A Hysteresis Algorithm for Dynamic Bandwidth Allocation Based on VBR Video Traffic Prediction
Yumin Feng · Journal of the China Railway Society · 2005
A novel dynamic bandwidth allocation algorithm named the hysteresis algorithm is presented based on VBR video traffic prediction in this paper, The buffer size requirement and cell loss rate are both improved significantly compared with threshold algorithm presented by Girish and the allocation scheme based on GOP scene detection presented by Youssef. The proposed algorithm gives attention to both CLR and utilization at the considerate low cost (the reallocation frequency2%) according to a number of simulations. And the bandwidth reallocation process is only triggered when the queuing length of buffer surpasses the roundabout threshold so that the computing complexity is low, which is easy to online realization.
