The failure of a single optical link or node in a Wavelength Division Multiplexing (WDM) network may cause the simultaneous failure of several optical channels. In some cases, this simultaneity may make it impossible for the higher level (SONET or IP) to r ...
With WDM networks, the failure of a single link or component may cause the simultaneous failure of several optical channels, potentially making impossible the restoration by rerouting in higher layers directly using the optical network (SDH, ATM, IP). To a ...
An algorithm that pre-computes a list of routes for each node in the network. An alternate route is also computed in case of overload of the primary one. Simulations show that this algorithm provides routes as good as On-Demand ones. ...
