Abstract
A system and method for tunneling standard bus protocol messages through an automotive switch fabric network. When a bus protocol message arrives on a connecting node in the network, a bus driver in the node will capture the message and store it into a message buffer where the message can be further processed by a tunneling application. Each received bus protocol message will be broken, or combined, to suit the available packet size of the underlying transmit layer of the switch fabric network. Data portions such as message identification, sequence number, port number, bus data type, and data length are reserved in each data packet. If the message is being broken down, the sequence number is used to differentiate the broken segments of the bus protocol message. The bus data type is used to indicate the type of protocol data being transmitted over the switch fabric. The same tunneling application may be used to reassemble the bus protocol message at a receiving node.
