<p>A system and method for event notification and access control for Distributed Hash Tables (DHTs) using an event triggering mechanism for DHT-based Peer-to-Peer (P2P) overlay networks is described. According to an embodiment of the invention, a user interested in certain event can insert a trigger into the DHT. When the event occurs, the trigger fires and causes a pre-defined action to be executed. According to another embodiment of the invention, a user peer inserts a trigger resource record, which includes instructions to execute a specified action upon occurrence of the event, into the DHT. A monitored resource record, with which the event is or will be associated, is identified. A monitoring peer, responsible for maintaining the monitored resource record, is then identified. The trigger resource record is maintained at the monitoring peer.</p> |
