Traffic Grooming in Optical WDM Mesh Networks

Optical networks based on wavelength-division multiplexing (WDM) tech­ nology offer the promise to satisfy the bandwidth requirements of the Inter­ net infrastructure, and provide a scalable solution to support the bandwidth needs of future applications in the local and wide areas. In a waveleng- routed network, an optical channel, referred to as a lightpath, is set up between two network nodes fo...
