为了提高lP网络的QoS,以达到电信级的服务质量要求,MPLS技术可实施全网流量工程,支持QoS保证的各种传输业务,为此IETF提出了两种基本模型即综合业务模型和分类业务模型,而后者更被看好。本文从MPLS技术手入,阐述了分类业务模型及利用MPLS技术入手,阐述了分类业务模型及利用MPLS传输和实施分类业务的方法。
In order to improve the QoS of the lP network in order to achieve carrier-class QoS requirements, MPLS technology can implement the whole network traffic engineering and support various QoS-guaranteed transmission services. Therefore, the IETF proposes two basic models, that is, an integrated service model and a classified service Model, while the latter is more optimistic. This article from the MPLS technology into hand, described the classification of business models and the use of MPLS technology, described the classification of business models and the use of MPLS to transport and implement classified services approach.
