Performance analysis and simulation of a novel OBS network architecture

摘要

Optical burst switching (OBS) technology is a promising solution for the next generation Internet backbone. However, contention resolution and QoS support constitute critical issues in its services development. We propose in this paper a novel architecture for optical networks suitable for OBS switching, contention resolution, and QoS provisioning. The performance evaluation is realized based on an ad-hoc analytic model and a simulation. The method proposed is based on the re-design of optical switches to include optical delays lines and adapting the signaling protocol.
