Abstract

The present invention provides a CPU message flow control method for distributed exchange router system. By utilizing real-time statistics of the number of various types of CPU message of current system in unit time said invention can monitor the flow quantity of various types of CPU mossage, and can judge that it has need of adopting message control measure to reduce flow quantity of CPU messageor not according to the message control flow threshold value. When the CPU message flow exceeds the CPU processing capacity, said invention can adopt a certain measure to reduce flow of CPU message.

Description

Technical field:

[0001] The invention belongs to the technical field of distributed switching router systems in modern IP communication networks, and in particular relates to a flow control method for CPU messages in a rack-type switching routing device with multiple service boards. Background technique:

[0002] In the modern IP broadband communication network, high-performance switching routers have extremely high strategic significance as the core part of the network. Most of these switching routers adopt a distributed architecture, a multi-slot rack structure, and can be configured with a main control board, redundant backup boards for the main control board, and multiple service boards. Both the main control board and the service board have their own CPU and memory resources, but their division of labor is different. The service board is mainly responsible for forwarding, and can also share some protocol processing that does not require global processing. The task of ...
