Replication and notification management in a knowledge delivery network

Knowledge delivery networks are slowly becoming the foundation behind the day-to-day operations in information-intensive industries. This paper attempts to highlight some central management problems facing these networks, especially for voice/telephony-based interaction. We present the concept of a knowledge delivery network and identify the data structures and its basic architecture. Using an overlay technique, we implement the knowledge network over an existing data network infrastructure. The knowledge network moves (replicates) information using XML-formatted packets that are processed in every node, drawing from principles encountered in active networks. We describe the management problems encountered in such networks, and focus in particular on replication strategies, and notification delivery.
