Method, device and network equipment for upgrading distributed communication system software

Abstract

The invention provides a method, a device, an engine card, a service card and network equipment for upgrading distributed communication system software. The method comprises the steps of automatically obtaining upgrading judgment information of a software packet on the engine card and the service card; and judging whether to upgrade a software packet in a new version or judging the damage of software packets so as to redistribute software packets. The user interference is reduced to enhance the automation degree in software upgrading, and when a fault occurs in a file system and a software packet is damaged, the file system can discover the fault and repair automatically the fault so as to enhance the operation stability of the system.

Description

technical field [0001] The invention relates to a software upgrading method and device of a distributed communication system, an engine card, a service card and network equipment, and belongs to the technical field of data communication. Background technique [0002] A distributed communication system generally includes at least one main control engine card and several service cards. The main control engine card is responsible for configuration management and flow control of the entire system. The service cards provide network ports for establishing connections with external devices and are responsible for forwarding service data flows. For the sake of system stability, a backup engine card may also be included. The backup engine card is similar to the service card in the software package upgrade process. [0003] A typical distributed communication system structure is as follows: figure 1 shown. Wherein, the boot device is a boot boot chip when the system is reset, and an...

Problems solved by technology

[0007] The defects of the above upgrade process mainly include two aspects: one is that when performing the upgrade, the user needs to enter the command line to manually input the upgrade command, which limits the degree of automation of the system upgrade and update; Package damage, such as misoperation or file system failure, the system cannot detect and repair automatically, some systems will perform file comparison, but after the verification error, only a simple prompt can be given, and the running state still cannot be restored. In this case The corresponding faulty engine or service card will not be able to start normally. If a single service card fails, it will at least affect the data processing business associated with the card. If it is an engine failure, it will cause the entire communication equipment system to fail

Due to the existence of these two defects, it also affects the stability and fault recovery ability of the communication system as a whole
