Abstract
A system and method for streaming sequential data through a vehicle switch fabric network. This is particular useful in areas such as reprogramming nodes in the automotive switch fabric network where relatively large records or messages need to be transmitted through the switch fabric, although the invention may be used in other areas. In sum, the system and method described herein takes large data records and breaks them down into smaller units (data packets) that fit within the constraints of the physical layer on which communication links in the switch fabric network is built. The smaller data packets are assigned with a message identification and a sequence number. Data packets associated with the same data record or message are assigned with the same message identification but may differ in their sequence number. Each data packet is transmitted over the vehicle switch fabric network to a destination node. At the destination node, the data packets may be reassembled to its original data format based on the message identification and sequence numbers. The reassembled message may then be presented to an application in the node for processing.
