Title:
Accelerating Composite Event Processing with Dynamic Subscription
Abstract: The concept of complex event processing is proposed
by Prof. David Luckham, Harvard University. The goal of complex event processing
is, in the distributed environment, to enable the system to communicate,
coordinate, analysis the events that may be related to one another with time
or context. This paper focuses on improving the effectiveness of the original
architecture by adding the active mechanism into the system. The benefit
of this mechanism includes: reducing unnecessary data processing and the
saving of computing resources and network bandwidth. The second section of
the paper introduces the researches and articles including: First, the concept
of context-awareness. Second, the similarities and differences between the
event-driven architecture and the service oriented architecture. The third
one is the on-going architecture and the mechanism of the CEP. The
third section proposes the new architecture of the CEP with the active subscribe
/ unsubscribe mechanism. This section includes the motive of the active mechanism,
the system architecture, the procedures and system flows and the newly added
components. The fourth section is the scenario of identifying suspect cases
of SARS patients. The benefit of the new architecture is illustrated and
discussed. The final section is the conclusion and some future improvements
of the system.
