摘　　要：聚合流量是在云计算环境下由多个网络用户数据源叠加后产生的一种聚合流。云计算存在高并发性,在多个服务同时请求接入网络时,传统的单流的接纳控制方法只能处理一个请求,其他服务要等前面的流被处理完才能接受服务,当并发请求的服务越多,等待的延迟也就越大,用户的体验效果也就越差。为了提升网络并发处理的能力,以进一步提高云计算的QoS,提出一种基于聚合流的有效带宽(effective bandwidth for aggregate flow,EBAF)接纳控制算法,通过估计聚合流所需的带宽来执行接纳控制,能同时处理多个服务请求。实验结果表明,EBAF算法的接纳能力相对传统的单流的接纳控制方法能较大的提高云计算服务保证质量。Aggregated traffic is a type of aggregated flow generated by multiple network user data sources superimposed in a cloud computing environment. As cloud computing has a high concurrency, when multiple services request access to the network at the same time, the traditional single-stream admission control method can only process one request, and other services must wait for the previous stream to be processed before receiving the service. The more services there are, the greater the delay in waiting and the worse the user experience. In order to improve the network’s concurrent processing capability and further improve the QoS of cloud computing, an effective bandwidth admission(Effective Bandwidth for Aggregate Flow,EBAF) admission control algorithm based on aggregated streams is proposed. Admission control can be performed by estimating the bandwidth required for aggregated streams, which can simultaneously process multiple Request for service. The experimental results show that the admission capability of the EBAF algorithm can greatly improve the guarantee quality of cloud computing services compared with the traditional single-stream admission control method.
