队列管理算法对VOIP QoS的提高

摘要

Voice over IP (VoIP) has become increasingly popular over the IP network, Nevertheless, these real-time traffic may experience less than desirable quality, and the performance is unsatisfactory particularly when the link is congested. This paper presents a method of improving the QoS of real-time audio over IP network infrastructure at low service cost and with no changes to the existing network. A thorough study of RED' s effects on voice over IP is given, concluding that RED is able to control the delay distribution, jitter and effective loss of VoIP.%VoIP日益成为受用户欢迎的IP网络服务,然而,这些IP网络上的VOIP通话质量却并不能得到令人满意的保证,尤其是当网络拥塞的时候.文中提出了一种不涉及改造网络结构,低成本地提高VOIP的通话质量的方法.通过随机早期检测算法的应用,可以有效地降低VOIP通话的延迟、抖动和有效丢包率,从而提高VOIP的通话质量.
