Crc in ethernet frame

WebDec 27, 2024 · CRC has advantages over other error detection methods in terms of speed, cost, and correctness. Therefore, CRC has become the most commonly used error detection method in the computer information and communications fields. For example, a standard Ethernet frame ends with a 4-byte frame check sequence (FCS) for error detection. … WebOct 3, 2024 · If the frame needs to be routed, the current (incorrect) FCS field's value would be computed after the frame's Ethernet header is rewritten. This action is known as "stomping" the CRC. Forward the remainder of the Ethernet frame (along with the stomped CRC) out of the egress interface according to the forwarding decision made on the frame.
