Separation of contiguous cells as a result of a WDM switch architecture
We consider a broadcast-and-select (single hop) photonic ATM switch architecture which operates under schedules that mask the transceiver tuning latency. Within this work, we develop a set of expressi...

Recentdevelopments in optical WDM technology have opened up many newchallenges and opportunities for network designers. The availability of increasinglyadvanced optical devices, such as add-drop-multiplexers and wavelength routers/cross- connects,is pushing this technology beyond simple point-to- point deployment andmore towards applications in end-to-end networking. These trends will requiremore advanced network control features in order to take fulladvantage of the optical fiber bandwidth. Although much work hasbeen done on static WDM network provisioning, the issue oflightpath channel control in practical network environments needs further investigation.New protocols are required to provision channels for various higher-layerprotocols, and these schemes must make efficient use of keynetwork resources such as wavelengths and switching/conversion capacity. Optical channelsurvivability is also an important concern and various types ofschemes can be envisioned.
