—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 propose and investigate three connection admission control policies for the establishment of label switched paths (LSPs) in IP/ MPLS over optical networks. We show that the policy of establishing LSPs ®rst in the optical layer achieves a better blocking performance. We examine the effect of the number of add/drop ports of optical cross-connects (OXCs) on(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)
