—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)
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)
—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.
—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)
—For all-optical WDM networks, we study the impact of the number of transceivers and their tunabilities on network performance. Results have been obtained through simulations for networks with different topologies. We find that a network with a limited number of transceivers in each node and limited trans-ceiver tunability can still perform close to one(More)
