This paper proposes an admission control mechanism based upon two grooming strategies; lightpath-create-first and lightpath-create-last. The key feature of the proposed mechanism considers the condition when multiple identical requests associated with a source, destination, and class of service arrive simultaneously at an edge router. The mechanism is implemented and investigated using a simulation model of a distributed GMPLS-based IP/WDM network. Moreover, a methodology for providing a class of service based on this mechanism is also proposed.
