Embodiments of the present invention analyze multiple factors—such as user input events, device motion data, other data from the endpoint, or data from an external system (such as a real-time location system)—to make a probabilistic determination whether a walkaway event has occurred.

Inference-based detection of proximity changes

Embodiments of the present invention analyze multiple factors&#x2014;such as user input events, device motion data, other data from the endpoint, or data from an external system (such as a real-time location system)&#x2014;to make a probabilistic determination whether a walkaway event has occurred.

A communication system in which client and server communication systems are coupled over a data network. A request to communicate with one of the server communication systems is accepted and based on an identification of the server communication system in the request, one of a set of transport layer protocols is selected for communication between the client and server systems. The set of transport layer protocols can be determined by retrieving information from a directory service computer, such as an Internet Domain Name Server (DNS), where the address of the directory service computer is related to the identification of the server communication system. In addition, the server communication system can include an address translation table that associates a network address provided by a client communication system with local network addresses of server computers. The server communication system selects one of the server computers in response to a request from the client communication system and passes communication between the client system and the selected server computer.

Enhanced network communication

When establishing a communication path between a client system and a server system which are coupled over a data network, the client system accesses distributed directory information in order to determine whether a communication path to the server computer can use an enhanced communication approach, such as an enhanced transport or application layer protocol, and to obtain an address of a second server system which will provide communication services needed to communicate using the enhanced communication approach. By using distributed information, and in particular by distributing the information at the server systems themselves, the invention reduces or eliminates the reliance on critical points of failure or congestion, such as a Internet Domain Name Server (DNS) or a centralized repository of information related to the enhanced communication.
