Performance Analysis with Synchronize Links and Self-Loop Links between Large Net and Decomposed Subnets

By decomposing the global net to be studied and analyzing the performance of the subnets,the performance analysis of the global net can be quite simplified. In this paper,the performance relations between the global net and its subnets with synchronized links and self-loop links are established. Some necessary and/ or sufficient conditions are given for the case of a global net being decomposed as basically subnets,which are of extensions of the results for the case of a global net being decomposed as general subnets.
