Abstract: Devices, systems, methods, and processes for transmitting and receiving one or more data packets are described herein. A device may face an internal non-deterministic delay in processing causing a gap or an interruption during transmission of the data packet. During the gap, the device can transmit one or more Intra-Packet Idle (IPI) words between the transmission of the data packet. The IPI words can be ignored or discarded by a receiver. The device may transmit the data packet into multiple parts by transmitting the IPI words between the parts. The receiver can receive the parts of the data packet and the IPI words and retrieve the data packet based on the parts of the data packet. The device may set a configurable threshold value indicative of a maximum number of the IPI words that can be transmitted during the gap of the interruption, such that the receiver can efficiently identify and discard a runt packet. The device does not require a buffer to fetch and store the data packet prior to the transmission, thereby eliminating a latency caused by the buffer.

Abstract: Techniques for forward error correction are disclosed. These techniques include receiving a forward error correction codeword transmitted over a communication network, the codeword including a parity portion and a payload portion. The techniques further include determining, based on the parity portion, to disable forward error correction for the codeword. The techniques further include disabling forward error correction for the codeword.
