Routing Technology of Publish/Subscribe System Based on Subscription Partition

摘要

A routing algorithm based on subscription partition of publish/subscribe is presented in this paper. This algorithm achieves the clustering partition of subscription by the common attribute of subscription predicates' distribution. Each agent manages different subset of the subscription. It greatly reduced the size of the routing table. In order to effectively reduce the number of forwarding events, events and subscriptions are forwarded by the unicast and multicast mixed method. Experiments showed that the algorithm proposed in this paper can effectively reduce the number of agents in the transmission process, and narrow the scope and number of matching operation acted in agent.
