The trend toward service dependent quality of service (QoS), the demand for guaranteed capacity to integrate telecom services in data communications, the generalization towards more flexible meshed network topologies, and the availability of highly efficient dynamic optical switching architectures bypassing digital signal regeneration, lead to novel constraints on routing. The implementation of light-path routing in a meshed optically switched WDM network is not straightforward as each new request accepted can affect the quality of other previously established circuits. To achieve a requested end-to-end QoS for a specific service the underlying end-to-end light-path, sequence of light-paths in the multi-hop transmission network case, need to offer a service, modulation format, and receiver technology dependent minimum quality of transmission (QoT).
