Specifications and Architectures of Federated Event-Driven Systems ∗

Federated event driven systems (FEDS) integrate event data pushed to it or pulled by it from multiple sites within and out-side 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 mul-tiprocessor networks. Information flows among processors within an address space are implemented by passing point-ers while information flows across address spaces are imple-mented by message passing. The model and implementation allows an application and the underlying hardware infrastruc-ture to be changed relatively easily. The paper describes an application implemented in this way
