Abstract

A communications protocol interface may be configured as being divisible into a core portion and an extensible portion. The extensible portion of the communications protocol interface may be further configured so that each network element can communicate a unique and optimally small subset of actual interoperable data that corresponds to at least a portion of a larger defined data set. A software generator program may be configured to generate a set of extensible source code that operates upon the subset of actual data and that directs the execution of the extensible portion of the communications protocol interface for a particular network element.

Claims

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,

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.

2. The method of claim 1, wherein the first classification sub-field identifies a particular module within data processing software having an associated set of message types, the second classification sub-field identifies a set of one or more attributes of the first sub-field, and the third classification sub-field identifies a set of one or more additional attributes of the module identified by the first classification sub-field and the one or more attributes identified by the second classification sub-field.

3. The method of claim 1, further comprising transferring control to a communication protocol process operating on the first network device.

4. The method of claim 1, further comprising terminating the communications connection upon receiving a termination communication at the first network device.
