With the advent of the information age, the popularization of PC computers, and the wide application of the Internet, computer information technology has been effectively combined with all walks of life, various new technologies and new services are emerging, and users have more and more bandwidth requirements for data. higher. In order to meet the high bandwidth requirements of a single user, operators require network equipment with large capacity, high access and high processing performance. In order to meet the requirements of large capacity, high access and high processing performance, the current network equipment mostly adopts a distributed system that deploys a large number of CPUs. With the gradual promotion and large-scale use of multiprocessor distributed systems in the telecommunications industry, and the improvement of users' requirements for network equipment performance, the software upgrades of equipment are more frequent.

The current method for implementing device software upgrade is as follows: the device to be upgraded is a distributed device having a global active main control board, a global standby main control board and several interface boards. (1) Under the condition that the global active main control board is running normally, upgrade the global standby main control board and create a version rollback timer; (2) Perform the active-standby switchover to make the upgraded standby main control board the new global one The main main control board takes over the work of the original global main main control board and upgrades all interface boards; (3) when the version rollback timer times out in step (2), the upgrade fails, and the version rollback is performed, and the upgrade ends; Otherwise, confirm the upgrade operation of the new global active main control board, and the version rollback timer will be deleted; (4) upgrade other main control boards in sequence; (5) until all boards are upgraded to the new version, the upgrade process ends. This method has the following shortcomings: 1. The failure of the main control board's active/standby switchover or the failure to upgrade any one of the interface boards will lead to the failure of the entire upgrade, increasing the probability of device upgrade failure; During the process, because the CPU of the interface board will be restarted, the protocol packets sent by the CPU of the interface board need to be sent by the CPU of the main control board. The CPU of the main control board is busy with its own business and controls the device upgrade process, so it may not be able to proxy in time. The protocol packet sent by the CPU of the interface board is sent, causing the network topology to flap.
