Abstract

The ubiquity of IP has led to IP-over-WDM as the core architecture for the next-generation optical Internet. Optical burst switching (OBS) has been proposed to be a competitive switching technology for DWDM networks. The data channel scheduling algorithm is one of the major challenges in OBS. The same-service-to-all model of the current Internet is inadequate for the diverse quality of service expectations of Internet applications and users. Differentiated service (DiffServ) was proposed to provide a scalable and manageable architecture for service differentiation in IP networks. This paper proposes a scheduling algorithm based on an existing LAUC-VF algorithm to support DiffServ and takes advantage of MPLS. Simulation results demonstrate that this algorithm has better QoS performance than the existing LAUC-VF algorithm
