摘要：
This paper analyzes the problems of IP networks when transmitting real-time business, and describes the overall function of QoS (Quality of Service) technologies, these technologies aim to improve the quality of service IP networks. Then, we focuses on the famous service models which can meet the QoS requirements, proposed by Internet Engineering Task Force (IETF), including Integrated Services model (IntServ), Differentiated Service model (DiffServ), Multi-Protocol Label Switching (MPLS), Traffic Engineering (TE) and Constraint-based Routing, analyze their advantages and disadvantages, and then study the relationship between them. Finally, we conclude that, integrated use of various models based on MPLS is the most promising technology to provide QoS guarantee, in large IP networks.
