Survey of Publish Subscribe Event Systems

(May 2003), 19 pages
The Internet has changed considerably the scale of distributed systems, motivating the demand for more flexible communication models and systems. Individual point-to-point and synchronous communications, which tend to lead to rigid and static applications, are making way for the more loosely coupled interaction such as is supported by a publish-subscribe paradigm.

In this paper, we define a taxonomy for comparing and contrasting publish subscribe systems, citing examples from the systems included in the survey. We then survey existing publish subscribe systems, and discuss their features with respect to the taxonomy. The appendix contains a code example that demonstrates use of a typical publish subscribe system.
