Reliability analysis of core service platform in next-generation network
Naixing Wu · Journal of Communications · 2006
Based on stochastic PetriNets, an analysis method of steady reliability of core service platform in next-generation network was presented. Modeling and analysis of reliability were set up separately on hardware system for both distributed redundant fault tolerant system and distributed N+1 inter-backup system. A software module in-ter-backup method to tolerate fault was proposed, and the way to express the reliability of this module was obtained. The service software system reliability in terms of its modules was analyzed. And finally, a case is studied to show how the hardware and software cooperation to satisfy the specific reliability requirement.
