A scalable content delivery network (SCDN) employs a parallel download mechanism to ensure that a demanded file is present at a station in time for user consumption. This mechanism is used in solving the content caching and storage problem for applications such as video-on-demand, which is commonly perceived as a tough problem in the industry. In the network, files are divided into smaller units called tracks according to the nature of data contained in each of them. Tracks are further divided into smaller equally sized units called block files. This division builds the foundation for parallel download. A sequence server provides a lock-free mechanism for multiple threads or processes to access data atomically.
