Several self-healing protocols utilizing virtual paths have been proposed in the relevant literature. Those which work in a mesh topology function according to three main rerouting strategies (though specific flooding administrations differ): local rerouting, source-destination rerouting, and local-destination rerouting. Most performance studies of self-healing protocols have considered restoration time as the sole performance metric. This would have to be within the 2s threshold in order to guarantee service continuity. This one-sided metric needs to be completed. In this paper, we propose an extended performance metrics framework in order to catch more performance aspects. In addition, this analysis uses survivability functions to measure the performance of rerouting strategies.

Keywords: ATM/VP transport network, performance metrics, rerouting schemes, survivability functions, performance analysis
