Storage server requirements for delivery of hypermedia documents

Current approaches for continuous media (CM) file systems focus on scheduling requirements for sessions consisting of single video or audio streams. This paper examines the multimedia delivery problem from the perspective of hypermedia document servers. Such hypermedia documents can be characterized as a web of nodes, each node containing a set of time-dependent CM and discrete media objects. We first look at a hypothetical user’s view of a hypermedia session. We then present two service models, the CM service model and the hypermedia service model, and compare them.We propose a new view of session, a hypermedia session, suitable for scheduling the delivery of hypermedia documents, and present sample scheduling algorithms. This notion of hypermedia session is examined from the standpoint of resource management at the orchestration layer of distributed MM system.
