A message forwarding method and apparatus

Abstract

The embodiment of the invention provides a message forwarding method and a device, which are applied in the field of communication technology, can reduce the consumption of CPU resources in the message copying process and improve the efficiency of the message copying. Specifically, the scheme is applied to a message forwarding device connected with each member of the stack through an aggregation group. The port of the message forwarding device connected with each member of the stack is a member port of the aggregation group. The message forwarding device further comprises a switching unit. Themessage forwarding method comprises the following steps: the first service unit receives the LACP message sent by the stack member through the member port belonging to the aggregation group locally,adds the identification of the aggregation group to the LACP message, and broadcasts the LACP message through the exchange unit. The second service unit receives an LACP message from the switching unit, searches for a member port belonging to the aggregation group locally according to the identification of the aggregation group in the LACP message, and sends the LACP message through the member port belonging to the aggregation group locally.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a message forwarding method and device. Background technique [0002] In communication equipment, software forwarding is usually required for security checks or other reasons, so message copying is required. The usual processing method is to copy the messages that need to be forwarded by software according to the number of outgoing ports. Each Copying a port, its copying efficiency is strictly limited by the CPU capacity, and copying by software is usually slower. It is especially limited in the case of high performance requirements. Taking the stacking system as an example, in order to ensure the reliable operation of the stacking system, the Multi-Active Detection (MAD) method (LACP MAD) based on the Link Aggregation Control Protocol (LACP) is adopted in the stacking system. Realize the stack split fault detection function of the stack sy...

Problems solved by technology

[0004] The problem is that in the process of "forwarding LACP packets from member ports in the LACP aggregation group to stack members for MAD detection in the stack system", the auxiliary detection device uses its central processing unit (Central Processing Unit, CPU ), if the CPU in the main control board uses the software copy method to copy LACP packets, and the number of copies is the number of all member ports of the LACP aggregation group, that is, the stack member ports of all stack members in the stack system The number of copies, at this time, the number of copies is usually more

Among them, the process of copying LACP packets by the auxiliary detection device through the CPU is usually limited by CPU resources. For example, if the CPU resources are less, the efficiency of copying packets by the auxiliary detection device will be low, which will affect the fault detection and recovery of the stack system.
