Problems solved by technology

Because data packets and control packets share a stack board for data transmission, and when the stack board is abnormal, the data packets and control packets will impact the CPU in the stack board, causing the CPU temperature to be too high and affecting normal operation. message transmission, thereby affecting the stability of the VSC system

Embodiment Construction

[0058] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0059] figure 2 It is a schematic flow chart of a method for message forwarding according to an embodiment of the present invention; figure 2 As shown, the method includes:

[0060] Step 201, according to the ACL of the active device or the backup device, the first filtering is performed on the received message to obtain the message processed by the own device;

[0061] Here, in the VCS system, in order to prevent irrelevant messages from attacking the CPU of each device in the VCS system through the Ethernet port of the main device or the backup device, it is necessary to analyze the data received by each device in the VCS system Packets are filtered. Spe...

Abstract

The invention discloses a message forwarding method, which includes: filtering the message to be received for the first time according to the access control list (ACL) of the main device and the standby device to obtain the message processed by the own device; The packets processed by the device are forwarded to the active device or the standby device for processing through the virtual out-of-band stacking link. The invention also discloses a message forwarding system at the same time.

Description

technical field [0001] The invention relates to message transmission technology, in particular to a method and system for message forwarding. Background technique [0002] In order to meet the data exchange requirements of large-scale networks, virtual switch cluster (VSC, Virtual SwitchCluster) technology has been applied. The interface of the middle stack board interconnects multiple single devices. Generally, the role of each device in the VSC system can be divided into active device and standby device. Wherein, the main device can only have one, which is mainly used to send control commands to each backup device in the VSC system to control the stacking link switching of each backup device; the backup device can have one or two The above is mainly used to receive the control command sent by the master device, and switch the stack link according to the received control command. [0003] The forms of interconnection between the active device and the standby device are d...
