服务质量动态VPN(Q-DVPN)及其解决方案研究

Research of Qos-Dynamic VPN and Its Solution

随着网络技术的发展和网络应用的多元化,VPN客户、VPN所承载业务数据种类、VPN客户对资源使用的要求都趋向多元化。如果VPN网络基于MPLS网络来构建,就能迎合VPN日益发展的各方面的QoS要求。文中指出,为了充分利用MPLS网络的QoS机制,必须在MPLSVPN中提供使用Qos机制的接口机制。据此,我们提出了Q-DVPN即服务质量动态VPN这一全新的概念,并随之给出了相应的解决方案。

With the development of network techniques and the diversification of network applications, diversification also happens in customers, data types and ways to use the resources of VPN. If a network is built based on the MPLS VPN network, it will be able to meet the growing VPN＇s various aspects of QoS requirements. This paper also points out that to take full advantage of the MPLS network＇s QoS mechanism , the mechanism of using the QoS mechanism must be provided in the MPLS VPN. So we propose Q-DVPN,which is the QoS Dynamic VPN,and give the corresponding solutions.
