All-Optical IP-over-DWDM MAN Ring Network with CSMA/CP MAC Protocol

Abstract

This paper proposes a Carrier Sense Multiple Access with Carrier Preemption (CSMA/CP) MAC protocol for the DWDM Metropolitan Area Network (MAN) Access ring networks. In the network, each node is equipped with one tunable transmitter and multiple fixed receivers. This protocol provides variable size IP packets directly over all-Optical DWDM MAN ring networks and gives the more efficient bandwidth utilization among nodes. Simulation results show the proposed MAC protocol getting the excellent performance.
