In this paper, we analyze the basic characteristics of the propagation network. Using the modeling framework algebra of system (AoS), we convert the complexity of the network structure into the quantity of data. By using OPN (object-process network) which is an executable meta-language based on the mathematical specification of AoS, we build a framework to describe and evaluate the performance of Internet networking during Beijing Olympic Games, which is collected by GPERF, a globally distributed performance measurement system of China Education and Research Network (CERNET). In this framework, we deal with the information of QoS for simulation, visualization, and analysis of userpsilas needs in a uniform algebraic way.
