PROBLEM TO BE SOLVED: To prevent a channel utilization rate limited by flow control by the transmission control protocol TCP from being deteriorated in a network having a high transmission rate. SOLUTION: Inter-network systems (routers) 307, 308 monitor TCP connection between adjacent hosts 301, 302, 303, 304, 305 and a host being a communication partner party of any of the adjacent hosts 301, 302, 303, 304, 305 and overcome a delay produced with the pastier host by sending a reception acknowledgment segment to any of the adjacent hosts on behalf of the partner host when detecting deterioration in the channel utilization rate due to the TCP flow control. Furthermore, the routers 307, 308 store data sent from the adjacent hosts in their memories and conduct re-transmission acknowledgment with respect to a re-transmission request from the opposite host by using the data stored in the memories. |
