A communication network connection method and its device

Abstract

The invention comprises: setting up a link aggregation group used for aggregating dynamical links between devices at both end of network; when the link has fails, according to the detection message transmitted between the devices at both end, configuring the ports at the both end of network in order to control the communication connection.

Description

technical field [0001] The invention relates to a communication network connection, in particular to a communication network connection device with expandable reliability and bandwidth and a method thereof. Background technique [0002] In the communication system, the status of the communication network is extremely important. It must be able to operate stably for a long time. It is required that the communication network equipment support a redundant backup mechanism, and it can be safely and reliably automatically restored when the communication link fails to ensure network availability. Mechanisms for communication network backup are indispensable. In some cases, the network bandwidth greatly restricts the improvement of equipment processing capabilities. It is necessary to have a mechanism that can enable the communication network to flexibly expand the communication bandwidth on the existing equipment according to the actual situation, so as to ensure the utilization r...

Problems solved by technology

This connection method limits the communication bandwidth, and cannot improve performance to maximize the utilization of network switching equipment; the backup method is also simple, and cannot expand redundant links according to user needs, increase the reliability of network interconnection, and cannot solve communication in case of multi-point failures interruption problem

[0004] The Chinese invention patent with the publication number CN1547330A discloses a "multi-port multi-link communication network backup control method and device". The invention adopts a crossover structure. One end switches the transceiver module, and the two ends have determined the active party and the passive party, so there is no need for negotiation, and the link can be switched quickly. At the same time, the network backup method of one master and three backups is adopted, which improves the interconnection reliability of the communication network to a certain extent. However, this method is only applicable to dual-port active-standby backup, in a switching network with one active and three standby network links and cross-connection, the ports are fixed, and the number of physical links is also fixed. In the case of more than three points of failure, the It is difficult to guarantee normal communication

[0005] The Chinese invention patent with the publication number CN 1859175A discloses a "communication device with internal reliable interconnection". This comparative document proposes a communication reliable interconnection method, but its structure is a parallel structure. Limit the bandwidth of the interconnected frame to a maximum of 2 links, which cannot be based on the user's

[0006] The bandwidth needs to be flexibly expanded; the backup method is unreliable and cannot be expanded, and only another redundant link can be used for backup. Interruption, loss of network backup functionality

There is no way to deal with abnormal network interconnection in time, and the network failure cannot be eliminated as soon as possible
