Operation control method of distributed router system

Abstract

An operation control method in a distributed router system includes: setting a common operation control command under the management port, and sending the operation control command to the corresponding line card master device through the management port; the line card master device executes the operation control command, Determine whether to operate and control the master device or the slave device. If the master device is to be operated and controlled, the master device executes the command and sends the execution result to the main control board through the management port for display; otherwise, the slave device is operated and controlled. The slave device executes the command by receiving the operation control command sent by the master device through the internal bus, and sends the execution result to the main control board through the line card master device for display. The invention can conveniently carry out centralized operation control such as diagnosis and positioning on each router subsystem, reduces excessive dependence on the hardware environment, and has simple code implementation, simplifies the writing of command functions, facilitates transplantation, and improves diagnosis efficiency.

Description

technical field [0001] The invention relates to an operation control method of a distributed router system, in particular to a processing method for centralized operation control of each subsystem in the distributed router system. Background technique [0002] In the current distributed router system, the operation and control of each subsystem in the distributed router system is mainly executed through the diagnosis command of the management port or the way of logging in to the line card terminal to execute related commands. [0003] The diagnosis command of the management port refers to the operation and control of the table item content or status on each line card by means of the diagnosis command in the diagnosis mode of the router. This method needs to analyze each diagnosis command on the main control board. And the parsed content is distributed to the master device of each line card in the form of a message, and the corresponding diagnostic command function is execute...

Problems solved by technology

[0007] (1) Using the diagnostic command mode of the management port, each diagnostic command needs to be parsed and processed on the main control board and the main device of the line card, and each command function statement displayed under the line card terminal needs to be It is modified to be stored in the memory for display on the main control board. In this mode, not only the amount of code calculation is increased but also the code similarity is very high. It is also necessary to provide diagnostic commands of the management port for all diagnostic functions. Due to the limitations of the actual situation, it is very difficult to realize

[0008] (2) For the diagnostic command mode of the management port to execute the relevant diagnosis of the slave device, it is necessary to use the memory where the table items on the slave device involved in the diagnostic command are located as the space that the master device can access through the internal bus. , not only has certain requirements for hardware design, but also needs to be able to confirm in advance the offset address of the memory where the table entries on each slave device are located, especially when the latter requirement is met, it is very cumbersome to implement

[0009] (3) Using the terminal mode of logging in to the line card, it is required that the client can communicate normally with the master device or slave device of each line card. To operate on the Internet, the master / slave device of each line card must have an independent IP address, which puts higher requirements on the development environment, and in this mode, the number of connected users is limited to 1 user, so in When multiple users need to operate and control, such as positioning or diagnosing table items, multiple users cannot use it at the same time
