Research of hierarchical coordination method of inter-area routing in telecommunication network

The improvement of the scalability of routing decisions is quite relevant in modern telecommunication networks. In this regard, effective approach is associated with the implementation of hierarchical routing. This involves carrying out a structural and functional decomposition of the network, based on the introduction and supporting of multi-level routing decisions. However, the existing protocol implementation hierarchical routing does not contribute to maximization of the scalability of routing decisions because that only applied structural hierarchy and functional aspects are not involved. In this paper the method of hierarchical inter-domain routing based on the goal coordination principle was supposed.
