The method organizes traffic of General Packet Radio Service Tunneling Protocol Transmission Control Protocol (GTP TCP) data packets over a network with a satellite link connecting a hub side and remote terminals, involving a TCP spoofer at either side. It includes the following steps: a TCP spoofer receives a GTP TCP data packet, either for transmission or already transmitted over the network. The system checks for an existing GTP spoof session; if none exists, a new session is created, saving the packet sequence number as a reference. If an existing session is found and its stored reference equals a predetermined value, the reference number is updated with the sequence number of the received packet, depending on whether the packet is being sent or has already been sent.
