摘要
简要介绍了IP骨干网络中对QoS技术的定义和其影响因素,并对目前几种比较流行的QoS模型进行了对比。最后重点介绍了DiffServ模型的工作机制,组成部件和相应的实现算法。通过对一些算法的描述,有助于为对从事网质量传输研究或者传输模型实现的相关人员提供一些感性的认识。
Briefly introduced the definition bout QoS technology and some important factors impacting it.Listed and compared three most popular QoS model used in industry,especially for DiffServ model.In last chapter,described the main components in DiffServ model and relevant design Algorithm detailedly to provide useful information for people who worked with or were interested in such kind of domain.
