Abstract

Due to the unrealistic definition for paths of network models in previous literature, existing models are not appropriate for real-world computer networks. This paper proposes a modified stochastic-flow network model to evaluate the network reliability of computer networks where data are transmitted through a light path (LP). We focus on a practical computer network, the Taiwan Advanced Research and Education Network (TWAREN). Network reliability is defined as the probability of delivering a maximal flow of no less than a specified requirement from source to sink. It is taken as a performance index to measure the service level of TWAREN. This paper studies the network reliability of the international portion of TWAREN from Taipei to New York that goes through the submarine and the land surface cable between Taiwan and the United States.
