APPARATUS AND METHOD FOR CALCULATING TRANSMISSION CONTROL PROTOCOL CHECKSUM

摘要

Disclosed herein is an apparatus and method for calculating a TCP checksum. An apparatus for calculating a TCP checksum includes a data division unit for dividing content to be transmitted into two or more primary data fragments by a unit of a preset byte. A first checksum calculation unit calculates first checksums for the primary data fragments, respectively. A second checksum calculation unit calculates a second checksum for secondary data to be inserted into a data area of the TCP segment using the first checksums. Accordingly, in TCP-based networks, a checksum calculation procedure is improved upon transmitting static content, so that a static content transfer rate occupying most of TCP-based network traffic can be improved.

1. An apparatus for calculating a checksum of a Transmission Control Protocol (TCP) segment, comprising:
a data division unit for dividing content to be transmitted into two or more primary data fragments by a unit of even-numbered preset byte; a first checksum calculation unit for calculating first checksums for the primary data fragments, respectively; and a second checksum calculation unit for calculating a second checksum for secondary data to be inserted into a data area of the TCP segment using the first checksums.
