A Policy-Based Mixed Publish/Subscribe Message Exchange Pattern Used for Traffic Monitoring System

Abstract:

Pub/Sub message exchange pattern (PSMEP) is a flexible and effective message exchange pattern, by which various components in a large-scale distributed system can be linked together organically and interact with each other in a loosely coupled environment. There are two PSMEPs in traditional Pub/Sub model: topic-based pattern & content-based pattern. Topic-based pattern is elegant and efficient, but not flexible to make subscription; while content-based pattern is flexible enough, but is not efficient. This paper proposes a policy-based mixed PSMEP to make up the deficiency of the two patterns, and a simulation in traffic monitoring system introduced in this paper will proof the policy-based pattern is effective.
