| 摘 要： | 提出了一种适用于卫星IP广播网络的带宽分配策略。与现有的带宽分配策略相比,该策略采用的保证带宽分配和动态带宽分配相结合的方法,可以最大限度地利用系统的剩余带宽,提高了系统的带宽利用率。这种带宽分配策略是通过令牌桶算法实现的,实现起来比较简单,并可以和基于业务类别的服务质量保证机制结合起来使用。通过OPNET建模仿真,结果表明这种算法不但能对链路的总带宽进行预分配,还能对链路的剩余带宽实时地进行动态分配,实现了基于用户的服务质量的保证。

| 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. |
