Embodiment Construction

[0034] In the traditional dual-system hot backup mechanism, the active main control board (also known as the Active main board) and the standby main control board (also called the Standby main board) can exchange a lot of data, such as routing entries and so on. However, these data can be implemented using traditional backup mechanisms. The present invention will focus on how to back up the data in the internal memory, such as the configuration of chips and modules. Of course, the present invention can be used together with traditional dual-system hot standby. The present invention mainly relates to the management plane. For related design of the service plane such as message forwarding, please refer to the prior art, and the present invention will not describe it in detail.

[0035] Basic hardware environment:

[0036] Please refer to figure 1 , as a preferred implementation manner, the frame-type device mentioned in the present invention includes an Active main board, a S...

Abstract

The invention provides an inter-board communication method, applied to single boards of frame type equipment. The method includes: the upper application instruction of a single board is sent to an opposite terminal single board by virtue of a hardware channel; the instruction sent by the opposite terminal single board is received from the hardware channel, and a hardware module on which the instruction is operated is determined according to the head of the instruction; then corresponding operation information is called and executed; operation result corresponding to the operation information which is returned by virtue of the hardware channel is received; and the operation result is returned to the opposite terminal single board by virtue of the hardware channel. The invention can effectively solve synchronization of key configuration data in hot standby mechanism and provides a more general inter-board communication mechanism.

Description

technical field [0001] The present invention relates to inter-board communication technology, in particular to an inter-board communication technology on frame equipment. Background technique [0002] Most of the large-scale network devices currently on the market are frame structures, also called distributed devices, which are usually composed of a main control board and a service board. This distributed device can seamlessly integrate high-capacity L2-L3 layer switching and rich 4-7 layer business processing. The business environment based on this hardware platform can flexibly expand a series of Ethernet switches, IPS, content auditing and Control, firewall (including application firewall), application acceleration, diversion, and blocking devices, etc. This large-scale hardware platform is often used in various important occasions, such as banking systems, telecommunications systems, university network systems, and industrial security systems. These users have high requ...
