Abstract :

Numerous questions remain unanswered as designers work to perfect the control plane model for multidomain optical networks. Optical Border Gateway Protocol (OBGP) is an extension of BGP that has been suggested by certain projects to facilitate the advertising and signaling of optical information across routing domains. We contend, however, that optical networks of the future provide a chance to circumvent BGP's restrictions, particularly in the areas of routing and traffic engineering. Here, we provide an alternative to BGP/OBGP for route control. Extensive simulations validate our route control model's ability to significantly lessen blocking compared to OBGP, without increasing the volume or frequency of inter-domain routing updates.
