Abstract
A TCP gateway terminates TCP flow control and retransmission control of TCP packets which are input from a transmitter side terminal, in place of a receiver side terminal. Also, the TCP gateway transfers the packet to the TCP gateway which is located on the opposite side, by using selective retransmission procedures in a data link layer using SSCOP and by using peculiar flow control procedures. In addition, the TCP gateway provides the process of transferring the packet to the receiver side terminal in accordance with the TCP process procedures in place of the transmitter side terminal, to a plurality of TCP connections simultaneously.
