Modeling and analysis of waiting time in a symmetric fast circuit switched robust-WDM LAN with an AR/LTP MAC protocol

Abstract

The 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 for 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.
