Analysis of burst scheduling for dynamic wavelength assignment in optical burst-switched networks

We discuss the benefits and limitations of the dynamic RWA in a centralised optical burst-switched network architecture. We present systematic comparison between the performance of the dynamic and static RWA in terms of QoS provisioning and bandwidth utilisation. Additionally, we consider a new component in the WROBS architecture, namely the request scheduler. We demonstrate that its application to the dynamic RWA significantly improves the performance of the WROBS.
