Abstract

A reconfigurable protection is extended in ASON survivability testbed SURBED, the performance and extra overhead are presented and also compared with several survivability techniques (1+1, shared mesh, rerouting, etc) in SURBED. Pre configured protection cycles (p-cycle) is a kind of preconfigured protection mechanism that can have mesh-like resource efficiency and ring-link protection speed. But under multi-region survivable network, the topology and resource information is not always available due to policy reasons or other else, so distributed approach with agent negotiation is attractable. As the dimensions of WDM optical network grows larger and larger, it tends to be a mesh structure. Based on SURBED, we take extensive simulation to investigate the performance of different signaling strategies by multiregion agent negotiations. Unlike previous work, we focus on the reconfiguring process rather than the switching over operation of control plane in ASON. The backbone is overlaid, in which most of devices are IP router networks. Routers are interconnected by fibers or SDH or WDM links. It is the same with non-reconfigured p-cycle, the reconfiguration need a criterion, and here we use the network real-time performance as a reconfiguration trigger to take actions on pcycle reconfiguration.
