re-send information. Backward Error Correction is used in situations where some of the transmitted data has been lost or corrupted during transit and the transmitting device must resend the information in order for the receiving forward and backward error correction device to understand the transmission. Backward Error Correction is the opposite of “Forward Error Correction”,

in which a transmitting device simply sends redundant information to make up for any potential errors. How Backward Error Correction error correction techniques in computer networks Works Backward Error Correction is dependent on a number of protocols and algorithms, such as parity bits, cyclic redundancy checks, and longitudinal redundancy checks, but relies on the same procedure. As usual, a transmitting device will

send data to a receiving device. The receiving device will then run checks to ensure that all of the information is present, readable, and makes sense. If the received information does not make sense, is not all there, or cannot be read for any reason, the receiving device will send a request to the transmitting device to resend that data. Applications Backward Error Correction is often used instead of Forward hamming distance error correction Error Correction because it requires less bandwidth. However, because Backward Error Correction requires the receiving device to receive a signal before it requests redundant information, it requires more time than Forward Error Correction and may even use more bandwidth for individual transfers due to constant messaging between the two devices. While Forward Error Correction is usually preferred on systems that are prone to errors, such as long-distance communications systems, Backward Error Correction is ideal for systems that rarely have errors or only handle small amounts of data.

Backward correction requires a return channel, by contrast with forward http://www.encyclopedia.com/doc/1O11-backwarderrorcorrection.html error correction.There are two ways in which the return channel can be used to indicate errors: positive acknowledgment and negative acknowledgment. With positive acknowledgment, the receiver returns confirmation of each block received correctly, and the transmitter is prepared to retransmit a block that is not acknowledged within an appropriate time. With negative acknowledgment, the receiver returns a request to retransmit any block received erroneously, and the transmitter is prepared to retransmit such a block (implying that the transmitter retains a copy of every block sent, indefinitely).Since the return channel itself may be prone to errors, and to limit the amount of storage necessary at the transmitter, the positive acknowledgment and retransmission (PAR) technique is generally preferred.

Because FEC does not require handshaking between the source and the destination, it can be used for broadcasting of data to many destinations simultaneously from a single source.
