Abstract:

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 QoSS 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 mmust be provided in the MPLS VPN. So we propose Q-DVPN,which is the QoS Dynamic VPN,and give the corresponding solutions.

Key words: Q-DVPN, QoS, MPLS, VPN, BB
