Event distribution middleware supports the integration of
distributed applications by accepting events from information producers
and disseminating applicable events to interested consumers. We present
a flexible new model, the Information Flow Graph (IFG), for specifying
the flow of information in such a system. We illustrate the use of the
IFG for: content-based publish/subscribe; stateless event
transformations that consolidate events from diverse sources; and
stateful event interpretation functions for deriving trends, summaries,
and alarms from published events and for defining equivalent event
sequences. We introduce two techniques for efficient implementation of
such systems: a flow graph rewriting optimization which allows stateless
IFGs to be converted to a form which can exploit efficient multicast
technology developed for content-based publish/subscribe system; and an
algorithm for converting a sequence of events to the shortest equivalent
sequence of events with respect to an event interpretation
function
