Chapter 31. MPLS VPN QoS Design Considerations and Recommendations
In addition to the dual role of quality of service (QoS) in the private WAN and branch networks (namely that of managing packet loss and jitter by queuing policies and of enhancing classification granularity by leveraging deep packet inspection engines), the role of QoS over the Multiprotocol Label Switching (MPLS) virtual private network (VPN) may be expanded to include the following:
Shaping traffic to contracted service rates
Performing hierarchical queuing and dropping within ...
