A Bandwidth Allocation Scheme for Satellite IP Broadcast Network

Sun Chen-hua

Abstract

A bandwidth allocation scheme for satellite IP broadcast network is proposed.According to the existing bandwidth allocation scheme,this scheme can make use of spare bandwidth farthest and improve the utility ratio of network bandwidth by adopting a way combining guaranteed bandwidth allocation and dynamic bandwidth allocation.This bandwidth scheme is realized by token bucket algorithm,it is simple and can be used with the quality of service based on business.The results of OPNET modeling and simulation show that this algorithm not only allocates the general bandwidth of the link,but also allocates the spare bandwidth timely,to realize quality of service guaranteed based on user.
