IP网络接纳控制研究评述

The 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。这些接纳控制机制在一定程度上都能满足QOS的需求,但也不同程度地在诸如可伸缩性、健壮性等方面存在一些问题。本文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 components of the implementation of IP networks' 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 etc. In this paper,the fundament of a few admission control schemes is analyzed,then their merits and demerits are analyzed,moreover,some solutions are given,and which will be the topics of futural research.
