JP6358396B2 - COMMUNICATION PROCESSING DEVICE, IDENTIFICATION INFORMATION GENERATION METHOD, AND IDENTIFICATION INFORMATION GENERATION PROGRAM - Google Patents

Description

  The present invention relates to a communication processing device, an identification information generation method, and an identification information generation program.

According to the Ethernet fabric, a plurality of switches can be operated as one virtual switch by linking a plurality of mutually connected switches. FIG. 1 shows an example of a network in which an Ethernet fabric is introduced (hereinafter referred to as a fabric network). A fabric ID (IDentification information) for identifying the fabric network is allocated to the fabric network. Each switch definitive in the fabric network is allocated an ID for identifying the switch and network settings (e.g., setting of the VLAN (Virtual Local Area Network)) is applied.

  The following conventional techniques exist for assigning IDs to devices in a network. Specifically, the fabric device in the fabric system transmits an allocation signal for each port to which another fabric device is connected. The fabric device that has received the assignment signal determines the identifier of the own fabric device from the assignment signal.

  However, this technique has restrictions on the network configuration, for example, on the assumption that a plurality of fabric devices are connected in a three-stage configuration. In addition, the above-described conventional technology and other conventional technologies do not pay attention to ID allocation particularly when a plurality of switches are exchanged at once.

  FIG. 2 shows the fabric network 1 in the present embodiment. The fabric network 1 includes switches 11 to 14. The fabric ID “f1” is assigned to the fabric network 1. The switches 11 to 14 execute packet relay processing in cooperation with each other. In FIG. 2, the number of switches is four, but the number is not limited.

  Optional components are attached to each switch and connected to the server via the optional components. The optional component is, for example, an SFP (Small Form Factor Pluggable) + module, a 10 GBASE-CR cable, a 40 GBASE-CR 4 cable, or the like. In the example of FIG. 2, optional components 401 and 402 are attached to the switch 14. The switch 14 is connected to the server 304 via an optional component 401, and the switch 14 is connected to the server 404 via an optional component 402. Similarly to the switch 14, the switches 11 to 13 are attached with optional components and connected to the server via the optional components.

  FIG. 3 shows a hardware configuration diagram of the switch. In the example of FIG. 3, the switch includes optional components 151 and 152, a CPU (Central Processing Unit) 153, a memory 154, and a bus 155. The optional component 151 has a storage unit 1511, and the optional component 152 has a storage unit 1521. The storage units 1511 and 1521 are, for example, EEPROM (Electrically Erasable Programmable Read-Only Memory), information unique to the optional component (for example, serial number; hereinafter referred to as unique data), information set by the user, etc. Called user-specified data). In FIG. 3, the number of optional parts is 2, but the number is not limited. Further, the switch has hardware other than the hardware shown in FIG. 3, but the description is omitted because it is not related to the main part of the present embodiment.

  Firmware for executing the processing of the present embodiment is stored in, for example, a ROM (Read Only Memory) or the like, and is executed by the CPU 153 to realize various functions shown in FIG. FIG. 4 shows a functional block diagram of the switch. The switch includes a communication unit 181, a data storage unit 182, a connection destination data storage unit 183, an acquisition unit 184, a generation unit 185, and an application unit 186.

  The communication unit 181 communicates with other switches and servers, and stores received data in the data storage unit 182. The acquisition unit 184 acquires the data stored in the storage area of the optional component (for example, the storage unit 1511 of the optional component 151) and the data stored in the connection destination data storage unit 183, and sends the acquired data to the generation unit 185. Output. The generation unit 185 performs processing based on the data received from the acquisition unit 184 and outputs the processing result to the communication unit 181 and the application unit 186. The application unit 186 executes processing based on the data stored in the data storage unit 182 and the processing result received from the generation unit 185.

  Next, configuration sharing and application in the fabric network 1 will be briefly described with reference to FIGS. 5 and 6.

  The sharing and application of settings when the fabric network 1 is constructed will be described with reference to FIG. The administrator's terminal receives input of settings to be applied to the switches 11 to 14 from the administrator. The administrator's terminal transmits setting data including settings to be applied to the switches 11 to 14 to the switch 11 that is a representative switch. The switch 11, which is a representative switch, transmits setting data to each of the switches 12 to 14. Here, setting data including settings for the switches 11 to 14 is transmitted to each of the switches 12 to 14 so that all the switches in the fabric network 1 can share the settings. Each switch specifies a setting to be applied to the own switch based on the ID of the own switch, and applies the setting to the own switch. In this way, the administrator can apply settings to each switch from the representative switch.

  Application of the setting at the time of switch replacement will be described with reference to FIG. When the switch is exchanged, the setting data held by the representative switch is transmitted to the new switch. In the example of FIG. 6, the switch 14 is replaced with a new switch, and settings for all switches are transmitted from the representative switch 11 to the switch 14. The new switch 14 identifies the setting to be applied to the switch 14 from the received setting data based on the ID of the own switch, and applies the identified setting to the switch 14.

  Next, the operation of the switch in the fabric network 1 will be described in more detail with reference to FIGS. 7 to 10B. First, processing executed by the switch when the fabric network 1 is constructed will be described. Here, it is assumed that the data storage unit 182 of each switch is in an initial state, and the ID and setting are not stored.

  First, an administrator attaches an optional component to each switch in the fabric network 1 and turns on the power. Then, each switch is activated (FIG. 7: Step S1). In FIG. 7, an ellipse figure represents an administrator's work.

  Each switch executes a first ID generation process (step S3). The first ID generation process will be described with reference to FIG.

  First, the acquisition unit 184 acquires at least one of unique data and user-specified data from the storage unit 1511 of the option component 151 and the storage unit 1521 of the option component 152 by, for example, I2C (Inter-Integrated Circuit) (FIG. 8). : Step S21). The acquisition unit 184 outputs the acquired data to the generation unit 185.

  The generation unit 185 generates a first ID from data received from the acquisition unit 184 according to a predetermined algorithm (for example, a hash function) (step S23), and outputs the first ID to the application unit 186 and the communication unit 181. Then, the process returns to the caller process (FIG. 7).

  Returning to the description of FIG. 7, the administrator connects the switches with a cable, and connects the switch and the server with a cable. In response to this, each switch executes network construction processing (step S5). This process includes, for example, a process for enabling communication to be started between nodes (here, a switch and a server). Since this process is a process that is also performed in a normal Ethernet fabric and is a well-known process, a detailed description thereof will be omitted.

  Each switch executes a second ID generation process (step S7). The second ID generation process will be described with reference to FIG.

  First, the acquisition unit 184 acquires connection destination data from the connection destination data storage unit 183 (FIG. 9: step S31), and outputs the acquired data to the generation unit 185. The connection destination data storage unit 183 is, for example, a MAC (Media Access Control) address table, and the connection destination data is, for example, a MAC address of a connection destination device. However, data other than the MAC address may be used as long as the connection destination can be identified.

  The generation unit 185 generates a second ID from the data received from the acquisition unit 184 according to a predetermined algorithm (for example, a hash function) (step S33), and outputs the second ID to the application unit 186 and the communication unit 181. Then, the process returns to the caller process (FIG. 7).

  Returning to the description of FIG. 7, the communication unit 181 transmits the first ID generated in step S <b> 3 and the second ID generated in step S <b> 7 to other switches (step S <b> 9), and stores them in the data storage unit 182.

  The communication unit 181 receives a packet including the first ID and the second ID of the other switch from the other switch, and stores the packet in the data storage unit 182 (step S11). FIG. 10A shows an example of ID data stored in the data storage unit 182. In the example of FIG. 10A, the switch name, the first ID, and the second ID are stored. The first ID is generated using the algorithm f from at least one of the unique data of the optional part and the user-specified data. The second ID is generated from the connection destination data using the algorithm g. Each switch can acquire the switch name of the own switch in advance from the storage area in the own switch. Each switch can acquire the switch name of the other switch from, for example, a packet received from the other switch.

  And the communication part 181 in a representative switch receives the setting data containing the setting of each switch from an administrator's terminal. And the communication part 181 in a representative switch transmits setting data to another switch (step S13). Since this process is a process executed only by the representative switch, the process of step S13 is indicated by a broken line in FIG.

  The representative switch stores setting data in the data storage unit 182. The communication unit 181 in the switch other than the representative switch receives the setting data and stores it in the data storage unit 182. FIG. 10B shows an example of setting data stored in the data storage unit 182. In the example of FIG. 10B, the switch name and setting are stored. It is assumed that the administrator who operates the terminal knows the switch name of each switch arranged in the fabric network 1 and knows which setting should be applied to which switch.

  Then, the application unit 186 identifies the switch name corresponding to the generated first ID and second ID based on the ID data, and identifies the setting corresponding to the identified switch name, thereby setting the setting to be applied to the own switch. It is specified from the data storage unit 182. Then, the applying unit 186 applies the specified setting to the own switch (step S15). In step S15, for example, processing for setting the VLAN information included in the setting in the port is executed. Then, the process ends.

  If the processing as described above is executed, it is possible to automatically assign an ID to each switch. Therefore, the cost is lower than when assigning an ID to each switch manually. Also, there is no allocation error.

  Next, processing executed when any switch in the fabric network 1 is replaced will be described with reference to FIGS. 11 to 13.

  First, an administrator attaches optional parts to a new switch (hereinafter referred to as a new switch) to be introduced by replacement, and turns on the power. Then, the new switch is activated (FIG. 11: Step S41). In FIG. 11, an ellipse figure represents an administrator's work.

  The new switch executes the first ID generation process (step S43). The first ID generation process is as described with reference to FIG.

  The administrator connects the new switch and the existing switch by a cable, and connects the new switch and the server by a cable. In response to this, the new switch executes network construction processing (step S45).

  The new switch executes the second ID generation process (step S47). The second ID generation process is as already described with reference to FIG.

  The communication unit 181 of the new switch acquires setting data and ID data from the representative switch (step S49). More specifically, the communication unit 181 of the new switch transmits an acquisition request for requesting acquisition of setting data and ID data to the representative switch, and the communication unit 181 of the representative switch transmits the setting data and ID as a response to the acquisition request. Send data to the new switch. Then, the new switch application unit 186 stores the received setting data in the data storage unit 182.

  The new switch application unit 186 executes determination processing (step S51). The determination process will be described with reference to FIG.

  First, the application unit 186 determines whether the switch name associated with the same ID as the first ID generated in step S43 is included in the ID data in the data storage unit 182 (FIG. 12: step S61).

  When the switch name associated with the same ID as the generated first ID is included in the ID data in the data storage unit 182 (step S61: Yes route), the process proceeds to step S63. On the other hand, when the switch name associated with the same ID as the generated first ID is not included in the ID data in the data storage unit 182 (step S61: No route), the application unit 186 generates the second ID generated in step S47. It is determined whether the switch name associated with the same ID is included in the ID data in the data storage unit 182 (step S65).

  When the switch name associated with the same ID as the generated second ID is not included in the ID data in the data storage unit 182 (step S65: No route), the process returns to the caller process (FIG. 11). On the other hand, when the switch name associated with the same ID as the generated second ID is included in the ID data in the data storage unit 182 (step S65: Yes route), the application unit 186 generates the generated first ID or the generated ID The setting corresponding to the switch name associated with the second ID (that is, the setting before replacement) is extracted from the data storage unit 182 and applied to the new switch (step S63). Then, the process returns to the caller process (FIG. 11).

  By executing the processing as described above, the same ID as that assigned to the switch before the replacement can be assigned to the switch after the replacement. As a result, the same setting as that before the replacement can be applied to the switch after the replacement.

  Note that ID allocation can be performed manually by an administrator, or a switch that grasps ID allocation can be performed. However, the former method has a problem that it costs work. In addition, the latter method may cause a problem when a plurality of switches are exchanged at one time. For example, as shown in FIG. 13, it is assumed that the switch 13 and the switch 14 are replaced at a time. Assume that the ID that should originally be allocated to the switch 13 is “s3” and the ID that should be allocated to the switch 14 is “s4”. In such a case, the switch that knows the allocation of the ID knows that the replaced switch is the switch with the switch ID “s3” and the switch with the switch ID “s4”. I don't know if should be allocated. Therefore, an incorrect ID may be assigned to a new switch.

  On the other hand, in the present embodiment, the ID is generated from the information on the optional parts mounted on the switch and the information on the devices connected to the switch. IDs are never assigned to switches. Note that when the switch is replaced, optional components may be replaced together, or the connection destination device may be changed. In this case, the ID changes before and after the replacement. However, in this embodiment, two types of IDs are prepared, and if at least one of them matches, the setting is applied, so that it is possible to flexibly cope with a change in ID.

  FIG. 14 shows an example of the administrator's work flow when this embodiment is used. Here, a provisioning function based on user-specified data will be described.

  First, the administrator prepares a switch of the fabric network 1 (FIG. 14: step S71). Here, at least one switch may be prepared as a representative switch.

  For example, the administrator writes user-specified data in the storage unit of the optional parts attached to the switch on a terminal equipped with dedicated writing software or the like (step S73).

  The administrator attaches the optional component in which the user-specified data is written in the operation of Step S73 to the switch, and turns on the switch (Step S75). Here, it is assumed that the administrator determines in advance to which switch each optional component is attached.

  Then, each switch generates a first ID from the user-specified data (step S77). Since Step S77 is not an administrator's work, the work of Step S77 is indicated by a broken line in FIG.

  The administrator instructs the representative switch to input setting data (step S79), and connects a cable between the switches (step S81). Thereby, each switch executes network construction processing, and the representative switch transmits setting data to other switches.

  Then, each switch identifies the setting to be applied to its own switch from the setting data and applies it to its own switch. Then, the operation of the fabric network 1 starts.

  In this case, at least one switch is sufficient at the initial stage, and the work for the switch is only the work for the representative switch (step S79), so the administrator does not have to perform the setting work for each switch. . Therefore, if the administrator installs the optional part in which user-specified data is written without error and stores the setting data in the representative switch, the setting is automatically completed by simply connecting the cable to the switch.

  Although the embodiment of the present technology has been described above, the present invention is not limited to this. For example, for the processing flow, as long as the processing result does not change, the order of the steps may be changed, or a plurality of steps may be executed in parallel.

  Further, the functional block diagram is an example, and may not match the program module configuration.

  Alternatively, one ID may be generated using both the unique data of the optional component or the user-specified data and the connection destination data.

  Further, the ID data and the setting data may be integrated, and the setting may be directly specified from the first ID and the second ID.

  The server described above is a computer device, and as shown in FIG. 15, a display controller 2507 connected to a memory 2501, a CPU 2503, a hard disk drive (HDD) 2505, and a display device 2509. A drive device 2513 for the removable disk 2511, an input device 2515, and a communication control unit 2517 for connecting to a network are connected by a bus 2519. An operating system (OS) and an application program for executing the processing in this embodiment are stored in the HDD 2505, and are read from the HDD 2505 to the memory 2501 when executed by the CPU 2503. The CPU 2503 controls the display control unit 2507, the communication control unit 2517, and the drive device 2513 according to the processing content of the application program, and performs a predetermined operation. Further, data in the middle of processing is mainly stored in the memory 2501, but may be stored in the HDD 2505. In an embodiment of the present technology, an application program for performing the above-described processing is stored in a computer-readable removable disk 2511 and distributed, and installed from the drive device 2513 to the HDD 2505. In some cases, the HDD 2505 may be installed via a network such as the Internet and the communication control unit 2517. Such a computer apparatus realizes various functions as described above by organically cooperating hardware such as the CPU 2503 and the memory 2501 described above and programs such as the OS and application programs. .
