Video content downloading using P2P approach does not always give good performance though it is scalable. Subscription-based premium services, referred to as cloud downloading have emerged recently. In this service, based on user downloading requests the cloud storage and server caches user interested content and updates the cache. The request is held in a waiting state until the cache is updated, if a requested video is not in the cache. This design is called server mode. An alternative design is to let the cloud server behaving as a helper peer, serve all downloading requests as soon as they arrive.
