Abstract
Provided is an event delivery system where a bottleneck on the system can be eliminated by reducing load on a rendezvous node. The event delivery system includes publisher nodes, subscriber nodes, the rendezvous node, and broker nodes. The rendezvous node includes a traffic monitoring means that monitors the traffic volume of event information issued by the publisher node, and a specific event determination means that determines specific event information subject to load distribution from among the event information when the traffic volume exceeds a predetermined value. Each broker node includes a route defection means that detects whether its own node is an aggregation point node or a branch point node of the delivery route of the specific event information, and a route construction means that constructs a new delivery route of the specific event information going through the aggregation point node and the branch point node, bypassing the rendezvous node.
