Ethernet over photonic packets: convergence model and performance assessment

Abstract

An edge-node traffic adaptation unit aimed at transporting Ethernet traffic over photonic networks is proposed. Performance assessment is performed through a novel semi-analytical procedure using real traffic traces bearing self-similarity features This method is able to take into account asynchronies between LANs and edge nodes. Results compare the number of LAN-to-LAN interconnections allowed by transparent photonic packet switching compared to conventional circuit switching Statistical multiplexing can significantly improve the number of VPNs despite overheads imposed by limitations of current photonic technology and traffic self- similarity. Design guidelines arising from the present results are briefly discussed.
