Experimental study of dynamic IP topology reconfiguration in IP/WDM networks

With the widespread deployment of IP over WDM networks, it becomes necessary to develop dynamic lightpath and topology reconfiguration mechanisms and reconfiguration triggers that can effectively exploit WDM reconfigurability. A reconfiguration model for overlay IP/WDM networks is introduced. An IP over WDM network testbed has been set up using Telcordia MONET WADM and IP routers. The testbed network and software architecture is presented and the traffic-engineering experiments and convergence measurements conducted over the testbed are reported.
