Problems solved by technology

However, network failures are very common. In a network with more than 200 routers and 6000 links, the probability of a data plane failure within 5 minutes is 25%, which imposes strict requirements on the speed of the failure recovery mechanism.

Abstract

The invention provides a network fault recovery method and device and electronic equipment, and the method comprises the steps: selecting a plurality of transmission paths which are composed of links between a source node and a destination node and can be connected with a fault link as a plurality of candidate transmission paths of the fault link when the fault link occurs in a network; obtaining a plurality of fault scenes through the plurality of candidate transmission paths, and calculating the occurrence probability of each fault scene in the plurality of fault scenes; and selecting a transmission path for replacing the fault link from the plurality of candidate transmission paths by using the calculated occurrence probability of each fault scene, and transferring the flow in the fault link to the selected transmission path for transmission. According to the network failure recovery method and device and the electronic equipment provided by the embodiment of the invention, the probability of failure of the link in the network is reduced, and the smoothness of the network is greatly improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a network failure recovery method, device and electronic equipment. Background technique [0002] At present, the amount of data carried by the network increases significantly with the increase of the transmission rate. According to the data of HKUST, the link capacity of the data center has rapidly developed from the initial 1 / 10G to 100G today, and the size of the traffic task has relatively little change, which makes 60% to 90% of the traffic task can be within one RTT Finish. When a network failure occurs, a large number of traffic tasks carried on the link cannot be completed. As a result, data centers have ever-increasing requirements for network reliability. However, network failures are very common. In a network with more than 200 routers and 6000 links, the probability of a data plane failure within 5 minutes is 25%, which imposes strict requirements on the ...
