摘要
尽管增加带宽能够改善因特网的服务质量,但简单地增加带宽无法满足新应用的特点与需求,因此需要为目前“尽力而为”的IP网引入服务质量(QoS)技术。IETF目前看好两个IP QoS标准:区分服务(DiffServ)和MPLS。文章研究了它们的特点、区别以及MPLS支持DiffServ的技术。
Internet services may be improved by increasing bandwidth. At the same time, there is the need to introduce QoS technology into present “best effort”IP networks. IETF currently prefers two IP QoS standards, namely DiffServ and MPLS. The characteristics and the difference between these two standards are introduced in this paper. Besides that, the technology for MPLS to support DiffServ is introduced.
