    摘要： Nodes which include additional sensing and communication capability as compared to prior nodes. The sensing capability allows determination of actual current flows through the particular nodes, including each port of the node, to allow a determination of power flow to better control operations. Because of this understanding of power flow, smaller modules or nodes can be utilized if desired. For protection of a lower power node, an upstream node can open the link to the node should it go overcurrent or otherwise fault. Further, with the additional sensing capability, actual load balancing and multiple controllable flows, such as for standby, can be developed. The additional communication in combination with the sensing also allows better fault isolation. By being able to determine the actual location of the fault, other operations in the vehicle can continue with just the faulty area being disconnected.

    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 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.

    摘要： A vehicle network and method for communicating information within a vehicle. The network includes a plurality of network elements joined by communication links. A data frame is provided for communicating information between a first device and a second device attached to the network. A network element in the network is capable of mapping a first resource on an incoming communication link of the network element to a second link resource of an outgoing communication link of the network element. The network element further has ports for receiving the data frame from the first link resource of the incoming communication link and for communicating the data frame to the second link resource of the outgoing communication link. The mapping may be done statically or dynamically such as based on information stored in the network element or based on information stored in the data frame.
