VCDN: A CONTENT DISTRIBUTION NETWORK FOR HIGH QUALITY VIDEO DISTRIBUTION

Content Distribution Networks (CDNs) have aided web servers in dealing with hot spots by replicating popular content on servers close to the clients. Typical CDNs are static in nature and as such, do not be able to react well with changing client viewing trends. This paper outlines the design of a Video Content Distribution Network (VCDN), which unlike tradition CDNs, is designed to automatically replicate and/or move content on to proxies located closer to the clients generating the requests. This paper outlines the costs involved in the system and the proposed algorithm for content placement and replication. The placement algorithm monitors client locations and server load on an ongoing basis, and alters the set of serving proxies and/or content location to minimize the overall resources being used. As a result of this, the VCDN is expected to yield near optimal cost effective video distribution.
