Data streaming requires some combination of bandwidth sufficiency and, for real-time human perception of the data, the ability to make sure that enough data is being continuously received without any noticeable time lag. (SearchNetworking.com)

Efficient and robust data streaming services are a critical requirement of emerging Grid applications, which are based on seamless interactions and coupling between geographically distributed application components. (Portal)

A practical data streaming service must, therefore, be largely selfmanaging, i.e., it must dynamically detect and respond, quickly and correctly, to changes in application behaviour and state of the Grid. (A Self-Managing Wide-Area Data Streaming using Model-based Online Control)
