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

Especially for the transmission of voice services, if the recovery time is greater than 50ms, it may cause application problems. Therefore, only using the standard-defined LACP protocol for protection cannot meet the needs of developing business applications.

[0031] To sum up, the disadvantages of the LACP protocol are: the use of a timeout mechanism to detect faults is very time-consuming; there is no fault information notification mechanism, and the peer cannot be notified when an error occurs at the local end
