Abstract: A method for validating a data packet in a communication network of a platform are provided. The method comprises receiving a data packet at a physical layer device of a first node in the communication network, accessing data stored in a data register of the first node, the data comprising a copy of data stored in a data register of a second node in the communication network, the data comprising a physical layer representation of an instruction to execute at the first node and determining the validity of the data packet on the basis of the data. The instruction is determined on the basis of sensor data received from one or more platform sensors in communication with the second node.

Abstract: Provided is a sensor (100, 202) for use in an in-vehicle network (104, 200, 300), for communicating with at least one other unit in the in-vehicle network by means of packets through a switch (102, 204, 400). The sensor is being arranged to create sensor-specific traffic information indicating at least one configuration parameter to be used for transmitting packets to or from the sensor, and communicate the sensor-specific traffic information to the switch. The traffic information is being based on the type of sensor and on context data indicative of a current traffic situation.

Abstract: A communication interface for use at a first end of a communication link includes a number of communication lanes. The communication interface includes a logic configured to cooperate with another communication interface at a second end of the communication link to send data to the second end over the communication lanes. The logic is configured to store a communication lane status for an awake communication lane and when detecting that the communication lane status for the awake communication lane is changed to a first determined status. The logic is configured to stop sending data over the awake communication lane, and change an asleep communication lane into a new awake communication lane, and inform the communication interface at the second end. The communication interface provides a seamless and asymmetric data communication between the first end and the second end of the communication link, even in case of a lane failure.

Abstract: A communication interface for use at a first end of a communication link including a number of communication lanes greater or equal to two. The communication interface includes a logic configured to cooperate with another communication interface at a second end of the communication link to send a data frame to the second end over the communication lanes. The logic is configured to store a communication lane status for each of the communication lanes, and when detecting that the communication lane status for a specific communication lane has changed to a determined status. The logic is configured to send the changed communication lane status for the specific communication lane to the communication interface at the second end and split a data frame accordingly. The communication interface provides seamless data communication between the first end and the second end of the communication link, even in case of a lane failure.
