HON-OVCS: Virtual Topology Based Architecture for QoS Guarantee in OBS Networks

Optical Burst Switching (OBS) has been proposed as a practical balanced switching architecture between Optical Circuit Switching (OCS) and Optical Packet Switching (OPS). Hybrid Optical Networks (HON) Networks that combines OCS and OBS has emerged to grant the OBS network the ability to support connection-oriented applications. Although efficient in terms of reducing the burst loss probability as well as improving the overall network performance, it provides a limited degree of Quality of Service (QoS). What the authors mean by QoS is the capability of a network to provide a guaranteed level of availability while satisfying strict limits on delay. In this paper, they propose a new hybrid architecture for OBS networks.
