摘要：

Content delivery over the Web has become an important element of improving web performance. Content delivery Networks (CDN) has been proposed to maximize bandwidth, improve accessibility, and maintain correctness through content replication. CDN reduce the customer's need to invest in website infrastructure and decrease the operational costs of managing such infrastructure, bypass traffic jams on the web and reduce the load on origin servers. CDN topology is built such that the client-perceived performance is maximized and the infrastructure cost is minimized. CDN maintains a mapping between content and surrogate servers, and each request is directed to the closet surrogate server. Data mining techniques offer an effective benefit for CDN, since CDN manage large collection of data over highly distributed infrastructure. CDN is still in early stage of development and is essential to understand the existing practices involved in a CDN framework in order to predict evolutionary steps.
