—We consider a slotted WDM packet switch with limited-range wavelength converters. The performance of this switch is studied using simulations with various types of data traffic. Results show that the slotted WDM packet switch with a small range of wavelength conversion capability can achieve a performance close to that of a switch with the full range of(More)
This paper presents heuristic algorithms that may be used for light-path routing and wavelength assignment in optical WDM networks under dynamically varying traf®c conditions. We consider both the situations where the wavelength continuity constraint is enforced or not enforced along a light-path. The performance of these algorithms has been studied through(More)
We use the analytical model for multi-®bre WDM networks to approximately analyse the network performance of limited-range wavelength conversion WDM networks. In addition, we develop a simple analytical model for multi-®bre networks with limited-range wavelength conversion capability by combining the multi-®bre network model and the limited-range wavelength(More)
—We study the impact of wavelength conversion capability on wavelength routing WDM networks with fixed shortest-path routing. We propose a method for implementing wavelength routing in a WDM network with partial wavelength conversion capability. Simulation results show that such partial wavelength conversion networks provide a performance in between that of(More)
—In this letter, we introduce a general model for describing the connection setup in various wavelength-routing optical cross-connects with limited conversion capability. It enables us to determine if a given connection pattern can be supported, and to calculate the blocking performance of the cross-connects.
