摘要: Optical dense wavelength division multiplexing (DWDM) has yielded unprecedented levels of bandwidth scalability. In order to exploit these gains, new converged multiservice transport setups have been evolved, most notably under the multiprotocol label switching (MPLS) and generalized MPLS (GMPLS) frameworks. These paradigms offer very efficient data-optical integration enable a host service capabilities. As operators deploy technologies, provisioning "subwavelength" demands over wavelengths become crucial requirement, i.e., traffic engineering/grooming. This work addresses grooming in GMPLS networks. Here, novel integrated constraint-based routing algorithms are developed provision subwavelength at both packet-switching lightpath levels. Simulations indicate notable performance gains resource efficiencies with proposed schemes.
