Class-based QoS defines traffic classifiers based on certain rules and associates traffic classifiers with certain traffic behaviors, forming certain traffic policies. After these policies are applied to interfaces, class-based traffic policing, traffic shaping, congestion management, and precedence re-marking are implemented.
The Huawei NE40 router / NE80E supports DiffServ and provides standard forwarding services such as EF and AF for users by using the following traffic management measures:
1 Traffic classification
2 Traffic policing
3 Traffic shaping
4 Congestion avoidance
QoS of the NE80E/40E supports traffic policy with the above measures and mapping between the QoS fields in the IP header and the MPLS header.
The traffic policies in the NE80E/40E are as follows:
