TCP/IP COMMUNICATION REPEATER SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a communication system using a TCP/IP capable of preventing deterioration of through-put due to data transfer delay without changing the standard specifications of the TCP/IP. SOLUTION: A transmitted No detecting part 112 of an outgoing relay part 11 detects the sequence number of transmission data to be transmitted from a data transmission side B. An ACK changing part 123 of an incoming relay part 12 changes the contents of the ACK analyzed by an ACK analyzing part 122 in order to relay transmission data for data quantity requested by a data reception side A based on the contents of the ACK and the sequence number of the latest transmission data detected by the transmitted No detecting part 112.
