Abstract: The embodiments described herein present methods and apparatuses for on-path CAC operations in a MPLS-VPN environment. In an example embodiment, an ingress PE device receives a quality of service (QoS) resource reservation request; constructs an outgoing message that includes information allowing an egress PE device to identify the virtual private network routing and forwarding table (VRF) associated with a resource reservation resulting from the QoS resource reservation request; and transmits the outgoing message to the egress PE device, where the information allowing VRF identification is echoed back by the egress PE device and used by the ingress PE device to identify the VRF associated with the resource reservation resulting from the QoS resource reservation request. Other embodiments are described.
