一种基于区分服务的适应性带宽控制策略

An Adaptive Bandwidth Allocation Controller Based Differentiated-services

基于区分服务(DiffServ)这种对各种IP业务,尤其是对QoS要求不断增长的实时通信量提出解决方案的模型,文章根据应用的不同将多种应用在中间节点上采用两种不同等级的策略进行带宽和缓冲区分配,并且进行自适应性调节,使得节点的资源利用率最大化。

With the regard to traffic increment of IP operation, especially the real time applications requiring the quality of service, this paper propose a differentiated strategy of buffer size and capacity allocation to two types of applications on the basis of the DiffServ model. By tightly controlled and adaptive adjustment of the allocated buffer size through the reference queue length, the utilization of resource in the router or switch will obtain maximum efficiency. To validate the proposed algorithm, it has fulfilled a variety of simulations and network environment.
