SYSTEM AND METHOD FOR CALCULATING CHECKSUMS OF TCP SEGMENTS/UDP DATAGRAMS IN IPV4/IPV6 PROTOCOL TRANSLATION

摘要

Disclosed is an improved system and method for calculating a checksum of a TCP segment/a UDP datagram when translating IPv4 into IPv6, and vice versa. The present invention has advantages in that a desired checksum value can be obtained even without including a value of a data region that is newly assigned upon calculation of a checksum, thereby significantly reducing the time taken to calculate the checksum value with the least amount of calculation and enhancing the performance of a packet translation processing.
