The use of the Network Layer Packet Redundancy Scheme in the OpMiGua hybrid network

by Skavdal, Arnt Erling

Abstract (Summary)
This thesis proposes three schemes combining Optical Migration Capable Networks with Service Guarantees (OpMiGua) and the Network Layer Packet Redundancy Scheme (NLPRS) in order to improve the packet loss rate performance of the Best Effort (BE) class in OpMiGua. The proposed schemes send redundancy packets as BE-packets or over the Guaranteed Service (GS) path, while the regular data packets are sent as BE-packets. This thesis also investigates the performance of the proposed schemes. First, the OpMiGua and NLPRS are described. Second, a simulator model of the combined is presented. Based on the results obtained from simulation, the performance of the proposed schemes is quantified and presented.The simulations have revealed that all three schemes reduce the packet loss rate for the evaluated scenarios. Hence, the proposed schemes improve the performance of the BE-class. By combining OpMiGua and NLPRS with the proposed schemes, the NLPRS increases its tolerance for high offered load.
