ABSTRACT:
A network includes a TCP-in-TCP tunnel between a mobile device, which includes a TCP client and a gateway, and a TCP server, which resides in a subnet. Another gateway in the subnet receives and caches TCP packets and acknowledgments (ACKs) from the TCP-in-TCP tunnel. In response to receiving an indication from the TCP server that it has not received a cached TCP packet, the second gateway may resend the packet without relaying the indication to the TCP client, and the first gateway may send a control message instead of a complete TCP packet to the second gateway.
