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.
Claims17
A method, comprising:
- receiving a forward error correction codeword transmitted over a communication network, the codeword comprising a parity portion and a payload portion;
- determining, based on the parity portion, to disable forward error correction for the codeword;
- disabling forward error correction for the codeword;
- determining, based on the parity portion, to bypass forward error correction for a next codeword;
- bypassing parity generation for the next codeword;
- and
- bypassing storage of the next codeword.
4 more elements
A system, comprising:
- parity analysis logic;
- forward error correction logic;
- and
- a multiplexer, wherein:
- the parity analysis logic is configured to determine, based on a parity portion of a forward error correction codeword, to disable the forward error correction logic for the codeword,
- wherein disabling the forward error correction for the codeword comprises clock gating the forward error correction logic;
- and
- the parity analysis logic is configured to control the multiplexer to output a value for a payload portion of the codeword, based on the parity portion of the codeword.
5 more elements
A method, comprising:
- receiving a status relating to transmission of a network message over a communication network;
- determining, based on the status, to bypass forward error correction for the network message;
- generating a parity value for a forward error correction codeword based on the received status, comprising:
- selecting the parity value, from among a plurality of choices, based on the received status;
- and
- transmitting the forward error codeword over the communication network.
