All-optical networks are networks for which all data paths remain optical from input to output. With rapid development of optical technology, such networks are a viable choice for the high speed wide area networks of the future. Wavelength division multiple access (WDMA) currently provides the most mature technology for all-optical networks. We discuss a(More)
In recent years, there has been a lot of interest in providing real-time multimedia services like digital audio and video over packet-switched networks such as Internet and ATM. These services require certain quality of service (QoS) from the network. The routing algorithm should take QoS factor for an application into account while selecting the most(More)
Many audio and video \play-back" applications require that all of their packets arrive within their play-back time. Furthermore, the applications with the hard real-time requirements also require guaranteed service from the network. These applications are covered under the \Guaranteed Quality of Service" speciications by the IETF. It guarantees that the(More)
All-optical networks are networks for which all data paths remain optical from input to output. We discuss a class of wavelength division multiple access (WDMA) networks that are homogeneous in the sense that each node contains both an input/output port and a switch. We focus on permutation routing problem and first present a lower bound on the number of(More)
