摘要

在以IP为基础的网络中

IP网络上传送语音（VoIP）成为新一代语音系统的代表

但其业务质量因由IP网络承载而受到限制。多协议标签交换（MPLS）是当前被普遍看好的高速骨干网络技术

通过MPLS

第三层的路由可以得到第二层技术的很好补充

以保证端到端的服务质量（QoS）。将MPLS的QoS特性与区分服务（DiffServ）相结合

可实现更优化的网络业务QoS。

Abstract

In IP-based networks

VoIP has become the representative technology of the next generation voice system

but its QoS is limited by the IP network capacity.Now MPLS is regarded as a most promising technology for high-speed backbone networks.By MPLS

layer 3 routing can be well complemented by layer 2 switching

which guarantees the point-to-point QoS.Network performance can be further optimized by the combination of DiffServ and QoS of MPLS.
