End-to-End MPLS HQoS Solution

Figure 9-12 Implementing end-to-end QoS in L2VPN

On the CE-side interfaces of PEs, interface-based QoS policies are configured to implement QoS enforcement on packets that are received from CEs or sent to CEs.

On the ingress PE that is, PE1, QoS policies are configured based on VLL/VLL instance + peer PE for packets that are sent to the public network side. Besides, to deliver end-to-end QoS guarantee for traffic, the TE tunnel that is allocated bandwidth can be adopted to carry VLL traffic. In addition, on PEs, QPPB can be configured to propagate QoS policies, and the MPLS DiffServ model can be configured so that in MPLS VPN services, both the private network and the public network that are configured with the DiffServ QoS model can communicate.

On the P node, QoS policies are enforced based on interface/TE tunnel without distinguishing between VLL services and non-VLL services.
