Abstract

In this paper, two novel protection and restoration schemes were proposed by using the BC and BR schemes which were originally designed to reduce the bursts loss probability due to contention in OBS network. The 1+1 protection scheme in LOBS can be easily carried out using the MPLS 1+1 protection scheme in the 2.5 layer and burst cloning scheme in the OBS layer. By introducing some new OSPF-TE opaque LSA messages, the burst retransmission scheme can be transplanted into the restoration scheme in LOBS network. Furthermore, the dynamic quality of resilience mechanism to inherit these two schemes according to the QoS requirement of the traffic was also investigated. Experimental study using a LOBS network test bed verified that the proposed schemes suited well in the LOBS network.
