Abstract :
In this paper, a method of unavailability evaluation for communication network management is proposed. This method supports the management of large-scale communication networks provided to end users. The unavailability model for communication networks and the evaluation procedure is described. The time trend of network reliability can be understood by considering the characteristics of unavailability over short periods. Examples of evaluation of the network unavailability and management scenarios in a communication network are presented. Our reliability modeling and evaluation method can be flexibly applied to various types of network architectures and has been used successfully in our work.
