Paper Abstract

This paper studies the virtual topology design of wavelength-routed WDM networks. The focus is on the virtual topology design problem taking into account the quality of service (QoS) requirements of different user applications. To provide diverse QoS levels to meet different QoS requirements, we first propose a QoS model for WDM networks, in which we define four types of optical connections, each providing a diverse QoS level in terms of the transmission bandwidth and end-to-end delay. Correspondingly, we classify the network traffic into four categories with different QoS requirements for using the four types of connections. Based on this QoS model, we then formulate the virtual topology design problem as a linear programming problem with an objective to maximize the network throughput, and give an exact formulation of the problem.
