Abstract

The management of modern distributed systems is complicatedby scale and dynamics. Scalable, decoupled communicationestablishes flexible, loosely coupled componentrelationships, and these relationships help meet the presentdemands on management. However, traditional decoupledaddressing mechanisms tend to focus the addressing on onlyone of the parties involved in communication while, in general,a communication relationship involves a sender, communicatedcontent, and receivers. The state of all three aresimultaneously relevant to correctness of a managementrelationship and its communications. We introduce SelectiveNotification, a scalable, decoupled event disseminationarchitecture supporting simultaneous and combinedaddressing of senders, receivers, and events. We demonstrateits application to programming dynamic, scalablemanagement relationships. We then discuss its implementation,and present measurements of its effective capabilities.
