WebIf the calculated checksum is 0, it is stored as all one bits (65535), which is equivalent in ones-complement arithmetic. If the transmitted checksum is 0, it indicates that the sender did not compute the checksum. If the sender did compute a checksum and the receiver detects a checksum error, the UDP datagram is silently discarded. WebJul 10, 2012 · The basic idea is tcp->check += (new_val - old_val). It's a bit more complicated than this, becuase: 1. old_val and new_val need to be 16-bit values, which are aligned on 2 bytes (e.g. changing a port number). 2. The checksum uses ones complement arithmetic, so you need to do "carry feedback". cheap click and lock vinyl flooring
