ABSTRACT:
A protocol translation device realizes the merit of communications via the T/TCP protocol even if only one of devices in communication is compatible with T/TCP. The protocol translation device conducts protocol translation to relay communication packets sent and received between a TCP channel and a T/TCP channel, including a means for translating a T/TCP packet into a TCP packet by deleting a CC option and a CCnew option from the T/TCP packet, a means for translating a TCP packet into a T/TCP packet by adding CC, CCnew and/or CCecho options to the TCP packet and setting a CC value, and a means for assigning a value that is 16 bytes less than the maximum size of the packet to an MSS option for a communication device that communicates by the TCP protocol and instructing the communication device to transmit data with a packet that is 16 bytes or more smaller than the maximum size of the packet.
