On the Support of Multimedia Traffic over Optical Burst-Switched Networks

Abid Abdelouahab, Ahmed Mueen and Fathi Taibi

Optical Burst Switching (OBS) is a promising switching paradigm that is very suitable to be deployed in the next generation internet. OBS combines the benefits of various evolving techniques to economize the network traffic through an optical network. However, OBS lacks mechanisms for congestion control and service differentiation, which impedes its support for the Internet multimedia traffic. In this study, new congestion control and service differentiation mechanisms are presented. These mechanisms are based on a new control packet structure, which provides constant transmission overhead and makes the control packet scalable to higher speeds. The simulation results show that these techniques allow the OBS edge nodes to control the network traffic flows and enable the core nodes to maintain a low burst drop rate and provide different services for different traffic classes.
