Abstract: A proxy slave in a first LIN partition receives data from a proxy master in the second LIN partition which in turn receives the data from a slave in the second LIN partition. The proxy slave stores the data in a data structure and receives a read request from an originating master in the first LIN partition after the data is stored. The read request comprises a LIN message identifier subscribed to by the slave in the second LIN partition. The proxy slave accesses the data stored in the data structure based on the LIN message identifier in the read request; and sends a LIN response to the originating master with the stored data from the slave in the second LIN partition.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a physical layer (PHY) device that is compatible with the IEEE 802.3 standard and that utilizes carrier-sense multiple access with collision detection (CSMA/CD) for media access control to a shared media is disclosed. The PHY device includes a physical coding sublayer transmitter (PCS-TX), a physical medium attachment transmitter (PMA-TX), a physical coding sublayer receiver (PCS-RX), a physical medium attachment receiver (PMA-RX), and a media access priority manager configured to initiate transmission of an indication of a priority of a frame that is to be transmitted onto the shared media.

Abstract: Embodiments of a method, a device and a computer-readable storage medium are disclosed. In an embodiment, a method for controlling access to a communications medium involves replenishing a credit value assigned to a communications node in a communications round, granting or denying access to the communications medium to the communications node during the communications round based on the credit value, and controlling the credit value in response to granting or denying access to the communications medium to the communications node during the communications round.
