Routing and capacity assignment in backbone communication networks

Routing optimization and capacity assignment in multi-service IP networks

This dissertation investigates routing optimization and capacity assignment in IP networks with multiple services. Both are key processes of traffic engineering and network planning, needed for cost-efficient, quality of service (QoS) aware operation of IP networks. Routing optimization provides a means to balance the traffic load in the network with the goal to improve quality of service. The ...

QoS Routing and Management in Backbone Networks

The Internet supports a growing number of services ranging from legacy web browsing to the more recent online gaming or voice over IP. Among these services, some emerging network applications, such as IP television or video on demand, have stringent requirements in terms of guaranteed endtoend performance. These requirements translate into multiple quality of service (QoS) constraints related t...

Routing and Wavelength Assignment in Optical Networks

Wavelength Assignment and Routing in WDM networks

With wavelength division multiplexing (WDM) several optical signals can be transferred in a single optical ber [6][7]. This technology allows more e cient use of the huge capacity of an optical ber but also poses new network design and management problems, especially when wavelength conversion is not possible in the nodes. In this paper we consider the routing and wavelength assignment problem ...

Distributed QoS Routing for Backbone Overlay Networks

In recent years, overlay networks have emerged as an attractive alternative for supporting value-added services. Due to the difficulty of supporting end-to-end QoS purely in end-user overlays, backbone overlays for QoS support have been proposed. In this paper, we describe a backbone QoS overlay network architecture for scalable, efficient and practical QoS support. In this architecture, we adv...
