4.1 Introduction
User brings force different service quality demands for network application, then network
should distribute and schedule resource for different network application according to user
demands. Quality of Service (QoS) can ensure service in real-time and integrity when
network overload or congested and guarantee the whole network runs high-efficiently.
QoS is composed of a group of flow management technology:

Service model

Priority trust

Traffic classification

Traffic policy

Priority mapping

Congestion management
4.1.1 Service model
QoS technical service models:

Best-effort Service

Differentiated Services (DiffServ)
