The Research on Assembly Algorithm Supporting QoS in OBS Networks

The bursting aggregation assembly in edge nodes is one of the key technologies in OBS (Optical Burst Switching) network, which has a direct impact on flow characteristics and packet loss rate. A new optical burst assembly technique supporting QoS is put forward in this paper, which can automatically adjust the threshold along with the increasing and decreasing volume of business, reduce the operational burst, and generate corresponding BDP (Burst Data Packet) and BCP(Burst Control Packet). In the end, it is simulated through OPNET Modeler software. Simulation results show that the technology can effectively reduce the packet loss rate, and enhance the QoS (Quality of Service) capabilities of the OBS networks.
