    abstract =  {This document presents a quality of service (QoS) framework for IP based virtual private networks (VPNs). For IP based VPNs to provide a service comparable to private line networks it has to provide a number of features including closed user groups, security and performance guarantees. This document focuses primarily on the issue of performance, and provide a QoS framework which is applicable to various VPN solution that have been proposed.},
