Implement method for automatic topology discovery of resilient packet multi-ring interconnection network

Abstract

The invention is a method for realizing automatic topology discovery of a kind of elastic grouping multi-ring mutual-connection method, at first, the standardized grouping ring RPR single ring network media is accessed to the address which controls the MAC, the representation method is defined extensively, then constructs the double direction chain and the topology information table unit structure of the tree connection, in order to preserve the topology information and the joint information in the network, finally, based on the constructed chain table and the automatic topology discovery., it uses clockwise layering method to realize the automatic topology discovery of the multi-ring mutual-connection network. The invention has character of distributed automatic control of single ring structure and the merits of automatic topology discovery algorithm, it solves the problem of route information automatic discovery and the automatic control of the RPR multi-ring mutual-connection network topology, based on the topology information and the joint information in the chain table and the information table, it can complete the calculation of the second layer route, thus, any joint in the network can works out the route series to other joint in the network quickly.

Description

Technical field: [0001] The invention relates to a method for realizing automatic topology discovery of an elastic packet multi-ring interconnection network, which is used for realizing the automatic discovery of topology information such as network nodes and link status in a multi-ring interconnected elastic packet ring network, and belongs to a communication and information system The field of network transmission technology. Background technique: [0002] At present, the rapid development of the IP-based Internet makes communication networks gradually shift from a circuit-switched, optimized way of carrying voice services to a packet-switched, optimized way of carrying data services. Traditional telecom operators have begun to upgrade the original inter-office relay network to a multi-service supply platform within the metropolitan area (10-100 kilometers). For SDH / TDM (Synchronous Digital Series / Time Division Multiplex), which mainly transmits voice services, The transmission...

Problems solved by technology

Although the RPR technology adopts many new mechanisms to improve the resource utilization efficiency of the ring network, the architecture of a single ring will cause a waste of bandwidth to a certain extent, and the resource utilization efficiency is not high.
