Abstract
An efficient computer network can realize bulk data transfer and real time control with high reliability and precision. Its availability is dependent on its topological structure and network services performed simultaneously. To explore the dynamic interactions between software and hardware failures, generalized stochastic petri net (GSPN) is adopted to model the availability of nodes in the network, and then the study is developed through path selection and service performance evaluation. Network performance indices such as throughput and time delay can be obtained by modeling the network service with queueing theory. With Power formula, this paper presents an integrated availability model. This model considers both topological connectivity and operational performance, developing the availability analysis from the viewpoint of a user.
