A generalized optical burst assembly mechanism(GOBA) to support multi-service is addressed.Using the minimum tolerable time delay of all the service as the assembly time,this mechanism assembles these different services into a generalized data burst(GDB) with different granularities in the OBS edge node.Comparing with the MSMAP mechanism,the GOBA can significantly decrease the overtime rate of total services by about 10%,reduce the burst conflicting ratio by about 15%,and increase the channel utilization ra...
