<First embodiment>
The information processing apparatus according to the first embodiment will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating a communication system including a communication device which is an example of an information processing apparatus.
The communication system 100 is configured by connecting a communication device 1a, a communication device 1b, a management server 2, and a control PC 3 via a communication network. The communication device 1a is connected to the management server 2, the control PC 3, and the communication device 1c via the first communication network 40, respectively. The communication device 1a is connected to the communication device 1b via the second communication network 50. The communication device 1b may be connected to another device (not shown) via the third communication network 60. The communication device 1a, the communication device 1b, and the communication device 1c are collectively referred to as the communication device 1. The communication system shown in FIG. 1 is simplified for the sake of explanation, and more devices such as the communication device 1 may be connected. In this embodiment, the communication device 1 is assumed to be a network relay device such as a router, but may be another information processing device.

FIG. 2 is a functional block diagram of the communication device.
The communication device 1 includes a CPU 10, an L2 switch unit 20, and a nonvolatile storage unit 30. Although the communication device 1 has other configurations, the configuration necessary for the description of the present invention is illustrated. The communication device 1 according to the first embodiment has a layer 2 switch function. The CPU 10 has a function of the management information control unit 11 by executing a program. The L2 switch unit 20 may also have the function of the switch control unit 21 by executing a program. The management information control unit 11 and the switch control unit 21 may be configured to include hardware such as a circuit. The CPU 10 includes a volatile storage unit 31.

The management information control unit 11 includes functions of an update management unit 111, a CPU management unit 112 (management information transmission unit, management information acquisition unit), and a recording destination determination unit 113.
The switch control unit 21 includes a function of the frame transfer processing unit 211 and a queue 212.

In the communication device 1 according to the present embodiment, the update management unit 111 detects the start of update of the update target inside the communication device 1.
Further, the recording destination determining unit 113 determines a recording destination device from among a plurality of other devices that are communicatively connected to the own device.
In addition, the CPU management unit 112 transmits the management information of the own device to a recording destination device that temporarily records the management information.
The recording destination determination unit 113 acquires management information from the recording destination device when detecting that the update of the update target has been completed.

  Through such processing, the communication device 1 records the management information in another device so that the management information is not deleted when updating the update target inside the device, and acquires the management information after the update. Even after updating, the management information can be used for processing.

  FIG. 3 is a diagram showing management information such as statistical data, communication protocol data, alarm status (A / S) data, which is data generated or acquired by the communication device 1. Statistical data, communication protocol data, A / S data, and the like are normally recorded in the volatile storage unit 31. Therefore, when the CPU 10 is restarted, the information recorded in the volatile storage unit 31 is deleted. The statistical data is data indicating the performance state of the communication device 1 represented by PMON (Performance Monitoring) information, RMON (Remote network Monitoring) information, and the like. The communication protocol data is data for storing the state of a communication protocol used for ensuring network redundancy, such as information acquired by ERP (Ethernet Ring Protection) or STP (Spanning Tree Protocol). The A / S data is data for confirming a device failure, failure state, device state, and the like.

FIG. 4 is a first diagram showing a processing flow of the communication system.
FIG. 5 is a second diagram showing a processing flow of the communication system.
Next, the processing flow of the communication system will be described in order with reference to FIGS.
First, the management server 2 transmits a firmware update request to the communication device 1a. The update management unit 111 of the communication device 1a receives the firmware update request (step S101). The update management unit 111 detects the start of firmware update based on the reception of the firmware update request (step S102). The update management unit 111 starts a firmware update process (step S103). The update management unit 111 transmits an L2SW_C-plane closing request to the L2 switch unit 20 (step S104). The L2SW_C-plane closing request is a signal that requests the L2 switch unit 20 to stop the control control related to the C-plane. The L2 switch unit 20 receives the L2SW_C-plane blocking request. Then, the frame transfer processing unit 211 stops transmission of data related to the C-plane to be transmitted to the CPU 10 (step S105). The frame transfer processing unit 211 accumulates the data in the queue 212 (step S106). Note that the frame transfer processing unit 211 of the L2 switch unit 20 continues to perform frame transfer processing for communication data packets to be transferred received from other communication devices 1 even after receiving the L2SW_C-plane blocking request. Can do. The update management unit 111 may transmit a blocking request for information other than the L2SW_C-plane blocking request to the L2 switch unit 20. The other information is information such as M-plane. The frame transfer processing unit 211 records information on the C-plane or the like that requires processing in the CPU 10 in the queue 212 based on the blocking request, and stops the transfer to the CPU.

  The update management unit 111 transmits a CPU reset request to the CPU management unit 112 (step S107). Receiving the CPU reset request, the CPU management unit 112 transmits a recording destination search request to the recording destination determination unit 113 (step S108). The recording destination determination unit 113 sends a recording destination search request to the communication device 1c connected via the first communication network 40, the communication device 1b connected via the second communication network 50, and the first communication network. It transmits to control PC3 connected via 40 (step S109). The recording destination determination unit 113 may transmit a recording destination search request to a predetermined device among other devices connected via the communication network, or may be another device connected via the communication network. A recording destination search request may be transmitted to all of them using a technique such as broadcast. The recording destination determination unit 113 receives a search response corresponding to the recording destination search request (step S110). The recording destination determination unit 113 determines a recording destination from other devices based on the search response (step S111). Details of the recording destination determination method will be described later. The recording destination determination unit 113 transmits recording destination information including the network address, device name, other device identification information, storage folder information, and the like, which are information of the device determined as the recording destination, to the CPU management unit 112 (step S112). ).

  The CPU management unit 112 acquires recording destination information. The CPU management unit 112 records the recording destination information in the nonvolatile storage unit 30 (step S113). Further, the CPU management unit 112 reads the management information recorded in the volatile storage unit 31 (step S114). The CPU management unit 112 transmits the management information to the recording destination device indicated by the recording destination information (step S115). For example, in this embodiment, it is assumed that the recording destination device is the management server 2. When receiving the management information, the management server 2 serving as the recording destination device stores the management information in the storage destination folder. The management information recorded in the volatile storage unit 31 by such processing is recorded in the remote management server 2 and only the recording destination information including identification information such as the network address of the management server 2 is stored in a nonvolatile manner. Part 30 is recorded. Therefore, it is not necessary to increase the storage capacity of the high-cost nonvolatile storage unit 30 for recording management information, and the cost can be reduced. Further, since only the recording destination information is recorded only when the update process of the update target is performed, it is impossible to write to the nonvolatile storage unit 30 due to an increase in the number of rewrites to the nonvolatile storage unit 30 with a limited number of rewrites. Can be avoided.

  Next, the CPU management unit 112 transmits a CPU reset response to the update management unit 111 (step S116). Upon receiving the CPU reset response, the update management unit 111 performs known firmware update processing and restart processing (step S117).

  When the restart process is completed and the communication device 1a is restarted, the update management unit 111 in the communication device 1a starts a management information recovery process (step S118). The update management unit 111 outputs a signal instructing the CPU management unit 112 to restore the management information (step S119). When acquiring the signal, the CPU management unit 112 reads the recording destination information from the nonvolatile storage unit 30 (step S120). The CPU management unit 112 transmits a management information acquisition request to the recording destination apparatus based on the recording destination and storage folder information included in the read recording destination information (step S121). The management server 2, which is a recording destination device, reads management information from the storage folder based on the reception of the acquisition request, and transmits it to the communication device 1a. The CPU management unit 112 acquires management information (step S122).

  The CPU management unit 112 confirms the validity of the acquired management information (step S123). For example, the CPU management unit 112 may determine whether it is the data of its own device from information described in statistical data, communication protocol data, A / S data, etc. included in the management information. Alternatively, the presence or absence of data corruption such as CRC (Cyclic Redundancy Check) of management information may be checked. If the CPU management unit 112 determines that the acquired management information is valid, the CPU management unit 112 records the management information in the volatile storage unit 31 (step S124). When recording of the management information in the volatile storage unit 31 is completed, the CPU management unit 112 outputs a management information recovery response to the update management unit 111 (step S125). Upon receiving the management information recovery response, the update management unit 111 outputs L2SW_C-Plane blockage release to the L2 switch unit 20 (step S126). Then, the frame transfer processing unit 211 of the L2 switch unit 20 outputs the information to be transmitted to the CPU 10 accumulated in the queue 212 to the CPU 10 (step S127). As a result, the firmware update processing in the communication device 1a is completed, and the processing shifts to normal communication device 1a.

FIG. 6 is a diagram showing a first recording destination determination table.
FIG. 7 is a diagram showing a second recording destination determination table.
The recording destination determination unit 113 may determine the recording destination device according to the amount of information that can be recorded by the recording destination device. The recording destination determination unit 113 may determine the recording destination device according to the line state of the communication connection line between the recording destination device and the own device.
The recording destination determination table shown in FIG. 6 records storage destination identification information, free capacity, transmission capacity, bit error, and determination result in association with each other. When the recording destination determination unit 113 transmits a recording destination search request in step S109 described above, as a result, the recording destination determination unit 113 receives a search response from each of the management server 2, the control PC 3, the communication device 1b, and the communication device 1c. The search response includes the data free capacity of the storage unit of each candidate storage destination device such as the management server 2, the control PC 3, the communication device 1b, and the communication device 1c, and the lowest communication network connected to each candidate device. The transmission capacity, bit errors per unit time in communication with these candidate devices, and the like are included. The recording destination determination unit 113 generates a recording destination determination table based on information included in these search responses. The recording destination determination unit 113 determines an apparatus to be a recording destination using information in the recording destination determination table. In FIG. 6, each information of the management server 2 is not shown.

The recording destination determination unit 113 is a parameter for determining the recording destination.
Parameter 1: Priority of management information Parameter 2: Data size of management information Parameter 3: Recording destination information Parameter 4: Free space in storage unit of recording destination Parameter 5: Minimum communication network connected to recording destination Parameter 6: Number of bit errors of link connected to recording destination (last 24 hours)
Determine the recording destination in consideration of the above.

Then, the recording destination determination unit 113
(Step S61) Confirmation of priority of management information to be recorded (Step S62) Confirmation of data size of management information to be recorded (Step S63) Retrieval of recording destination (Step S64) Confirmation of free capacity of each candidate device as storage destination Step S65) Confirmation of minimum transmission capacity of link connected between candidate devices (Step S66) Confirmation of number of bit errors of link connected to recording destination (Step S67) Determination of device as recording destination (Step S68) ) Process to send management information to the recording destination.

This recording destination determination process will be described below using more specific values. The priority order of management information to be recorded in the recording destination device may be set by the user.
<Recording destination determination process 1>
Assume that the data amount of each management information at a certain time is the following value.
PMON / RMON data 20Mbyte
Communication protocol data 100Mbyte
A / S data 2Mbyte
Total 122Mbyte
Here, the priority of management information is as follows.
PMON / RMON> communication protocol data> A / S data The recording destination determination unit 113 may create a second recording destination determination table as shown in FIG. The second recording destination determination table associates the identification information of each management information, the priority, and the data amount.

  In the following description, it is assumed that there are three devices that are candidate recording destinations: the control PC 3, the communication device 1b, and the communication device 1c. It is assumed that the memory capacity of the communication device 1b is 100 Mbytes and the memory device 1c has a free capacity of 150 Mbytes. Assume that the control PC 3 is equipped with an HDD and has 2 Gbytes of free space.

  The communication device 1a is wirelessly connected to the communication device 1b with a transmission capacity of 10 Mbps, and is wirelessly connected to the communication device 1c with a transmission capacity of 2 Mbps. It is assumed that the communication device 1a is connected to the control PC 3 with a 100 Mbps LAN cable. In the link between the communication device 1a and the control PC 3, the number of occurrences of bit errors in the past 24 hours is zero. It is assumed that a bit error has occurred twice in the past 24 hours in the link between the communication device 1a and the communication device 1b. It is assumed that a bit error has occurred once in the past 24 hours in the link between the communication device 1a and the communication device 1c.

  When the recording destination determination unit 113 generates the recording destination determination table as shown in FIG. 6, the control PC 3 records all management information in the control PC 3 because the free space has a sufficient link speed compared to other storage destinations. decide. Since the connection between the communication device 1a and the communication device 1b or the communication device 1c is a link in the main signal line through which user traffic flows, the user traffic should basically be transferred with priority. The frame transfer processing unit 211 uses priority control that uses information included in the header of the extended MAC frame used in the 802.1Q VLAN to reduce communication for transmission of management information rather than user traffic. It may be handled as a priority frame.

<Recording destination determination process 2>
Next, another recording destination determination process by the recording destination determination unit 113 will be described. The recording destination determination unit 113 acquires information on the data amount of 200 Mbytes of PMON / RMON data, the data amount of 100 Mbytes of communication protocol data, and the data amount of 20 Mbytes of A / S data. The total data amount of each data is 320 Mbytes.

Here, the priority of each data included in the management information is assumed to be in the following order.
A / S data> PMON / RMON data> communication protocol data Assume that the free space of the memory of the communication device 1b is 200 Mbytes and the free space of the communication device 1c is 150 Mbytes. It is assumed that the control PC 3 is not connected. It is assumed that the communication device 1a is wirelessly connected to the communication device 1b with a transmission capacity of 10 Mbps. Further, it is assumed that the communication device 1a is wirelessly connected to the communication device 1c with a transmission capacity of 2 Mbps. In this case, the recording destination determining unit 113 of the communication device 1a sends the A / S data having the highest priority to the communication device 1b that is connected to the communication device 1b through a link having a large transmission capacity among the connected recording destination candidates. Decide to record. As a result, the free capacity of the communication device 1b is reduced by 20 Mbytes to 180 Mbytes. Next, the recording destination determination unit 113 determines to record 180 Mbytes of PMON / RMON data in the communication device 1b that is in communication connection with a link having a large transmission capacity. As a result, there is no free capacity in the communication device 1b. Next, the recording destination determining unit 113 determines to store the remaining 20 Mbytes of PMON / RMON data in the communication device 1c. In addition, the recording destination determination unit 113 of the communication device 1a determines to record the remaining communication protocol data in the communication device 1c.

<Recording destination determination process 3>
Next, still another recording destination determination process by the recording destination determination unit 113 will be described. The recording destination determination unit 113 acquires the data amount of each data included in the management information. At this time, it is assumed that the PMON / RMON data is 400 Mbytes, the communication protocol data is 200 Mbytes, the A / S data is 20 Mbytes, and the total amount of management information is 620 Mbytes. In addition, the priority of each data included in the management information is as follows.
A / S data> Communication protocol data> PMON / RMON data

  Assume that the free space of the memory of the communication device 1b is 200 Mbytes, and the free space of the communication device 1c is 150 Mbytes. It is assumed that the control PC 3 is not connected. It is assumed that the communication device 1a is connected to the communication device 1b in a wireless connection state of 10 Mbps. It is assumed that the communication device 1a is connected to the communication device 1c in a wireless connection state of 2 Mbps. In this case, the recording destination determination unit 113 determines to record the A / S data with the highest priority in the communication device 1b that is connected for communication. The recording destination determining unit 113 determines to record the communication protocol data having the next highest priority separately for the communication device 1b and the communication device 1c that are connected for communication. Thereby, since the total data amount of A / S data and communication protocol data is 220 Mbytes, the remaining free capacity of the communication device 1 c is 130 Mbytes. However, since the data amount of the PMON / RMON data that finally determines the recording destination is 400 Mby, the PMON / RMON data cannot be recorded in the communication device 1c. In this case, the recording destination determination unit 113 of the communication device 1a outputs an alarm to notify the user that all management information cannot be recorded in the recording destination.

The service normally implemented by software cannot take over the state because the CPU 10 and the memory (DRAM) are reset. However, according to the above-described processing, the communication device 1 can implement ISSU (In Service Software Upgrade) in which the control software update operation is completed while continuing the service without stopping the data transfer.
In addition, as a primary saving destination of management information used by the CPU, another communication device 1 that is connected for communication or another PC 3 that is connected for communication is used. As a result, the capacity of a non-volatile storage unit (non-volatile memory or the like) installed in information processing such as a communication device that performs update of the update target can be reduced, and the cost of the communication device can be reduced.
Further, according to the above-described processing, since the service can be continued for the other communication devices 1 that are in communication connection when the network is redundant, the link down does not occur with the ISSU, and the network switching does not occur. As a result, it is possible to perform an update process for an update target such as firmware of a communication device without causing a frame loss in the entire network.

<Second Embodiment>
In the communication system described above, a device connected by an IP network using an M-Plane signal may be defined as a recording destination. In the first embodiment, a communication device or the like directly connected adjacently is used as a management information recording destination. However, management information may be recorded using a device connected via M-Plane communication as a recording destination as long as it is a device that can be connected via another device using an IP address even if it is not directly connected.

<Third embodiment>
In the third embodiment, an operation when using the Ethernet (registered trademark) _Ring function will be described. A case where the Ethernet (registered trademark) _Ring function defined in the ITU-T recommendation G8032 is used will be described. The Ethernet (registered trademark) _Ring function designates an arbitrary place in the network ring as an RPL (Ring Protection Link) port, and transmits and receives an R-APS (Ring Automatic Protection Switching) control frame. This is a network redundancy function that, when a failure occurs in the ring path, releases the blocking of the RPL port, performs FDB (Filtering Database) flushing, and switches each node network. The FDB flash indicates that the MAC address learned at the link port of the protected Ethernet (registered trademark) ring is removed from the filtering database of the Ethernet (registered trademark) ring node. In a case where this function is realized by processing of the CPU, when the CPU is reset due to firmware update, the communication device directly connected to the communication device having the CPU determines a link failure and switching occurs. For switching, an FDB flash is generated in each device constituting an ERP (Ethernet Ring Protection), so an instantaneous interruption always occurs. Therefore, if the state is restored after the CPU is reset, the path can be switched without causing the path to be switched.

<Fourth embodiment>
In the fourth embodiment, a warm boot operation accompanied by hardware replacement at the time of CPU failure will be described. The warm boot indicates that the OS function is restarted in response to the start-up after the power is turned off to completely erase the memory contents. Hereinafter, an example of hardware replacement at the time of CPU failure will be described as an application example.

  In the processing described in the first embodiment, the communication device 1 a receives a firmware update instruction from the management server 2. On the other hand, even in the case of a hardware failure of the CPU of the communication device 1a, a function for reducing the service interruption time can be realized by temporarily saving management information to another communication-connected device by the same processing. .

FIG. 8 is a third diagram showing a processing flow of the communication system.
FIG. 9 is a fourth diagram illustrating a processing flow of the communication system.
Next, the processing flow of the communication system according to the fourth embodiment will be described in order with reference to FIGS.
First, the update management unit 111 of the communication device 1a detects a failure of the CPU 10 based on a notification from the CPU failure detection unit or the like (step S801). The update management unit 111 detects the start of firmware update based on the detection of the failure of the CPU (step S802). Thereafter, the processing from step S103 to step S116 is the same.

Next, upon receiving a CPU reset response, the update management unit 111 performs a CPU blocking process (step S803). The update management unit 111 displays information about the start of blocking on a monitor or the like in order to notify the user that the CPU has entered the blocking mode. Then, the user physically replaces the CPU and performs a restart operation. Then, the communication device 1a is restarted (step S804). Subsequent processing is the same as in steps S118 to S127.
According to the above-described processing according to the fourth embodiment, the CPU can be exchanged in an in-service state even when the CPU fails.

<Fifth embodiment>
In the fifth embodiment, an example in which the update process is executed after the management information conditions in the CPU are met will be described. As an application example, it is possible to implement a method that is executed after the conditions for storing management information are met. As this method, in the recording destination determination process in the recording destination determination unit 113, the recording destination search process is repeated until a recording destination candidate apparatus satisfies the recording condition. The search process is performed at regular intervals as a regular process.

FIG. 10 is a diagram illustrating a minimum configuration of a communication device that is an information processing apparatus.
The communication device 1 that is an example of the information processing apparatus may include at least the update management unit 111 and the CPU management unit 112 (management information transmission unit, management information acquisition unit). The update management unit 111 detects the start of update of the update target within the own apparatus. The CPU management unit 112 transmits the management information to the recording destination device that temporarily records the management information of the own device, and acquires the management information from the recording destination device when detecting that the update to be updated is completed.

  Each device described above may have a computer system inside. Each process described above is stored in a computer-readable recording medium in the form of a program, and the above process may be performed by the computer reading and executing the program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.
