—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)
—Next-generation wavelength routing optical networks requiring optical cross connects (OXC) in the network have the ability to direct optical signals from any input interface to suitable output interfaces by configuring their internal embedded optical switch matrices. Microelectromechanical systems (MEMS) switches are regarded as the most promising… (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 paper, we propose and study how to provide multipath cross-layer service discovery (MCSD) for mobile ad hoc networks (MANETs). Cross-layer service discovery integrates service discovery into route discovery by taking advantage of network-layer topology information and routing message exchange. Multipath service discovery differs from multipath… (More)
IP Multimedia Subsystem (IMS) and Web services (WS) are service-oriented architectures developed separately for service delivery in the next generation telecommunications, and IT-centric computing environment, respectively. In order to harness services in both of these platforms and to facilitate combining and blending of services, we propose an integrated… (More)
—This letter identifies crosstalk sources in limited wavelength interchanging cross connects (L-WIXC) and calculates the power penalty imposed by this. Specifications for the components used in the L-WIXCs can then be determined for obtaining a specified level of system performance.
