"When TCP runs over IPv4, the method used to compute the checksum is defined as follows: The checksum field is the 16-bit ones' complement of the ones' complement sum of all 16-bit words in the header and text. The checksum computation needs to ensure the 16-bit alignment of the data being summed. If a segment contains an odd number of header and text octets, alignment can be achieved by padding the last octet with zeros on its right to form a 16-bit word … When TCP runs over IPv4, the method used to compute the checksum is defined as follows: The checksum field is the 16-bit ones' complement of the ones' complement sum of all 16-bit words in the header and text.
