Abstract

A reliable event delivery system for use in a distributed event driven system in which one or more servers are each connected by a reliable communication transport system to a client station. Each server communicates event messages over a reliable transport system to the client station for execution. Receipt of the event messages at the client station transport protocol level is guaranteed by the reliable transport system. Guaranteed delivery at the client station's event execution level is achieved by the client station providing an event execution acknowledgment to the server. Another embodiment provides for secure and reliable event delivery by using a second transport system for use by the client station for requesting a confirmation from a server that an event message received over the first transport system was sent from the server and intended for the client.
