Abstract :
We consider a communication network in which dynamic routing is used for establishing connections that support information transfer between end-users. Link state information is exchanged and maintained up-to-date among network nodes for path computation and network resource allocation. When the population of users is large, the amount of link state information can be overwhelming. A common solution is to use a hierarchical structure. In this paper, we present a method for aggregating link state information in a hierarchical network. We assume that each link state parameter associated with a link is symmetrical in both directions of the link. The key idea for the method is to first reduce the original subnetwork topology to a full-mesh representation that consists of a logical link for each pair of border nodes in the subnetwork, and then encode the link state information associated with the full-mesh representation with an appropriate spanning tree
