Method and device for forwarding message via aggregate port (AP)

Abstract

The invention provides a method for forwarding a message via an AP. The method comprises that the AP including n effective member links is created, a unique identification is distributed for the AP, and n represents a positive integer greater than or equivalent to 1; a first type of message is obtained, and a secrete key corresponding to the first type of message is determined according to a feature value in the first type of message; a message characteristic identification is generated according to the unique identification and the secret key; a pre-configured export link table including export link indexes in one to one correspondence with the effective member links in the AP is matched according to the message characteristic identification; and the first type of message is forwarded according to a matching result. At the same time, the invention also provides a device for forwarding the message via the AP. According to the device and method, the message characteristic can be utilized more effectively, link redundancy is ensured, and the flow stability is also ensured.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for forwarding messages through an aggregation port. Background technique [0002] Aggregate Port (AP for short) is to bundle multiple physical links together to form a logical link, which can be used to expand link bandwidth and provide higher connection reliability. [0003] AP supports traffic balancing, which can evenly distribute traffic to each member link. The AP also implements link backup. When a member link in the AP is disconnected, the system will automatically distribute the traffic of the member link to other effective member links in the AP. [0004] According to the source MAC address, destination MAC address, source IP address, destination IP address, L4 layer source port number, L4 layer destination port number, etc. of the packet, the AP can use one factor mode or several factor combination modes to analyze the packet flow. To distingu...

AI Technical Summary

Problems solved by technology

[0010] If the peer device of the aggregation port is a stacking device and the stacking device is connected to a different server, traffic oscillation will cause user migration

[0011] If the peer device is deployed asymmetrically, the traffic redistribution will cause the peer device to think that this is a new flow and need to learn the address again, resulting in TCP disconnection, the server loses user information, and the user will be disconnected from the network.
