Taking the step from meta-information to communication middleware in computational data streams
Beth Plale, Patrick M Widener, Karsten Schwan · 2005
It is our belief that network applications relying on globally distributed shared resources will increasingly adopt meta-level descriptions to describe the data streaming in the application at runtime. Our group has developed the notion of computational data streams to describe and act upon such data flows. Our work conceptualizes the data flows as database relations over which useful operations, such as querying, can be performed. This paper shows how one can make the step from a meta-level description of data flows to an actual implementation using CORBA-style event channels and binary I/O for data transport. 1
