Optical Quality of Service (QoS) for different classes of service in dynamic transparent optical networks is here addressed through three Four Wave Mixing (FWM)-aware algorithms. The traffic classes differ in quality attributes, namely, transmission Bit Error Rate (BER) and blocking probability. The algorithms are tested on two mesh topologies against offered traffic, different transmitted power and wavelength grid. Results suggest that in order to simultaneously maintain Optical Service Level Agreement (OSLA) and efficient utilization of the resources, there must be some form of Connection Admission Control (CAC) mechanisms to provide class isolation.

This article addresses the issues of scalable end-to-end QoS in Metropolitan DWDM networks serving as transit networks for IP access networks. DWDM o ering few wavelengths have in the past been deployed in backbone networks to upgrade point-to-point transmission where sharing is based on coarse granularity. This ty p e o f D WDM backbone networks o ering few lightpaths, provides no support for QoS services traversing the network. As DWDM networks with larger numbers of wavelengths penetrate the data-centric Metro environment, speci c IP service requirements such as priority restoration, scalability, dynamic provisioning of capacity and routes, and support for coarse-grain QoS capabilities will have to be addressed in the optical domain in order to achieve end-to-end QoS ove r a D WDM network. We propose a QoS service model in the optical domain called Di erentiated Optical Services (DoS) based on a set of optical parameters that captures the quality and reliability of the optical lightpath.
