Medium Access Control Protocols for Robust Wavelength Division Multiplexed Local Area Networks

摘要

The Wavelength-Division-Multiplexing (WDM) network architectures,in general,are based on trans mitters and/or receivers that can be precisely,and speedily,tuned to predetermined,fixed wavelengths.These requirements are not easy to meet in practice.Robust WDM networks do not rely on fixed wavelength channels.Any node that requires a connection with another node dynamically selects a currently unused wavelength in the spectrum.Two medium access control protocols for Robust WDM networks are presented and evaluated.
