1. A method of establishing a communications connection between network devices comprising: creating an interchange envelope comprising: a connection request at a first network device, a set of information addressed to a medical object management protocol layer defining grammar or rules used to build common sentence structures to communicate medical data, and a rendezvous protocol connection request message identifier, transmitting the interchange envelope to a second network device, receiving a response to the connection request from the second network device, creating an encryption key request for the second network device, transmitting the encryption key request to the second network device, receiving an encryption key in response to the encryption key request, creating a start communication protocol process request for the second network device, transmitting the start communication protocol process request to the second network device, receiving a host ready communication in response to the start communication protocol process, and wherein each request and response is classified and processed based upon a first classification sub-field, a second classification sub-field, and a third classification sub-field within each request and response.
