The fast growing traffic demand in telecommunication networks, by use of the Internet and an increasing number of broadband services for multimedia com- munications, requires new high performance networking technologies. As such, optical WDM networks are playing a pivotal role. Wavelength Division Mul- tiplexing (WDM) with many hundreds of wavelength channels per fiber is ex- tensively being exploited in wide area networks. With respect to the ongoing trend towards a completely packet-switched mode of operation for all services, WDM networks must be prepared accordingly. This work...

Routing and Quality-of-Service in Broadband LEO Satellite Networks describes mechanisms for supporting Quality-of-Service (QoS) strategies that consider properties of low earth orbit satellite networks and their effects on link handover. A graph model representing the dynamic topology of a satellite constellation is introduced based on a new parameter, lifetime. Novel routing and resource reservation algorithms as well as connection admission control strategies are proposed to minimize the handover blocking probability while maintaining QoS requirements. The author also...

Dynamic Routing in Broadband Networks focuses on routing in broadband networks based on MPLS (Multiprotocol Label Switching) and ATM (Asynchronous Transfer Mode). The routing methods are based on the theory of Markov decision processes which forms a very accurate framework for on-line route optimization. The author shows the issue of performance optimization and scalability with respect to dynamic routing of logical connections in broadband networks. The methods used are applicable to routing virtual path connections (VPC) and virtual channel connections (VCC) in ATM networks...

All-optical networking is generally believed to be the only solution for coping with the ever-increasing demands in bandwidth, such as the World Wide Web application.
Optical backbone networks efficiently achieve a high level of traffic aggregation by multiplexing numerous users on circuit-switched wavelength paths - the so-called wavelength routing approach. In contrast, the reduced level of traffic aggregation in access and metro networks makes wavelength routing solutions not adequate. In these network areas, packet-interleaved optical time-division multiplexing with its finer and...
