Method and system for conversion of message formats in a pervasive embedded network environment

摘要

The present invention provides a method and system to convert messages transmitted in a network to a message format that is CAL compliant. In this invention, data conversion points along the network perform data conversions of messages transmitted on the network. These conversion points, known as conversion nodes, can convert routines for the common communication protocols that can convert a message in one protocol to a message in another communication protocol. In the method of the present invention, each time a message is transmitted on the network, the message will pass through one of the conversion nodes before arriving at the state manager. At the conversion node, the message protocol type is identified and the appropriate conversion routine to convert that message format into the compatible format of the destination location of the message. This destination location is normally the state manager. The conversion nodes can be located anywhere along the network, but the most logical at a location where the messages converge, which is near the state manager.
