Abstract
An improved method and apparatus are provided for producing transmission control protocol (TCP) checksums using internet protocol (IP) fragmentation. A transmission control protocol module receives packet data to be transmitted and prepares a first internet protocol data fragment without a checksum for the received packet data. The first internet protocol data fragment is transmitted. Collecting checksum is performed during the transmission of the first internet protocol data fragment. Then an internet protocol header fragment including the collected checksum is transmitted.
