Abstract
Optical burst switching (OBS) has been proposed to be a technology for implementing the next generation optical Internet. In this architecture, burst assembly algorithms have an important influence in the pattern traffic that characteristic this sort of optical networks. On the other hand, traffic coming from new applications (such as video on demand, Voice over IP, online gaming or Grid computing) that have real time and bandwidth constraints, has been experimented a rapid increment. Consequently, we consider important to evaluate the performance of traffic from real time applications over OBS networks. In this paper, we evaluate the effects of implementing a size-based burst assembly scheme at the edge node, on the performance of video transmissions (MPEG4/RTP/UDP) over an OBS network. Through event driven simulation, we conclude about the optimal configuration values for the assembly algorithm in order to guarantee high quality video transmissions. With this purpose, we analyse the PSNR, the delay problem and the data loss due to the relation between the amount of traffic source and the maximum burst size.
