Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 138)

Abstract

According to the upstream TDM in the system of Ethernet passive optical network (EPON), a dynamic bandwidth allocation algorithm (DBA) based on the mechanism of the multiple traffic prediction-correction is presented in this chapter. To improve the real-time performance of the bandwidth allocation, this algorithm forecasts the traffic of varying priority services, then corrects forecast error according to its Gaussian distribution characteristics, which will make traffic prediction closer to the real traffic. The simulation results show that proposed algorithm is better than the existing DBA algorithm. Not only can it meet the delay requirement of high priority services, but also control the delay abnormity of low priority services. In addition, with rectification scheme it is obvious in improving the bandwidth utilization.
