An Integrated Approach to Scalable Content Delivery over the Internet

这个项目将调查如何为快速增长的用户群体提供更好的网络信息和服务。我们的目标是通过对内容分发网络中的体系结构、问题和性能问题进行系统的研究，向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。采用综合方法研究内容分发系统中各组成部分的协同效应。具体而言，研究将包括开发动态内容传递技术，设计应用级多播传递协议，开发动态服务器选择算法，以及研究动态副本放置方法。

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.
