An apparatus comprising: an input for receiving a stream of data transmission units; a filter configured to identify data transmission units of a first predetermined type based on predefined identifying information and generate a second stream of data transmission units comprising said first stream with at least one data transmission unit filtered out; a protocol module configured to identify, based on second predefined identifying information, and in said second stream at least one data transmission unit of a second predetermined type and add protocol information thereto; and wherein the filter being configured to filter out said at least one data transmission unit provides time in said second stream for the addition of the protocol information; and wherein the apparatus includes a transceiver configured to output signals representative of said data transmission units of the second stream with said protocol information added to a transmission medium.

Apparatus including a transceiver

Embodiments of a device and method are disclosed. In an embodiment, an Ethernet communications device includes a physical layer (PHY) unit or a media access control (MAC) unit configured to perform media access control for the Ethernet communications device. The Ethernet communications device includes a security unit configured to manipulate a data stream in a data path within the Ethernet communications device when the data stream violates or conforms to a pre-defined policy.

Ethernet communications device and method for operating an ethernet communications device

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.
