摘要： A method for data integrity check in a network device (2) of a computer network, wherein said network device comprises a communication module (22) and a monitoring module (23), wherein said monitoring module (23) is configured for receiving the same data, which are being received by a communication module (22) from an input port (3001; 3001, 3002, 3003, 3004) of the network device, and wherein the monitoring module (23) receives the same data which the communication module (22) transmits towards one or more output ports (3101; 3101, 3102, 3103, 3104) of the network device, and wherein in case the communication module (22) receives so-called R-data, wherein R-data comprise n data elements, wherein said n data elements are forming an n-tuple, and wherein said R-data are data which the communication module (22) receives from one input port, and wherein said data in its entirety, that is all n data elements of the R-data, are designated to be transmitted by the communication module (22) towards one selected output port (3101; 3101, 3102, 3103, 3104) or towards more selected output ports, the monitoring module (23) receives the same R-data, and wherein the communication module (22) transmits so-called T-data, wherein T-data are data based on the data elements of the R-data received by the communication module (22), towards the output port or towards more output ports of the network device (2), for which output port or ports the R-data corresponding to the T-data are designated, and wherein the monitoring module (23) receives said T-data, and wherein the monitoring module (23)
- derives, after receiving the same R-data as the communication module (22), a sub-tuple of said R-data, a so-called "R-data sub-tuple", wherein said R-data sub-tuple comprises m of the n data elements of the n-tuple of R-data, wherein m > 0 and m
- stores, after deriving said R-data sub-tuple, only said R-data sub-tuple,
- derives, after receiving the T-data corresponding to said R-data, a sub-tuple of said T-data, a so-called "T-data sub-tuple", and
- compares said stored R-data sub-tuple with said T-data sub-tuple, and executes at least one specified or specifiable action, if the comparison of said stored R-data sub-tuple with said T-data sub-tuple delivers as result that said R-data sub-tuple and said T-data sub-tuple are not identical.

摘要： The invention relates to a method and a fault-tolerant computer architecture to improve the performance in fail-safe trajectory planning for a moving entity. The method and FCTA uses a commander, that implements a sensor fusion stage and a trajectory planning stage, and a monitor that implements a sensor fusion stage, and a safe envelope generating stage. Sensors are monitoring the surrounding of the moving entity, and the sensor fusion stages accept sensor data as input. Based on said input the commander and the monitor produce as output real-time images of objects detected due to the monitoring of the one or more sensors. A trajectory planning stage of the commander generates trajectories based on said input, and the said safe envelope generating stage generates a safety envelope based said input. The commander provides the one or more trajectories to the monitor as well as to the decision subsystem.

摘要： A system comprises a plurality of nodes, at least one of the plurality of nodes configured to insert, on a per-virtual link basis, a delay value into a dynamic delay field of a frame corresponding to the respective virtual link, wherein the dynamic delay value represents latency of frames of the respective virtual link. The system also comprises a switch having a plurality of ports, each port coupled to one of the plurality of nodes. The switch is configured to route frames received from the plurality of nodes to one or more of the plurality of nodes. At least one of the plurality of nodes is configured to store frames received from the switch in a buffer and to update the value in the dynamic delay field to reflect the end-to-end system delay.
