Problems solved by technology

[0017] like figure 2 As shown, when S2( represents RPR node 2, in this paper, for the convenience of explanation, Sn represents RPR node n, Rn represents logical port n, ringn represents the RPR ring numbered n, and the following texts are also described according to this rule, When the logical port of ring3 (and logical port 3, R3) in the RPR node 2 represented by no longer repeats the transmission failure, the RPR nodes represented by S1, S4, and S3 cannot use ring3, resulting in a waste of resources

Embodiment Construction

[0077] As described in the background, in order to solve the problems of the prior art, the purpose of the present invention is to design an aggregation scheme, so that when some RPR nodes fail, other links on the same ring can continue to use, increasing reliability, Improve bandwidth utilization.

[0078] The present invention proposes a kind of communication method of RPR ring network just based on this purpose, such as image 3 As shown, it is a schematic flow chart of a communication method of a RPR ring network proposed by the present invention, which specifically includes the following steps:

[0079] Step S301 , the station determines that there is only one faulty node in the ring network and it is located on a ring of another station in the ring network according to the acquired faulty node information.

[0080] Step S302, the station sets an aggregation interface and a virtual aggregation sub-interface.

[0081] Wherein, the aggregated interface includes logical po...

Abstract

The invention discloses a communication method and equipment of a RPR (Resilient Packet Ring) looped network. By applying the technical scheme, the problem that when interface aggregation operation is performed in a RPR system, and when failure occurs on one node on a certain annular link to result in the unavailability of the whole annular link, the network communication is influenced is avoided. Network communication is carried out in a branched failure link through establishing a virtual aggregation sub-interface according to a failure node so that the reliability of the RPR link is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method and equipment for an RPR ring network. Background technique [0002] RPR (Resilient Packet Ring, Resilient Packet Ring) is a ring network technology. [0003] Compared with the early Token Ring (Token Ring), FDDI (Fiber Distributed Data Interface, Fiber Distributed Data Interface) and other ring networks, it has strong advantages, mainly reflected in the following points: [0004] 1) High loop bandwidth utilization [0005] Such as figure 1 As shown, four RPR nodes form a bidirectional RPR ring network, and both rings can be used to transmit data services and control services; for unicast services on the ring, the destination address is stripped, and the original source address Compared with stripping, after the service reaches the destination node, it no longer occupies the bandwidth on the ring, which effectively saves bandwidth; for multicast fr...
