Robust-WDM is proposed to realize Wavelength Division Multiplexed (WDM) Local Area Networks (LANs) in the presence of laser wavelength drifts. The approach of Robust-WDM is to design access protocols that can exploit a new wavelength-tracking receiver.We introduce an analytical model that can be used as a tool to design Robust-WDM LANs, and to predict and understand their performance characteristics. The model is designated ifor a class of these networks that relies on an aperiodic-reservation based access protocol and uses a token-passing control channel to organize the right to reserve among nodes. BackgroundMany of the proposed Wavelength Division Multiplexed (WDM) Local Area Network (LAN) architectures are based on devices that are required to perform with extreme stability in terms of laser wavelength. Fast channel tuning over large bandwidths is taken for granted as well. These requirements are expensive to fulfill in practice. It is reported that a 16-channel dense WDM system costs today about US$ 1 million per network node [l]. Obviously, only large public network carriers may find this kind of figures acceptable in long-distance backbones. As far as the local area is concerned, however, the cost effectiveness of WDM has not been verified yet. The Robust-WDM research project [2]-[lo] attempts to address this problem. A Robust-WDM LAN is a broadcast-and-select passivestar-coupler based network. We have designed Medium Access Control (MAC) protocols that can exploit a new WDM receiver technology.
