volumes to video sites, etc., this is not a major problem from the perspective of fairness with users of other rooms 200. Also, there are cases in which bandwidth occupancy occurs maliciously by users, so this is an appropriate solution from this point of view as well.

Users in the other rooms 200 will receive the necessary communication bandwidth, eliminating the inconvenience caused by the bandwidth monopoly in Room 402.

These solutions are carried out in the background without the user's knowledge. Therefore, the problem is resolved without the user who caused the bandwidth occupancy or the users of other rooms 200 who are affected by this noticing. If the user who caused the bandwidth occupancy is malicious, the problem can be dealt with by making it less likely for the malicious user to make a complaint, and the problem can be resolved before inquiries from users of other rooms 200 arise.

The bandwidth restriction may be applied for the period during which the user of Room 402 is using the service, or may be released after a certain period of time has passed. If the same bandwidth occupancy problem occurs after the restriction is released, the solution processing unit 4 will take the same action again.

It is possible to permanently limit the bandwidth of each room 200 or distribute it fairly, but this has the disadvantage that if some rooms 200 are not used, the bandwidth of the remaining rooms 200 will be meaninglessly limited. In addition, it is not possible to flexibly respond to different usage conditions for each room 200.

As a result, if no problematic bandwidth usage occurs, there is no need to standardize distribution and restrictions for each room, but instead, bandwidth can be restricted after problematic usage occurs, allowing for a flexible and safe response.

(Solution to session monopoly)
When the problematic usage is a "session occupancy" occurring in a certain room 200, the network communication of the room 200 where the problem occurred is cut off, as shown in Fig. 9. As explained in Fig. 5 and other figures, the solution processing unit 4 cuts off network communication for room 401 where the session occupancy is occurring. The solution processing unit 4 can control communication via the network line 210, and can use this communication control to cut off communication.

Figure 9 is an explanatory diagram explaining the resolution of session occupancy in embodiment 1 of the present invention.

When the number of sessions is abnormal, limiting the bandwidth is not an effective solution, because many sessions will be established within the limited bandwidth, causing problems with communications in other rooms.

Furthermore, users who are causing session domination often do so with malicious intent or with the conviction that problems will occur. For this reason, leaving it unattended is undesirable for both facility 300 and other users. Furthermore, such malicious users may file a complaint against facility 300 if they use the facility in a problematic way.

For this reason, it is appropriate for the resolution processing unit 4 to perform resolution processing by blocking the network. Since the user also understands that he or she is maliciously or confidently occupying the session, it is considered that the user has no choice but to accept this kind of response.

In addition, if the network is blocked, it will no longer be possible to occupy a similar session, and concerns that inconveniences will reoccupy other users of the rooms 200 will be greatly reduced. The facility 300 will also be able to focus its response solely on the user making the problematic use, reducing the likelihood of receiving complaints or inquiries from other users.

This type of resolution process allows appropriate action to be taken for the facility 300 and the user. Of course, this is done in the background without the user noticing, which is convenient for both the facility and the user.

(Supports loop connections)
If the problem usage is a "loop connection" occurring in a certain room 200, the network communication of the room 200 where the problem occurred is cut off, as shown in Fig. 10. As explained in Fig. 5 and other figures, the solution processing unit 4 cuts off network communication for room 302 where the loop connection is occurring. The solution processing unit 4 can control communication via the network line 210, and can use this communication control to cut off communication.

Figure 10 is an explanatory diagram explaining how to resolve a loop connection in embodiment 1 of the present invention.

If a loop connection has been made maliciously or maliciously, limiting the bandwidth will not be enough to deal with the problem. This is because loop packets will be generated, preventing network communication in other rooms.

As mentioned above, users who create loop connections often do so with malicious or mischievous intent. For this reason, leaving it as it is is not desirable for either facility 300 or other users. Furthermore, such malicious users may file a complaint against facility 300 if they use the facility in a problematic way.

For this reason, it is appropriate for the resolution processing unit 4 to perform resolution processing by shutting down the network. Since the user understands that he or she is making a loop connection maliciously or mischievously, it is likely that the user has no choice but to accept this type of response.

In addition, if the network is cut off, other rooms can still use the network even if the loop connection cannot be resolved by physically plugging in a cable. Facility 300 can also focus its response only on the user with the problem, reducing the possibility of receiving complaints or inquiries from other users.

This type of resolution process allows appropriate action to be taken for the facility 300 and the user. Of course, this is done in the background without the user noticing, which is convenient for both the facility and the user.

As described above, the network management device 1 in embodiment 1 can detect problematic usage and automatically resolve it. This provides convenience to facility users and managers.

(Embodiment 2)

Next, we will explain the second embodiment. In the second embodiment, we will explain other variations.

(Warning section)
Fig. 11 is a block diagram of a network management device according to the second embodiment of the present invention. The network management device 1 in Fig. 11 further includes a warning unit 6. The warning unit 6 issues a warning to the room 200 that has caused the problematic use. In other words, a warning is issued to the user who has caused the problematic use.

By receiving a warning from the warning unit 6, the user who caused the problematic use can understand the fact that they caused it. Furthermore, the detection and resolution process of the problematic use is carried out in the background without the user's knowledge. By issuing a warning, it is possible to notify the non-malicious user who caused the problematic use.

Furthermore, it will let malicious or prank users know that the administrators are aware of the problematic usage. This will encourage users who are causing problematic usage to exercise self-restraint. It can also act as a deterrent in the future. In addition, it will help prevent unreasonable complaints from malicious users.

As shown in FIG. 11, a living room 200 is often equipped with a receiver 201. For example, a room 200 in a lodging facility is installed. The receiver may be a television or a multifunction monitor. These receivers are often connected to a network line 210 via a set-top box or the like. For this reason, communication control of the receiver 201 can be performed from the network management device 1.

Through this communication control, the warning unit 6 displays a warning on the receiver 201.

The warning unit 6 may also display a warning on the information terminal 220 of the room 200 where the problematic use occurred. The information terminal 220 is connected to the network line 210. This connection state is utilized to display the warning.

By displaying a warning on the receiver 201 or the information terminal 220, it is possible to warn users who have engaged in problematic use and to prevent them from making unreasonable complaints. Or, even if an unreasonable complaint is made, it becomes easier to deal with it.

Of course, we will also provide a polite response to users who have issues by notifying them that the problem has been resolved in the background.

The warning may be given using at least one of an image and sound. By giving a warning using these means, it is possible to reliably warn the user who has used the problem while allowing them to understand how the problem was used and how it was resolved.

Figure 12 is a schematic diagram showing a warning display on an information terminal in embodiment 2 of the present invention. It shows a state in which a warning is displayed on an information terminal. The warning clearly indicates that there is a loop connection, bandwidth occupancy, or session occupancy. This makes it possible to notify the user who has engaged in problematic use and ensure that they are informed.

Displaying the information also serves as evidence that problematic use has occurred and that the facility 300 was aware of it. Having evidence makes it possible to respond to unreasonable complaints by users.

In FIG. 12, the information is displayed on the information terminal 220, but it may also be displayed on the receiver 201, or it may be displayed on both.

The warning displayed on at least one of the receiver 201 and the information terminal 220 can be terminated by the user. By making the warning terminating possible, the user can be sure to recognize that he or she has seen the warning. In addition, by processing the warning to be terminating possible, the administrator of the facility 300 can understand that the user has recognized the warning.

In addition, this display and the termination process performed by the user can be saved as evidence, including the time and date. Complaints from users can be handled based on this evidence.

The control unit 5 can store at least one of the occurrence of problematic use, the content of the problematic use, the time when the problematic use occurred, the room number where the problematic use occurred, the time when the warning was issued, the room number where the warning was issued, and the time when the user terminated the warning.

Such storage allows the facility 300 to obtain evidence for subsequent action in the event of problematic use. It can also be used to respond to unreasonable complaints from users who have engaged in problematic use.

As described above, the network management device 1 in embodiment 2 can respond to users who have made problematic use of the device.

The network management device described in the first and second embodiments is an example for explaining the gist of the present invention, and includes modifications and alterations that do not deviate from the gist of the present invention.
