摘　　要：接纳控制解决一个流是否被接纳,以及如何在具有不同需求的流之间分配带宽和时延的问题。优良的接纳控制模型能够在提供有保证的服务质量的同时,提高网络资源的利用率,降低成本。首先简介接纳控制的基本概念、研究意义;然后对现有的接纳控制模型进行分类、归纳和总结,对每一种接纳类型进行详细介绍,分析其性能优劣,指出存在及需要改进的问题;最后,讨论了接纳控制面临的挑战并对其研究前景进行了展望。Admission control determines whether a new arriving flow can be admitted into networks and how bandwidth and latency are allocated to streams with various requirements. Excellent admission control schemes improve the networks utility as while as they provide guaranteed QoS,and reduce the cost. This paper firstly introduced the basic concepts and significance of admission control briefly. It then categorized and summarized the existing admission control schemes,and presented them in detail. After that,it gave a thorough analysis on their performance and problems need to be improved. At the end,it discussed about challenges which admission control was facing and its future development.
