Abstract

As a link failure may lead to severe burst loss in optical burst switched networks, survivability has emerged as one of the most important issues in the design of the optical networks. In this paper, we propose the 1+X protection scheme, which is a novel protection scheme that not only reduces the loss of burst caused by a link failure but also improves the efficiency of resources in OBS networks. Through numerical analysis, we confirm that the proposed 1+X protection scheme has better performance than conventional schemes in terms of reservation redundancy, end-to-end delay and resource efficiency.
