UniGrids Streaming Framework: Enabling Streaming for the New Generation of Grids

We present a new infrastructure for high performance streaming in OGSA/WSRF compliant grid. The UniGrids Streaming Framework (UGSF) works with UnicoreGS as WSRF hosting environment. The paper discusses the advantages of mixed SOAP based control with highly efficient streaming. The UGSF components, streaming server and WSRF web service are described along with a detailed performance analysis including comparison to standard solutions. Some applications based on the UGSF are also presented.
