Abstract
A network device for a computer network (1), the network device (2) including communication channels (3), a PHY chip (4) configured for transmitting data in a raw data stream on the communication channels, and a MAC chip (5) configured for encapsulating data to be transmitted into frames, and for calculating a checksum for each frame. The PHY chip is configured for receiving frames of the MAC chip and transmitting transmission data contained in the frames via at least one of its communication channels. The PHY chip is configured to calculate, after receiving a frame and before sending the data of the frame in a raw data stream, a checksum of the data contained in the frame, and to this checksum with the CRC contained in the frame. The data contained in the frame are transmitted if the comparison of the checksums delivers identical values. If the comparison delivers non-identical values, then a specifiable or specified action is executed.
