High-bandwidth Ethernet uses forward error correction, but I'm not aware of any higher-than-physical internet protocols that do, unless you count erasure codes

High-bandwidth Ethernet uses forward error correction, but I'm not aware of any higher-than-physical internet protocols that do, unless you count erasure codes a la QUIC
- waterhouse 8y agoIP, TCP, and UDP all have checksums, though (a) that's less powerful than error correction and (b) the above are weaker than the Ethernet checksum (Ethernet is 32 bits while the others are 16 bits, and also I think these three are all addition- or XOR-based instead of a polynomial CRC).
