An Analytical Method of Network Service Scalability

The research of network service scalability is essentially the research of the capability of providing service, which is based on services and the relationship among the services. However, most of the researches ignore the systematic research on analytical methods of service scalability in network systems, owing to the complexity and the diversity of the network system. In this paper, we propose an analytical method of network service scalability, which is composed of a network description model and a service evaluation model. The method uses the network description model to describe services and the relationship among them. After presenting the network description, the method uses the service evaluation model to analyze the network service scalability. For analyzing and simulating purposes, we select three P2P network models, which are different with each other in network topologies as an example. Our simulation results which are in accord with the results of the example analysis verify the correctness and applicability of the analytical method.
