Method, system and relevant device for collecting network topology information

Abstract

The invention discloses a method for collecting network topology information. The method comprises the steps of sending a request message for management and maintenance for collecting the network topology information, receiving a response message for running management and maintenance carrying topology information and collecting the topology information carried in the response message. The invention also discloses a system and a relevant device for collecting network topology information. The invention extends the functions of an OAM message mechanism, finishes the work of collecting the topology information of PBB networks, simply and conveniently collects the topology information of the PBB networks, and solves problems caused by collecting the network topology information through manual work when the networks are frequent in topology change, thereby providing necessary information for establishing a PBB-TE tunnel, accelerating the research process of dynamically establishing the PBB-TE tunnel and playing a key role in promoting the deployment of PBB network service and traffic engineering service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and related equipment for collecting network topology information. Background technique [0002] Provider Backbone Bridge-Traffic Engineer (PBB-TE), or PBT, is a backbone network technology, which is a derivative technology of Ethernet, and realizes the connection-oriented characteristics of Ethernet. PBB-TE is applicable to a provider backbone bridging (Provider Backbone Bridge, PBB) network, and various services are provided by setting a PBB-TE tunnel in the PBB network. [0003] At present, the PBB-TE tunnel is implemented through static configuration according to the topology information of the PBB network. The static configuration technology is relatively simple, but it also has certain defects. For example, when the network topology changes frequently, the configuration work will be heavy. In addition, when the network scale is relatively l...

[0006] Through the IGP protocol, there is a certain complexity in completing the collection of PBB network topology information

The IGP protocol is a protocol dedicated to autonomous network systems, not a protocol formulated for PBB networks. Therefore, using the IGP protocol to collect PBB network topology information requires major changes to the PBB network equipment and the IGP protocol, so that the collection of PBB There is a certain complexity in the network topology information
