Analysis of the Requirements for Optical Medium Access Protocol in WDM-based Single-hop Networks

This paper describes the mechanism of existing several WDM(Wavelength Division Multiplexing)-based MAC(medium Access Control) protocols, which shows their characteristics and analyzes the requirements for the MAC protocol in the Optical Internet environments. The requirements lists are supporting variable-length parkets and priority service among network nodes, supporting instant scalability coping with growing IP traffics, simplicity of algorithm, quantity of hardware per node, high throughput and fast access time, etc.. And the existing MAC protocols are analyzed with the proposed requirement lists.
