Inter-ring transmission method in mine next generation network transmission layer platform

摘要

The recent discussion on "Digital Mine" (DM) and "Next Generation Network" (NGN) has made them the hot topics in both the research area of mining and communication network. Then the concept of "Mine Next Generation Network" (MNGN) came up. Following the idea of MNGN, It was also proved to be so clear that the DM integrated transmission platform should be set up first to work as carrier platform. And it was called Mine Next Generation Network Transmission Layer Platform (MNGN-TLP) in this paper. RPR technology was preferred for transmission construction in MNGN-TLP. But RPR was lack in the transmission between rings. In this paper, we establish the frame structure for MNGN-TLP. On this basis, some crucial technologies in the transmission layer were put more emphasis on. We propose a ring-label based inter-ring transmission method for inter-ring transmission. The proposed loose explicit routing algorithm works well for inter-ring transmission. Each ring in the network has its own ring label. The labels of each ring that the packets would pass by were recorded by reverse order in the header of the packet, which helps to build up the path for the reply packet.; based on the scheme, we built up the simulation platform for inter-ring transmission of MNGN-TLP platform in NS2 environment for validation. The packets transmitted between rings can reach the destination correctly with small delay.
