Availability-aware design in FIPP p-cycles protected mesh networks

Failure-independent path-protecting (FIPP) p-cycle is an extension of the basic p-cycle and an alternative approach for providing fully pre-connected protection paths with end-to-end failure-independent path protection property. We study the unavailability of end-to-end traffic in FIPP based mesh networks, which are designed to protect against single failures and present an availability-aware network design method. Our results show that although FIPP is more efficient in terms of spare capacity redundancy than basic p-cycle (Kodian et. al, 2005 ), when the network design limits the service unavailability, FIPP tends to be less efficient and its redundancy is 8-13% more than basic p-cycle. We present our analysis and discussions on these findings.
