Features: This book features innovative material, comprehensive content, and strong systematic organization. It can serve as a professional textbook for senior students in communication, electronics, and computer science programs in science and engineering colleges, as well as a training manual or self-study reference for professional technicians and managers in the telecommunications industry. Next-generation networks are packet-switched networks, and the ability to effectively ensure Quality of Service (QoS) for multi-type services carried by packet networks is the key to the evolution of communication networks toward next-generation networks. This book systematically discusses the QoS assurance issues of packet networks from multiple perspectives. First, it introduces general QoS assurance issues, including basic concepts, technological development, research efforts by standardization organizations, application performance requirements, performance parameters, network performance, and QoS classification, while also presenting a general QoS architecture framework. Second, it analyzes QoS assurance issues in two packet-switched networks (IP networks and ATM networks) and provides an overview of the QoS assurance aspects of other network technologies (such as Ethernet, RPR, etc.). Third, it introduces QoS routing and related traffic engineering methods. Fourth, it covers QoS policy control methods in IP networks and QoS assurance issues in mobile networks. Finally, it analyzes three examples of implementing end-to-end QoS assurance in packet networks. This book systematically collects the latest international research achievements and materials on QoS assurance in packet networks and summarizes the author's extensive experience in communication network research, system equipment research, and overall planning.
