Specifications and Architectures of Federated Event-Driven Systems

K. Mani Chandy and Michael Olson

Federated event driven systems (FEDS) integrate event data pushed to it or pulled by it from multiple sites within and outside an enterprise. Performance requirements for these appli- cations can be met by implementing applications on networks of multiprocessors. This paper describes a graph model for applications and a method of mapping the graph on to multiprocessor networks. Information flows among processors within an address space are implemented by passing pointers while information flows across address spaces are imple- mented by message passing. The model and implementation allows an application and the underlying hardware infrastructure to be changed relatively easily. The paper describes an application implemented in this way.
