And L3 MPLS Virtual Private Network (VPN) is based on the MPLS implementation, so you can use the quality of service-based traffic engineering and MPLS DiffServ mechanism to protect the business.
In this paper, combining network security, we discuss the theory and technology of traffic control, design and implement the traffic control based on DiffServ.
Previous proposals such as IntServ, DiffServ, and IP Multicast have not seen wide acceptance largely because they require modification of all routers in the network.
This field is now defined by RFC 2474 (updated by RFC 3168 and RFC 3260) for Differentiated services (DiffServ). New technologies are emerging that require real-time data streaming and therefore make use of the DSCP field.
Hierarchical QoS scheduling and traffic shaping DiffServ mode based on traffic classification Simple traffic classification, complex traffic classification, per hop behavior (PHB), and ACL Committed access rate (CAR) PQ scheduling priority, weighted fair queuing (WFQ) and PQ+WFQ queuing Tail drop and weighted random early detection (WRED) Eight priority queues Shaping based on port scheduling priority

A differentiated service (DiffServ) model is proposed to support end-to-end differentiated services, and several function terms are explained in detail.
This method, on the one hand, avoids collision and provides quantitative per flow QoS guarantee, on the other hand, keeps DiffServ scalable without any per flow management on core routers.
