Abstract :
The work presents a new approach to the design and planning of WDM networks based on joint wavelength and waveband routing (JWWBR). The approach follows the concept of dividing the entire network into suitable subnets with one express node per subnet. Both aggregation of calls into wavebands and segregation of wavebands into individual wavelengths are performed by the express nodes. An algorithm is presented for routing and wavelength/waveband assignment of calls in the network. Performance results indicating various trade-offs in regard to waveband granularity, subnet divisions and traffic pattern are presented.
