    摘要: 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.

    摘要: 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.

    摘要: A system and method for time synchronizing nodes in a switch fabric network of a vehicle. The network has a plurality of nodes that are joined by communication links for the transmission of data there between. Each node of the switch fabric may include a processor, a memory, a clock, a transceiver, and an input capture. The memory is adapted to store and retain timer offsets associated with communication links with neighboring nodes. The transceiver is adapted to transmit and receive synchronization messages between the node and neighboring nodes. The input capture is adapted to capture a timestamp associated with the transmission of synchronization messages. The processor is configured to compute the timer offsets associated with the communication links with neighboring nodes based on the captured timestamps by the input capture function. The computed offsets may then be broadcast and stored by the nodes for subsequent use in time synchronizing data packets through the switch fabric network.

    摘要: A system and method for time synchronizing nodes in a switch fabric network of a vehicle. A synchronization request message is transmitted from a requesting node to a neighboring node. At the time the synchronization request message is sent, the requesting node will store a unique message identification associated with the request message as well as a first timestamp that is associated with the time that the synchronization request message was transmitted by the requesting node. The neighboring node will receive the synchronization request message and store a second timestamp associated with the time that the synchronization request message was received by the neighboring node. Thereafter, the neighboring node will transmit to the requesting node a synchronization response message that includes the message identification and the second timestamp. The requesting node will then calculate a timer offset value that is based on the first timestamp and the second timestamp. The timer offset values may then be shared with other nodes in the network so that a summed offset may be used to transmit network messages across a plurality of nodes.

    摘要: A system and method for reprogramming nodes in an automotive switch fabric network using a diagnostic interface. The switch fabric network includes a plurality of nodes joined by communication links for the transmission of data there between. The plurality of nodes includes at least one target node. The target node includes a processor, a transceiver, and a memory. The memory includes an erasable memory portion and a protected memory portion. The processor in the target node switches from executing instructions in the erasable memory portion to executing instructions in the protected memory portion during a reprogramming period when the target node erases a current software component and stores a new software component in its erasable memory portion. The diagnostic interface is adapted to transmit the new software component to the target node.

    摘要: A system and method for evaluating the performance of an automotive switch fabric network using a diagnostic interface. A diagnostic device and interface is connected to an automotive switch fabric network, comprising of a plurality of communication nodes, through one of the nodes in the switch fabric network. The diagnostic device and interface configures the switch fabric network to operate in a test mode. The diagnostic device and interface will issue a first command to one node to start traffic across a test node at a predetermined traffic rate and a second command to another node to generate a test message that passes through the test node. The test node contains message processing logic that will process the messages as they pass through the test node. A plurality of timestamps is generated in the message processing logic of the test node to monitor the progression of the messages through the processing logic. The test node includes a diagnostic interface agent that collects the timestamp data and reports the data back to the diagnostic interface and device.
