This paper investigates and compares the performance of two generalized multiprotocol label switching (GMPLS)-based distributed control and management protocols for dynamic lightpath provisioning in future IP networks. The first protocol is a global information-based link state approach that consists of both an integrated RWA (routing and wavelength assignment) algorithm and a signaling algorithm. Two triggering mechanisms for LSA (link state advertisement) update procedures are considered; one is a periodically-based update and the other is a threshold-based update. The second protocol is a local-information based fixed alternate link routing approach where the signaling protocol is closely integrated with the RWA protocols.
