Abstract

This study search for the availability requirement for the fault management server in high-availability communication systems. According to this study, one founds that the availability of the fault management server does not need to be 99.999% in order to guarantee a 99.999% system availability, as long as the fail-safe ratio (the probability that the failure of the fault management server will not bring down the system) and the fault coverage ratio (the probability that the failure in the system can be detected and recovered by the fault management server) is sufficiently high. Tradeoffs can be made among the availability of the fault management server, the fail-safe ratio, and the fault coverage ratio to optimize system availability.
