An Integrated Approach to Scalable Content Delivery over the Internet

该项目将调查为快速增长的用户群体提供更好的网络信息和服务访问的问题。我们的目标是通过对内容分发网络中的架构、问题和性能问题进行系统的研究，朝着可伸缩性迈出下一步。将探索减少响应时间和网络负载的新方法。采用集成的方法来研究内容分发系统中不同组件的协同效应。具体包括动态内容分发技术的研究、应用层组播分发协议的设计、动态服务器选择算法的研究和动态副本放置方法的研究。

This project will investigate the problem of providing better access to web information and services to a rapidly growing user population. The goal is to take the next step toward scalability by performing a systematic study of architecture, problems, and performance issues in content distribution networks. New ways to reduce response time and the load imposed on the network will be explored. An integrated approach is adopted to study the synergetic effect of different components in content distribution systems. Specifically the researchwill include developing dynamic content delivery techniques, designingapplication-level multicast delivery protocols, developing dynamic server selection algorithms, and studying dynamic replica placement methods.
