摘　　要：VPN可以使企业能够在Internet上既安全又经济地传输私有信息。MPLS的优点可以在建构VPN中得到充分利用和体现,而服务质量问题是现在网络研究的热点。结合针对基于MPLS的网络的流量工程(DS-TE)技术,可以很好地实现服务质量的保证和细化。因此将其应用于MPLS/VPN的组网中,这更有利于实现VPN配置和管理上的简洁化和智能化。The advent of VPN makes it possible for enterprises to transform private message securely and economically via the Internet. The advantage of MPLS is made good use of and embodied in constructing VPN, and the problem of Qos （quality of service） is a new hot spot in network study nowadays. The technology of DS-TE （diffserv-aware traffic engineering） to aim at the Interact based on MPLS help to achieve the guarantee and specific in a much better way. Therefore, the application of this technology to MPLSNPN will contribute to carrying out the collocation of VPN and will make the management more simple and intelligent.
