接纳控制研究综述

Research of Admission Control in IP Networks

接纳控制是实现IP网络QoS最重要的手段之一,长期以来一直受到广大研究者的关注,基于不同理论的各种接纳控制机制不断出现。它们在一定程度上都能满足QoS的需求,但也在可伸缩性、健壮性等方面存在一些问题。文章通过对其中多个接纳控制机制的实现原理的分析,考察了这些接纳控制机制的优点和存在的问题,并给出了一些相应的解决办法,这些也是有待进一步研究的问题。

Admission control is one of the most important parts of QoS. And it has been received lots of attention for a long time. Many admission control schemes have been developed, and all of them can meet part of the requirement of QoS. But they also have such demerits as non-scalability, non-robust. In this paper, the fundament of a few admission control schemes is analyzed, including their merits and demerits, moreover, some solutions were given, and which will be the topics of future research.
