Ahmad Rostami: Traffic Shaping in OBS Networks

Advances in optical technology have resulted in a huge amount of capacity available for transmission over optical links. Unfortunately the possibilities of efficient usage of this capacity for data and multimedia traffic are
frequently limited by the fact, that switching techniques with fine switching granularity - like packet switching - cannot be efficiently realised in the optical domain using the currently available technology. Optical burst switching (OBS) appears as a promising approach to address this issue. Nevertheless, OBS suffers from packet contention problem that  frequently occurs inside the network. The contention problem has to be addressed before OBS can be really deployed as the next generation IP transport network.
This presentation will discuss novel traffic shaping techniques developed in order to address the contention problem in OBS.
