Abstract:

In order to schedule effectively the asynchronous burst in polymorphous optical burst switching (POBS) and reduce burst loss rate, an asynchronous burst delayed insert scheduling algorithm is proposed. Based on the transmission state of periodic traffic in the source ingress node of POBS network and the overlapping degree of the new assembled asynchronous burst, the proposed algorithm delays the burst to the gap of periodic traffic that has the same destination edge node of the burst. The simulation results show that the proposed algorithm can reduce the asynchronous burst loss rate of POBS.
