内容简介
《基于质量的互联网内容传输技术(英文版)》内容简介：Qua\ity-Based Content Delivery over the Internet mainly discusses themethodology of doing quality-based content delivery in an Internetenvironment. Because the network is becoming intelligent and active, moreand more researchers are talking about achieving personalization andcustomization in Internet content delivery. As researchers are aware, byintroducing intelligence into a web intermediary server, they can make thecontent delivery more efficient and of higher quality. Still, the detailedmethodology of doing so is never illustrated fully. The most critical part willbe the active content transformation model. "[his book gives a detaileddescription of the active content transformation model, and providesexperiments and data to show its feasibility. Some examples of how to doefficient content transformation in active web intermediarv to achieve highquality are also presented to help understand the whole process.The book is an introduction and excellent reference for researchers in theInternet content delivery area.
