虚拟专用网(VPN)中QoS的研究与实现

The Research and Realization of QoS in Virtual Private Network (VPN)

随着网络规模的迅速扩大,用户对专用网络的需求越来越大,虚拟专用网为用户提供一个安全和低费用的环境,但其服务质量(QoS)是一个非常重要的因素。首先对VPN中的QoS问题及其研究现状进行了综述,然后着重分析了InterServ和DiffServ两种模型的QoS实现框架研究,并进行了比较分析;其次对基于MPLS技术的VPNQoS进行了分析。

With the rapid enlarging of network , The requirement of private network is ever-enlarging, Virtual Private Network provides an environment of security and low cost, but the Quality of Service （QoS） is a very important factor. First give a detail narration for the question of VPN QoS and research state, then analyses the implement of QoS frame research with InterServ and DiffServ model, also analyses the VPN QoS with MPLS.
