COMMUNICATION DEVICE, IMAGE FORMATION DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To make it possible to select whether or not a confirmation response to a packet received from another device is made to be a delay confirmation response, for each connection established between its own device and the other device.

SOLUTION: An ACK information management part 5 in a socket level 2 of a reception host stores ACK information for designating which of a delay ACK and an immediate ACK is to be a confirmation response to a received packet from a transmission host in relation to a socket number and TCP connection information. The reception host determines which of the delay ACK and the immediate ACK is to be selected for the packet received in the TCP connection by allowing an ACK processing selection part 6 in a TCP level 3 to refer to the related information.
