US Patent 6839731 System and method for providing data communication in a device network

A system and method for facilitating data communications in a device network are provided. An integrated information system includes a number of premises-server computing devices, a central communication device, and a number of client computing devices. Each client computing device communicates with the central communication device to request access to device data from the premises-server computing devices. Once access rights are established, the client computing devices communicate directly with specific premises-server computing devices. A command application resident on each premises-server computing device, referred to as the command proxy, administers the direct flow of data between the computing devices.
