The number of functional boards required by the site is also increasing. . Many years ago, only one primary subrack was connected to a network element to meet the business needs. Now, it is very common to access multiple subracks under one network element.

For the upgrade indicators of communication equipment software, it is mainly to see the efficiency of software upgrade and the success rate of upgrade. The less time it takes to complete the upgrade, the more boards that are successfully upgraded, which means that the less time for business interruption, the shorter the time for failure recovery, the less impact on users, and the additional loss to the entire communication market. There will be less. Therefore, providing an efficient and stable device software version upgrade method has become a goal pursued by various network operators.

Currently, the software upgrade method of the board is used by the NMS to download all the software files to be upgraded to a main control board through FTP (File Transfer Protocol). Then, the software that needs to be upgraded is distributed through the main control board. Go to the corresponding board and activate the board to complete the software version upgrade. All boards in a network element must control the scheduling and execution of software upgrade tasks through this main control board. As the number of subracks connected to a network element is increasing, the number of boards of the same type may be more and more. The increase in the number of boards of the same type that are upgraded in parallel will inevitably lead to a decrease in the success rate of the upgrade. Because there is only one main control board, it also needs to process other non-upgrade tasks at the same time, because the total number of other non-upgrade tasks is not Reducing, even if artificially limiting the total amount of concurrent upgrades, it is very likely that the upgrade task schedule will not occur, or the upgrade task will affect other non-upgrade task schedules.

As shown in Figure 6 and Figure 7, after upgrading the intermediate board to the upgrade agent board, you can upgrade the board from the subrack. The main control board obtains the upgrade configuration file. The upgrade process of the board includes the following steps:

Step 401: The main control board receives the first upgrade package and the first upgrade command delivered by the network management server.

Before the first upgrade package is delivered, the network management server queries the main control board that is currently Does not include the same upgrade software as the first upgrade package. If it does not exist, it will not be delivered. If it does not exist, it will be delivered to a newly created upgrade directory on the main control board. The upgrade software that exists in the main control board links these upgrade software to the newly created upgrade directory in a hard link manner.

The third upgrade configuration file includes multiple types of board types, software names included under each type of board, and paths that are stored by default in the newly created upgrade directory.

Step 402: The main control board splits the first upgrade software package, and transmits the second upgrade software package obtained by the split to the corresponding upgrade agent board.

According to the upgrade instruction of the network management server and the type of the board from the subrack, the main control board obtains the second upgrade software package according to the splitting of the first software package, and transmits the second software package to the corresponding Upgrade the agent board.

The main control board queries the type of the board that is included in the subrack. The third upgrade configuration file obtains one or more types of software that need to be upgraded on the board and the default path of the software in the newly created upgrade directory. Search from the newly created upgrade directory and send the found software to the upgrade agent board corresponding to the slave subrack.

Step 403: The main control board sends a board software upgrade command to the upgrade agent board on the slave subrack.

The upgrade command includes a board software load command and a board software activation command.

Step 404: After the upgrade agent board receives the board software upgrade command, split the second upgrade software package, and perform software upgrade on the board on the slave subrack.

After the upgrade agent board receives the board software loading command, the upgrade software that is split by the second upgrade software package is sent to the board of the slave sub-rack according to the second configuration file. . The second upgrade configuration file includes a type number of a plurality of types of boards, an upgrade priority of multiple types of boards, and multiple types of software upgrade priorities under multiple types of boards, and multiple types of boards. Multiple types of software names and paths where the software is stored by default.

After all the boards are loaded from the subrack, the main control board upgrades the subracks according to the corresponding subrack number, subrack priority, and upgrade proxy address in the first upgrade configuration file. The agent board issues the activation command from the subrack. The upgrade agent board is configured according to the type of the board in the second upgrade configuration file, the upgrade priority of each type of board, and the software under each type of board. Upgrade the priority and activate the sequence of each type. If the priorities are the same, activate them at the same time. If the components have the same priority and are activated at the same time, the components with different priorities are activated in sequence. .

Step 405: The upgrade agent board receives the software upgrade progress of the board, and sends the progress of the overall board software upgrade from the sub-rack to the main control board.

The upgrade progress includes a loading progress and an activation progress. The upgrade agent board receives the software activation progress of the board, and sends the progress of the overall board software activation from the sub-rack to the main control board.

Step 406: The main control board sends the received overall board software upgrade progress to the network management server.

The loading progress information of the single board from the subrack is not reported. Finally, only the loading progress of the subnet from the subrack is reported. After the subrack is loaded, the NMS reports the detailed board software from the subrack. Load status.

Then, the main control board sends the received overall board software activation progress to the network management server. The progress of the board software is the same as that of the board software. Only the overall board software activation progress from the subrack is reported to the network management system. After the activation is complete, a detailed software activation status of the board software from the subrack is reported to the network management server.

In the process of upgrading the board from the subrack by upgrading the proxy board, the main control board is also responsible for the upgrade task of the board on the main subrack and the upgrade task of the board from the subrack without upgrading the agent board. . The board responsible for the main control board is loaded and activated simultaneously with other boards that are responsible for the upgrade agent board.

1. The board from the subrack no longer relies on the main control board of the main subrack to directly load and activate the board software. Instead, it uses multiple upgrade agent boards to share the upgrade task of the main control board. Distributed board upgrades within the yuan.

2. The distributed board upgrade mode greatly relieves the upgrade pressure of the main control board, which enables the main control board to ensure that it does not affect other non-upgraded device management functions when upgrading large-scale device software. .

The distributed upgrade mode can greatly reduce the total number of concurrently upgraded boards on the main control board and the probability of failure due to timeout of the board upgrade. Therefore, the upgrade success rate can be greatly improved.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
