To solve the explosively growth of the Internet demands, metropolitan area networks (MAN) use SONET to provide huge bandwidth. However, the SONET network is suitable for constant bit rate (CBR) traffic. Therefore, it cannot effectively handle the burst-natured metropolitan area networks traffic. This paper proposed a novel MAN network architecture and protocol by using the wavelength division multiplexing (WDM) technique to efficiently share the network bandwidth among every network nodes. The proposed novel network architecture adopts carrier sense multiple access with carrier preemption (CSMA/CP) that is a media access control (MAC) protocol to handle the variable size IP packet transport on WDM MAN ring network. This paper also shows the simulation results to verify the proposed MAC protocol is able to take more efficiently utilization and lower packet latency. Further developments are proposed to improve the efficiency and add new capabilities such as QoS.
