A technique used by a receiver for correcting errors incurred in transmission over a communications channel without requiring retransmission of any information by the transmitter; typically involves a convolution of the transmitted bits and the appending of extra bits by both the receiver and transmitter using a common algorithm.
A technique for correcting errors incurred in transmission over a communications channel. With FEC, errors are corrected at the receiving end of the channel, thereby reducing the amount of data that must be retransmitted due to errors.
Foward Error Correction. A class of methods for controling errors in a communication system. FEC sends extra information along with the data, which can be used by the receiver to check and correct the data. Examples of Foward Error Correction algorithms are Reed Solomon, Viterbi and Turbo Product Coding
Forward Error Corrections. A system of error control for data transmission wherein the receiving device has the capability to detect and correct any character or code block that contains fewer than a predetermined number of symbols in error.
A means of correcting occasional errors and validating data in a broadcast communication system.
A technique that ensures the transmitted message is received at the receiving end without error.
FEC is a method that increases the reliability of data communication by resending a message if there was an error in the original transmission.
forward equivalence class
forwarding equivalence class. A collection of destinations that are mapped to an MPLS LSP.
technique used to overcome some type of errors created by transmission on noisy channels, by adding redundancy bits to the main data transmission.
Forward Error Correcting. A communication technique used to compensate for a noisy transmission channel. Extra information is sent along with the primary data payload to correct for errors that occur in transmission.
Forwarding equivalence class. Criteria used to forward a set of packets in an equivalent fashion. Forwarding equivalence classes are defined in the base LDP specification and may be extended through the use of additional parameters. FECs are also represented in other label distribution protocols.
