Network design and control for multipoint-to-multipoint communications

This paper considers the network design and control for multipoint-to-multipoint communications. We propose a new routing control method which includes the member connection method and the route setup algorithm. The former implies that each member has its own route to send information to other members. Thus, it can avoid traffic concentration in a particular route. Further, in the route setup algorithm, all routes are generated in parallel, by adding links which have lower cost and lower load one by one, based on grouping by the number of destination nodes on the route. An interesting feature of the proposed algorithm is that every route can be established with a unified algorithm, even when newcomers join ongoing communications. In addition to the above method, we also propose a network design algorithm. It can make the proposed routing control method more effective. Simulation experiments show that the proposed framework is suitable for multipoint-to-multipoint communications. © 2000 Scripta Technica, Electron Comm Jpn Pt 1, 84(2): 18–26, 2001
