Quality of service support in optical burst switching
Abstract
Next-generation high-speed Internet backbone networks are required to support a broad range of emerging applications which may not only require significant bandwidth, but also have strict Quality of Service (QoS) requirements. Optical Burst Switching (OBS) is a promising switching technology for the next-generation networks which attempts to address the problem of efficiently allocating resources for Internet traffic. A key challenge in OBS is how to reduce burst loss probability. In this paper, we evaluate two simple QoS models to support different classes of traffic. The simulation results illustrate the performance of an OBS network when different models of QoS are supported. We primarily evaluate the impact on high loss rate in OBS networks when using these models.
