7.1 Introduction
When network applications become more and more versatile, users bring forward different
Quality of Service (QoS) requirements on them. In this case, the network should distribute
and schedule resources for different network applications as required. When network is

Service model
Priority trust
Traffic classification
Traffic policy
Priority mapping
Congestion management
