IP网络QoS几种排队算法的对比分析

Comparison and Analysis of QoS Queueing Algorithms Carried out in IP Networks

排队算法是实现IP网络QoS的重要措施之一,文章详细阐述了目前IP网络QoS管理中的三种主流排队算法:WFQ(Weighted Fair Queueing)、CBWFQ(Class-Based WFQ Queueing)、LLQ(Low Latency Queueing),分析了这些算法的基本原理以及发展过程,最后对这几种算法进行了比较,得出了它们各自的优劣特性。

Queueing Algorithm is one of measures which guarantee QoS of IP Network. In this paper, we expatiate on three Queueing Algorithms carded out in IP Networks fashionably： WFQ（Weighted Fair Queueing）、CaWFQ（Class-Based WFQ Queueing）、LLQ （Low Latency Queueing）, analyze the principle of each algorithm and their developed process and compare them at the end.
