Abstract

Content delivery networks are overlay networks that reduce latency by placing a set of servers close to clients. It is specially effective for wide-area networks and the Internet, where network traffic may drive a user to wait for an unreasonable period of time. The approach for such a solution at application layers lacks for optimization techniques at network and data-link layer; from another point of view, it allows a rapid deployment of new applications and protocols, as well as enhancements of current tested ones. This article tries to describe and clarify current work and research in the mechanisms used at the upper-layers of the protocol stack of a content delivery network.
