ABSTRACT
With the rapid increase of network scale, the eectiveness of the nodes has produced important influences on the network performance. Therefore, analyzing and computing accurately the nodes eectively depict has important significance for network trac. So, researchers at abroad and home had done a lot of research work on the flow of network computing. Sahinoglu M and Libby D L [1] evaluate the reliability of the network by using probability expression. In order to consider network trac factors and connectivity, liu aimin and Liu Youheng[2] put forward the communication network reliability evaluation measure. Wei Juan and Hu Jun[3] put forward the PFB algorithm to depict the network trac.
