Abstract:
An apparatus for high speed communication on an asymmetric line, wherein said apparatus is set at a position on a communication line between first and second computers which respectively communicates by a communication protocol having a flow control and a transmission delay between said position and said first computer which is less than a transmission delay between said position and said second computer, further wherein said apparatus sends and receives a packet to/from said first and second computers, said apparatus comprising;means for generating, instead of said second computer, an ACK packet in response to a data packet sent from said first computer, means for managing information regarding a connection between said first and second computers and a SYN packet and a SYN+ACK packet by obtaining and recording said information, means for storing a FIN packet, buffer means for storing said data packet sent from said first computer, means for transferring to said second computer a data packet which is sent from said first computer and of which the data amount is larger than an amount which notified by said second computer as a maximum amount of TCP window size by which said second computer can receive, for transferring to said first computer a data packet sent from said second computer, and for not transferring to said first computer an ACK packet sent from said second computer, wherein a high speed communication from said first computer to said secon computer is performed.
