(Study leading to embodiment)
The optical transmission device is configured such that an optical transceiver that connects optical fibers and performs photoelectric conversion can be inserted and removed, and an optical transceiver according to the required transmission capacity is mounted. Optical transceivers are required to be smaller, have lower power consumption, and have a larger capacity, and research and development of optical transceivers that meet these demands is progressing. Additionally, in order to reduce costs and ensure compatibility, MSA (Multi Source Agreement) standards have been established that define the size, pin arrangement, connector shape, etc. of optical transceivers, and there is a growing trend toward multi-vendor adoption. Optical transceivers are provided by many vendors (manufacturers). Therefore, it is necessary for optical transmission devices to enable communication between devices by combining various types of optical transceivers depending on usage, price, etc.

On the other hand, optical transceivers are becoming more complex due to demands for larger capacity, and the interface between the optical transceiver and optical transmission device is also becoming more complex to match the optical transceiver. In particular, before starting operation, it is necessary to set parameters for the optical transceiver that optimize the wavelength and characteristics of light. Optical transceivers with speeds of several Gbps can be operated with simple settings, but optical transceivers with speeds exceeding several tens of Gbps require complicated individual adjustments. Furthermore, as mentioned above, many vendors provide optical transceivers, so differences among vendors must also be taken into consideration. For this reason, it is becoming difficult to control optical transceivers due to increased capacity and multi-vendor technology.

Therefore, a method can be considered in which a control program tailored to the optical transceiver is introduced into the optical transmission device. By executing this control program, it becomes possible to perform optimal settings for the optical transceiver. However, since it is difficult to manufacture a control program compatible with all optical transceivers in terms of cost and time, the control program must be compatible with a specific optical transceiver. Then, when a new optical transceiver is installed in the optical transmission device, the control program must be updated according to the new optical transceiver.

Here, in mission-critical systems that require high reliability, such as carrier networks and data center networks, it is necessary to suppress service outages as much as possible. Therefore, in related optical transmission devices, a problem arises in that the control program must be updated while the system continues to operate. That is, in the related technology, when the control program is updated, it is necessary to restart the optical transmission device, so that the service is temporarily stopped. In optical transmission equipment that has optical transceivers installed on multiple ports, restarting the equipment to support a new optical transceiver installed on one port should be avoided as this will affect other services. .

Therefore, in the following embodiments, it is possible to update the control program corresponding to the optical transceiver without restarting the optical transmission device.

FIG. 6 shows an example of the operation of the optical transmission system according to this embodiment. As shown in FIG. 6, first, the optical transceiver 150 stops communication (S101). That is, an operator operating the optical transmission device 100 inputs a shutdown command to the port of the optical transceiver 150 to be stopped. Then, the management unit 111 of the optical transmission device 100 instructs the optical transceiver 150 of the corresponding port to stop communication in response to the input shutdown command. The optical control unit 151 of the optical transceiver 150 controls the optical transmitting/receiving unit 152 to stop communication according to instructions from the management unit 111.

Subsequently, the optical transmission device 100 stops the control program for the optical transceiver 150 (S102). That is, the management unit 111 of the optical transmission device 100 stops the communication of the optical transceiver 150 according to the input command, and also stops the control program in the control program storage area 122. At this time, the management unit 111 sets exclusion for the control program (executes exclusive control). By setting exclusion, the control program cannot be accessed from each section or program of the optical transmission device 100.

Subsequently, the optical transceiver 150 is mounted on the optical transmission device 100 (S103). That is, the old optical transceiver 150 is removed from the port of the optical transmission device 100, and the new optical transceiver 150 is inserted. Then, the optical transmission device 100 acquires the identification information of the optical transceiver 150 (S104). That is, when the identification unit 112 of the optical transmission device 100 detects that the optical transceiver 150 is mounted, it acquires the identification information of the optical transceiver 150 by reading the identification information written in the mounted optical transceiver 150. do. Note that the optical control section 151 of the optical transceiver 150 may notify the identification section 112 of the identification information.

Subsequently, the optical transmission device 100 requests a control program for the optical transceiver 150 from the management device 200 (S105). That is, upon acquiring the identification information of the new optical transceiver 150, the acquisition unit 113 of the optical transceiver 150 transmits a control program request (acquisition request) including the acquired identification information to the management device 200.

Subsequently, the optical transmission device 100 acquires the control program for the optical transceiver 150 from the management device 200 (S106). That is, when the program management unit 210 of the management device 200 receives a control program acquisition request from the optical transmission device 100, it refers to the control program table 221 of the storage unit 220 and identifies the control program corresponding to the requested identification information. Then, the specified control program is transmitted to the optical transmission device 100. Then, the acquisition unit 113 of the optical transmission device 100 receives the control program corresponding to the identification information of the optical transceiver 150 from the management device 200.

Subsequently, the optical transmission device 100 updates the control program of the optical transceiver 150 (S107). That is, upon acquiring the control program corresponding to the optical transceiver 150 from the management device 200, the updating unit 114 of the optical transmission device 100 updates (overwrites) the control program storage area 122 of the storage unit 120 with the acquired control program. .

Subsequently, the optical transmission device 100 starts the control program for the optical transceiver 150 (S108). That is, when the control program is updated, the management unit 111 of the optical transmission device 100 starts (executes) the updated control program. At this time, the management unit 111 releases the exclusion of the control program in the control program storage area 122 (executes exclusive control release). By releasing the exclusion, it becomes accessible from each part of the optical transmission device 100 and each program.

Next, the optical transmission device 100 performs settings necessary for starting communication on the optical transceiver 150 (S109). That is, the setting unit 115 of the optical transmission device 100 instructs the optical transceiver 150 to set the optical wavelength, etc. according to the updated control program. The optical control unit 151 of the optical transceiver 150 sets the optical wavelength and the like for the optical transmitting/receiving unit 152 according to instructions from the setting unit 115.

Subsequently, the optical transceiver 150 starts communication based on the settings (S110). That is, an operator operating the optical transmission device 100 inputs a no shutdown command to the port of the optical transceiver 150 that performs communication. Then, in response to the input no shutdown command, the management unit 111 instructs the optical transceiver 150 of the corresponding port to start communication. The optical controller 151 of the optical transceiver 150 controls the optical transceiver 152 to start communication according to instructions from the manager 111.

When communication of the optical transceiver 150 starts, the monitoring unit 116 of the optical transmission device 100 periodically acquires operational information from the optical control unit 151 of the optical transceiver 150 according to the updated control program, and uses the acquired operational information. The management device 200 is notified. Note that the monitoring unit 116 may transmit the operation information to the management device 200 in response to a request from the management device 200.

By stopping the operation of the optical transceiver and updating the control program when a new optical transceiver is installed (connected), it is possible to operate with a control program compatible with the new optical transceiver without stopping the service. Since the optical transceiver control program is independent from programs that control other functions, the control program can be updated without restarting the optical transmission device. Furthermore, by acquiring and updating different control programs depending on the type of optical transceiver, it is possible to appropriately control the installed optical transceiver.

In addition, variations in transmission capacity and communication standards are increasing, and the number of optical transceiver vendors is also increasing, making it difficult to store many control programs compatible with all optical transceivers in optical transmission equipment. It is. Therefore, in this embodiment, by storing a plurality of control programs for each optical transceiver in a separate device different from the optical transmission device, it is possible to suppress an increase in the storage capacity of the optical transmission device. In addition, since multiple optical transmission devices and other devices exist in the same control network and can communicate with each other, it is possible to send a control program from one separate device to multiple optical transmission devices, and the control program Updates and management can be made more efficient.
