Automatic topology discovery mechanism for ring-based mine next generation network

Abstract

Supported by the concept of Mine Next Generation Network, more and more attention has been paid to the Transmission Layer Platform technology in the mine communication network. It was recommended that MNGN-TLP to be made up of some connected rings, which helps to make more use of the given transmission bandwidth for each network node. In this paper we proposed a novel mechanism for automatic topology discovery in ring based network. It starts the global automatic topology discovery process from marginal sub-rings. Each time the global automatic topology discovery command enters a new sub-ring. The command will be updated by adding the new sub-ring’s local topology pattern into the command. After the automatic topology discovery command reaches a marginal sub-ring, it will be absorbed. Following the above process, the global pattern for MNGN-TLP can be built up.
