Distributed File System | prof. Giovanni Chiola | ![]() |
Forward error correction codes traditionally adopted in communications without retransmission. | ||
Based on Galois' field arithmetics. | ||
Allow detection and/or correction up to a maximum predefined number of erroneous bits per word. | ||
Correction is computationally expensive, but "bit erasure" can be treated in a simpler way. | ||
Very flexible correction schema, easily adapted to RAID operation. | ||
