Resumo

Despite the research advances in intra-domain lightpath provisioning in Wavelength Division Multiplexing networks, efficient and practical schemes for path computation and resource advertisement in multi-domain mesh networks still need to be developed. Most of the solutions proposed in the literature lacks the ability to convey optical network-specific Traffic Engineering information and are based on a periodic message flooding technique. This paper proposes three novel solutions for inter-domain lightpath provisioning in WDM circuit switched mesh networks. Two routing advertisement schemes and two path and wavelength selection criteria for the PCE architecture are proposed. The solutions provide a complete inter-domain routing and wavelength solution. Simulation experiments show the effectiveness of the proposed solutions which significantly reduce the total amount of message exchanged as well as overall call blocking. (C) 2015 Elsevier B.V.
