Requirements for Supporting Customer Resource ReSerVation Protocol (RSVP) and RSVP Traffic Engineering (RSVP-TE) over a BGP/MPLS IP-VPN

Today, customers expect to run triple-play services through BGP/MPLS IP-VPNs. Some service providers will deploy services that request Quality of Service (QoS) guarantees from a local Customer Edge (CE) to a remote CE across the network. As a result, the application (e.g., voice, video, bandwidth-guaranteed data pipe, etc.) requirements for an end-to-end QoS and reserving an adequate bandwidth continue to increase. Service providers can use both an MPLS and an MPLS Traffic Engineering (MPLS-TE) Label Switched Path (LSP) to meet their service objectives. This document describes service-provider requirements for supporting a customer Resource ReSerVation Protocol (RSVP) and RSVP-TE over a BGP/MPLS IP-VPN.
