Abstract

The present invention presents a “serverless” medical information system network and method of creating one or more self-assembling and self-monitoring medical device network grids. Several communication node devices form each grid. Each node device may connect to one or more medical instruments, providing the medical instruments access to the network. The invention also includes methods for assembling the tree-like structure of the grid and balancing the load or placement of the nodes across the entire grid and for self-monitoring of the grid, such that the nodes can detect, record, and distribute changes to the status of any node in the grid. In addition, the nodes can provide web services to other computer devices, such as handheld devices.

sending the request message, via a TCP/IP connection, to a computing device that can provide name service over a plurality of the grid segments; and

the computing device sending the request to a plurality of connected nodes on a plurality of grid segments.

20. ) A method according to claim 16, wherein the step of receiving comprises receiving an IP address and a domain name from one of the connected nodes in the one or more grid segment.

21. ) A method according to claim 20, further comprising:
