基于质量的互联网内容传输技术（英文版）

　　In this book， we try to illustrate the Internet content delivery mechanism. And based on this mechanism we propose an adaptive content delivery framework which can greatly help Internet Service Providers and Internet Content Providers to achieve quality-based content delivery service. This book can be used as an introduction for Internet content based technology researchers， and can also be used as a reference book for graduate students.This book is the refined wisdom from the Institute of Information Security Engineering， Shanghai Jiao Tong University. We appreciate all of our colleagues for their great help in this book. And we would also express our sincere appreciation towards Shanghai Jiao Tong University Press. Without their help， we would never have this book published so smoothly.
