Delivery route building program load balancing method event distribution system, the rendezvous node, broker node, the event distribution system, load balancing method of rendezvous node, route delivery method for constructing a broker node, and load balancing program,

摘要

And an object thereof is to provide an event delivery system which can eliminate bottlenecks in the system by reducing the load on the rendezvous node. The event distribution system according to the present invention, includes publisher node, subscriber node, the broker node and rendezvous node, and traffic monitoring means for monitoring the amount of traffic event information publisher node has outgoing, rendezvous node, given the amount of traffic and a, and specific events determining means for determining a specific event information on which to perform load balancing among event information when it exceeds the value, the own node, broker nodes, aggregation of delivery route of certain events, information and a route building means to build a root detection means for detecting whether a branch point or node point node, a new delivery route of the specific event information via a branch point node and aggregation point node, to avoid the rendezvous node have.
