Abstract: Presently MPLS VPN adopts VPN multiplex model based on two-level label stack toforward packets, which improves the scalability of system but at the same timelimits its ability to provide the strict QoS guarantee to up layer applications.This paper proposes a new approach to support QoS Levels in MPLS VPN, and the main QoS control mechanisms used in the approach are also discussed.
