Li Huan · Jisuanji yingyong yanjiu · 2004
As we all know, CDN became a technique for soluting the network traffic and bandwidth bottleneck. Existing work on CDNs has primarily focused on techniques for efficiently redirecting user requests to appropriate CDN servers to reduce requestlatency and balance load. In this paper, a dynamic programming approach and a greedy placement algorithm are given, in the situation which proxy is capacitated and budget is limited, and the goal is to minimize the network bandwidth consumption.
