Abstract: A device implementing a forward error correction data transmission system may include at least one processor circuit. The at least one processor circuit may be configured to perform line encoding on a data stream received from a media access control (MAC) module, and periodically insert alignment markers after every number of blocks of the data stream, where the alignment markers are determined based at least in part on a data rate of an associated port. The at least one processor circuit may be further configured to transcode the data stream, where each alignment marker remains contiguous in the transcoded data stream. The at least one processor circuit may be further configured to add parity information to the transcoded data stream. The at least one processor circuit may be further configured to transmit the transcoded data stream over at least one physical lane of the associated port.

Abstract: A system includes a network interface port. The network interface port may support a network interface port mode implementing one or more physical lanes. The network interface port mode may support one or more logical lanes transported over the physical lanes. The network interface port mode may implement transfer using a specified baud rate and signaling scheme. The logical architecture of the transmission and reception stack may be selected based on the operational parameters of the network interface port mode.
