Abstract: Systems, methods, and apparatus for rewriting or adjusting a TCP timestamp value are described. The methodology includes determining network conditions of a wireless network, and establishing a transmission control protocol (TCP) connection between a first communication device and a second communication device via the wireless network. The timestamp value within a TCP packet to be transmitted, such as as a TCP SYN ACK packet in a 3-way handshake, is adjusted with the use of a timestamp adjusting circuitry or hardware, where the adjustment is based on the determined network conditions. By adjusting the timestamp of a TCP packet prior to transmission and based on network conditions, unnecessary retransmissions are reduced. Additionally, the use of timestamp adjusting hardware allows for more efficient timestamp adjustment by offloading processor computations.
