In this paper, we propose a high availability design of a Cable Modem Termination System (CMTS) clusters system based on the software rejuvenation technique. This proactive system maintenance technique is aimed to reduce system outages and the associated downtime cost due to the 'software aging' phenomenon. Different rejuvenation policies are studied from(More)
—In order to reduce system outages and the associated downtime cost caused by the " software aging " phenomenon, we propose to use software rejuvenation as a proactive system maintenance technique deployed in a CMTS (Cable Modem Termination System) cluster system. Different rejuvenation policies are studied from the perspective of implementation and(More)
& Conclusions-In this paper, we investigate the availability requirement for the fault management server in high-availability communication systems. According to our study, we find 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(More)
