Optical burst switching (OBS), which takes advantage of both high capacity of optical fiber and sophisticated control of electronics, has been considered as a promising paradigm for the modern Internet. In this paper, the recovery procedures for IP over OBS/WDM multilayer network are addressed, which focus on the failure detection and failure localization. Bidirectional forwarding detection (BFD)...
Survivability of optical burst switching (OBS) network was concerned. Bidirectional forwarding detection (BFD) protocol which had the ability of fast failure detection was adopted in the failure detection for OBS links and nodes. Moreover, a BFD-triggered failure detection mechanism combines with Fast Reroute (FRR) is proposed and simulated. Simulation results show that the solution stated above can...
