Challenges and evaluation method in network performability analysis

Aimed at the challenges existing in current network performability research, this paper proposes an analysis architecture for network performability research, in which FMEA of the network, the availability model of the equipment, the topology analysis, the performance evaluation and the design of performability verification platform are integrated into together. This architecture assures accuracy of the performability analysis. According to the performance evaluation criterions, Throughput-based performability, delay-based performability measures to the computer networks are suggested.
