Show that the Internet checksum can be computed by first taking the 32-bit ones’ complement sum of the buffer in 32-bit units, then taking the 16-bit ones’ complement sum of the upper and lower halfwords, and finishing as before by complementing the result. (To take a 32-bit ones’ complement sum on 32-bit twos’ complement hardware, you need access to the “overflow” bit.)
