Abstract
A method and apparatus for controlling bandwidth in a Virtual Private Network assigns and allocates transmission bandwidth to packet VPNs for either connectionless or connection-oriented communication. The method creates two views of transmission facilities: a user plane view and a control plane view. In the user plane view, the bandwidth of the transmission facility is split into quantified and identified partitions. In the control plane view, transmission facilities are represented as logical links forming a topology that can be used for the purpose of routing the VPN. The two views are tied together by assigning user plane partitions to VPN control plane links. As a result, the allocation of bandwidth to VPNs becomes a controllable and viewable entity, thereby facilitating management and QoS provisioning in a VPN network.
