Abstract :
Link protection schemes provide high lightpath availability with very limited amount of signaling. When these protection schemes are applied over mesh networks with p-cycles it is also possible to reach service recovery within 50 ms after failure detection. In this paper we compare dedicated and shared link protection schemes over mesh-based ASON/GMPLS networks with defined p-cycles. The comparison is performed in terms of traffic capacity and lightpath availability. An analytical model to calculate the lightpaths availability is also discussed.
