%X Several key technologies of optical burst switching(OBS) network are implemented and experimentally verified,including high-speed burst assembling,burst scheduling and burst-mode transmitter and receiver with high receiving sensitivity and fast clock and data recovery time(less than 80ns),which means a flexible and scalable OBS testbed is demonstrated.The TCP performance over OBS is experimentally investigated on this testbed and multi-QoS traffic transmission on the testbed are demonstrated as well.Experimental results show that the performance of TCP traffic is greatly influenced by burst loss probabilities,but can be guaranteed in the case of 0.1% burst loss probabilities.TCP transmission experimental results also point out that the extra round trip time caused by OBS layer has great influence on the available TCP bandwidth.Experimental results verify QoS provision in OBS network.
