Title: Event-triggered notification over a network

Abstract: Internet services that rely on the transfer of real-time information have proliferated in recent years. Given the amount of information generated on the Internet, a user may request to be notified whenever particular information becomes available, such as the current highest bid in an on-line auction. The user enrols to receive one or more messages and sends a list of desired messages through a client process running on the user's computer system. When the user is ready to receive messages, the client process connects to a notification server and provides its receiving address identifier. It then disconnects from the notification server and waits for messages. A message monitor detects the occurrence of events that trigger notifications, and informs the notification server of the event. The notification server determines the appropriate recipient for the notification, and sends it using a server-initiated end-to-end message transfer mechanism to the clients' receiving address identifiers. The notification can also be used as a control signal to control one or more applications, or to control an appliance remotely over a network. The notification server may make use of load-sharing devices or proxy servers to distribute the notification to the client processes.
