Abstract：Because of its scalability, the idea of coarse packet classification can be uti-lized to OBS network. However, due to the limited priorities supported by OBS networks, multi-class burst assembly technique is usually adopted. Hence, a novel map algorithm, i.e. TQ-map, is proposed, which can determine which classes of packets a priority burst can contain, and fit for the multi-class burst assembly. Its most important feature is adaptivity. Compared with S-map, TQ-Map can establish the map relations varying with both traffic condition and QoS requirement, and moreover allocates the burst assembling capacity be-tween packets’ classes fairly, efficiently and differentially. The only one purpose is to match the QoS requirements of high layer’s applications. The simulation results show that TQ-Map can effectively achieve the purpose to support QoS.
