Abstract: A solution for managing dates is provided, in which a recurrence definition that represents a list of dates using a recurrence rule is automatically identified. The recurrence definition may also include a set of exceptions, which account for variations from a recurring pattern in the list of dates. In one embodiment, an efficiency measure is obtained for each of various proposed recurrence definitions, and a recurrence definition that most efficiently represents the list of dates is identified. In one application, an event management (e.g., calendaring) program automatically identifies an efficient recurrence rule for a list of event occurrences.

Abstract: A method, article, and system for the dynamic determination of an optimal interval for the generation of a heartbeat signal by a device employed in a system with a dynamic timeout interval.

Abstract: A method to optimize a network connection on a network is disclosed. The method includes opening a socket listener on a device to listen for connections and initiating a first connection from the device to a server through the network. Sending a first message from the device via the first connection instructing the server to attempt to establish a second connection through the network to the socket listener, and determining the network status based upon the success of the second connection. In response to a successful attempt to establish the second connection, closing the first and second connection and maintaining the open socket listener. Following a failed attempt to establish the second connection, sending a second message from the server via the first connection, and closing the socket listener and keeping the first connection open between the device and the server.
