A kind of novel architecture of unslotted photonic packet switching wavelength division multiplexing(WDM) ring network with tunable transmitters and fixed receivers was proposed. In the network thewavelength was used as optical packet label and node media access controller (MAC) address. Opticalpackets transmitter was made up of tunable laser that was modulated at 10, 40 Gb/s or higher. Opticalpacket receiver was made up of Bragg grating, circulator, and fixed receiver. Used as metropolitan accessnetwork, it is shown through simulation how a multi-token MAC protocol can be implemented to avoidpacket collision and achieve efficient bandwidth utilization. Packet delay, throughput, and packet droppingprobability results are presented under uniform and none uniform Possion traffic.
