A Review of Survivable Transport Networks Based on p-Cycles

p-cycles are a fairly recent addition to the set of basic approaches for transport networks survivability. The main attraction of p-cycle is that it combines the ring-like speed with mesh-like efficiency. p-cycles networks are guaranteed to be protected against single fiber duct failure. However, it is incompetent to provide protection on subsequent failures in presence of a single failure. In this paper we review the various enhancements, which are made in p-cycles to handle multiple failures.
