Policy-based Management of Semantic Clustering

Abstract

We introduce the concept of a Knowledge-based Network KBN [1] as an extended Content-based Network (CBN), where semantically rich messages co-exist with the more traditional CBN messages format. One of the main advantages this new technology, a KBN, is in its ability to define subscription filters across the semantics of the contents of messages, in addition to the commonly available, traditional, CBN filters. Knowledge-based Networks (KBN) support the routing of semantically enriched messages between interested parties across a common network of message brokers. Knowledge-based Networks introduce an unprecedented level of semantic richness, which allows semantic clusters of publisher/subscriber to form within a KBN creating pockets of focused interest. When this is exploited direct performance increases can be seen [1]. We propose a flexible policy-driven mechanism to manage the future semantic clustering of Knowledge-based Networks.
