Variáveis de mérito de topologias de redes ópticas de transporte de telecomunicações

Abstract

This term paper identifies and proposes semi empirical expressions of new key variables for optical transport telecommunications topologies in order to advance the state of the art relating to the characterization of this type of networks. The following key variables were identified: the nodal degree, the number of hops, link-disjoint pairwise connectivity, node-disjoint pairwise connectivity, clustering coefficient and betweenness centrality. In order to extend the state of the art, two new variables are proposed: average number of hops for working path and average number of hops for backup path, considering an alternative routing strategy from that seen in previous proposed expressions in the literature. Additionally, two semi empirical expressions are proposed to estimate the value of these variables, which requires only the number of nodes and the number of links. Results show that the expressions estimate the values average error less than 12% when compared to the exact values obtained from telecommunication networks.
