Research on high reliability in redundant link aggregation mode

Abstract

Now, with the rapid development of the Internet, the requirement of bandwidth and reliability of backbone link is higher. In traditional Ethernet networks, it needs to pay a high price to increase the network bandwidth, if you use high-speed equipment, so not only the cost is high, but also the network is not flexible enough. In order to ensure the stability and reliability of Ethernet network, this paper proposes a redundant link aggregation technique, without replacing the equipment, and bundling multiple physical interfaces into a logical interface to increase the bandwidth of the link, dynamic and effective backup links can also be used to improve the reliability of links between devices. Redundant link aggregation can not only improve network bandwidth resources, but also solve the problem of network congestion.
