摘　　要：流量控制是保证服务质量、提高网络资源利用率的有效手段,接纳控制作为流量控制的有效途径之一,与网络的流量特征、网络性能有密切关系,尤其在系统重负载时比拥塞控制更为有效。在基于跟踪流量分析视频流量特性的基础上,研究了基于流量模型的流量控制机制的部署与实现,探讨了基于复杂流量模型进行有效带宽估计的接纳控制机制是否能够提高系统性能和网络的复用性能,并通过仿真对典型机制进行了性能比较,最后给出了今后流量复用研究的建议。Traffic control is an efficient means to guarantee quality of service and improve resource using rate, admission control as one efficient way of traffic control is correlative with traffic character and network performance, especially more efficient than congestion control under system heavy load. The performance of admission control which admission judge is based on effective bandwidth through simulation is studied and whether such mechanism could improve the system performance and the multiplex performance are researched on after the property of video traffic through trace is analyzed. In the end, some advice to traffic multiplex research is proposed.
