Restorability Analysis of Two Protection Cycles in Random Mesh Networks

Abstract

This paper studies the total network restorability using only two protection cycles in a mesh optical network with fixed and uniformly distributed working and protection capacities. We present a detailed analysis for the shared case when two cycles share the capacity in a number of edges common between the two cycles, and also for the non-shared case when the capacities are not shared. We study how the restorability changes with respect to different network parameters.
