Abstract :
The total capacity required by a transport network to satisfy demand and protect it from failures contributes significantly to its cost. Previously the spare capacity of a network with a given set of working span sizes has been optimized to facilitate span restoration. Path restorable networks can, however, be even more efficient by defining the restoration problem from an end to end re-routing viewpoint. We now provide a method for capacity optimization of path restorable networks and quantify the capacity benefits of path over span restoration. The further benefits of jointly optimizing working path routing and spare capacity placement in path restorable networks is also quantified by extending the capacity optimization method presented
