Abstract
|
Optical burst switching (OBS) has been proposed in the late 1990s as a novel photonic network architecture directed towards efficient transport of IP traffic. OBS aims at costefficient and dynamic provisioning of sub-wavelength granularity by optimally combining electronics and optics. This paper surveys work on contention resolution and node scalability performed within the TransiNet project. Both topics represent key challenges in highly dynamic optical networks and assessing their performance is critical for deciding on their viability. After a brief introduction to OBS, results of studies on the effectiveness of contention resolution in a Germany reference network scenario are presented. Then, node scalability is presented from a performance and technology point of view. Finally, conclusions are drawn regarding the performance and viability of OBS.
