SUMMARYRobust wavelength division multiplexing (Robust-WDM) is a proposal to realize cost-e!ective WDM local area networks (LANs) which can get around the expensive need for laser wavelength stabilization. The type of these networks that relies on an access protocol with aperiodic reservations and lenient-token-passing based control channel (the AR/LTP protocol) is promising. We look at the deployment of the AR/LTP analytical model in designing this type of network. The model is used to predict the e!ect of component and network parameters on the waiting time characteristics of the network. An increase in node operation times (i.e. receiver response time, transmitter select time and reservation period) would result in increasing the average waiting time of a connection request, but the waiting time is more sensitive to the physical span of the network and its size. It is also observed that increasing the inter-reservation threshold may result in little increase in waiting time up to some limit beyond which delay increases rapidly.

“…Robust WDM network is an architecture that relaxes manufacturing and operating wavelength tolerances [6][7][8][9][10][11][12][13] and as a result reduces the cost to levels acceptable for LAN environments. A demonstration prototype has been implemented and several protocols have been proposed for Robust WDM networks [14][15][16][17].…”

SUMMARYWDM networks depend on predetermined, fixed wavelength channels, requiring highly stable lasers and tunable filters. Robust WDM networks, based on dynamically selected wavelengths, relax manufacturing and operating wavelength tolerance requirements leading to low-cost implementations. A node dynamically selects a currently unused wavelength for communication, and uses it for a limited period of time for communication with a destination, thus allowing the network to tolerate wavelength variation with time. A performance model is presented for Robust WDM networks in which the right to establish WDM connections is arbitrated periodically by a control channel based on token passing. Comparison with simulation results indicates the model's ability to predict the network performance accurately.
