Simulation and modeling of the restoration performance of path based restoration schemes in planar mesh networks

In this paper we formulate an analytic framework for the restoration performance of path based restoration schemes in planar mesh networks. We analyze different switch architectures and signaling schemes and model their total restoration interval. We also evaluate the network global expectation value of the time to restore a demand as a function of network parameters. We analyze a wide range of nominally capacity-optimal planar mesh networks and find our analytic model to be in good agreement with numerical simulation data.
