Method for implementing network interconnection by using link aggregation

Abstract

In the invention, when monitoring the status of ports in local convergence group at two ends of communication network; classifying the monitored state variation information into different types; according to the type of the status variation information, making relevant process. Said method utilizes link convergence control protocol and makes some improvement for it.

Description

technical field [0001] The invention relates to the field of communication equipment, and in particular, relates to a method for realizing network interconnection by using link aggregation. Background technique [0002] Communication systems require the ability to provide users with reliable, uninterrupted services. In this regard, a commonly used solution is redundant backup and active-standby switching technology. Redundant backup and active-standby switching technologies have various backup modes, such as 1+1, 1:1, 1:N, etc. [0003] Specifically, 1+1 backup is a simple protection mode. The main / standby unit in the system forms a logical business function unit, that is, the protected equipment unit has a backup unit, and the main module is responsible for the real-time operation of the business. processing, the standby service remains consistent with the data of the active unit, and a switchover is initiated when a failure of the original active unit is detected, and th...

[0027] 2. Fault occurs: both ports 2 of devices A and B are faulty, such as two-way fiber break of the connected physical line

[0028] 3. Port 2 of devices A and B can no longer receive packets from the opposite end. When the packets from the opposite end cannot be received in three sending cycles, devices A and B consider this port to be faulty.

However, with the improvement of network availability requirements for various network applications, the network fault recovery time is required to be shorter and shorter
