Research on the Structure of Telecommunication Networks

摘要

We investigate the structure of telecommunication networks. We consider two nodes in the network to be connected if there had been at least one optical cable between them, and construct explicit network of such connections using data from China TieTong Telecommunications Corporation. It is shown that this telecommunication network form "small world" in which randomly chosen pairs of nodes are typically separated by only a short path of intermediate nodes. Furthermore we giver results for mean-shortest path length(MSPL), degree-degree correlation(DOC), degree distribution and clustering coefficient(CC).
