Efficient Protection in MPλS Networks Using Backup Trees: Part Two—Simulations

Efficient Protection in MPλS Networks Using Backup Trees: Part Two—Simulations In Part One of this study [1], we presented three approaches for organizing backup tree (BT) protection, where a BT was used to protect a group of working paths (WPs) against single failures. Shared BT protection uses less capacity compared to d edicated (path) protection (DP), while having the same fast recovery. Using shared BT protection is particularly suitable for multi-protocol lambda switching (MPλS) networks and can save about 15% capacity resources compared to DP. In this paper, we present a simulation study in which we apply the approaches presented in Part One for several network topologies with different demand scenarios. The effects of network and demand characteristics on the capacity gain obtained with these approaches are analyzed. In addition, the comparison between BTs and 1 : N protection is made. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals
