p-Cycles: An Overview
One of the most promising techniques of network protection i.e. p-Cycles (pre-planned, preconfigured-cycles) is reviewed in this paper. In this paper we provide a survey of the main work on p-cycles to date. The characteristics of p-cycles and various types of protection provided by them are discussed. Finally, some possible extensions or enhancements of the p-cycle concept are discussed.
