INCREASING THROUPUT DENSITY OF TCP TRAFFIC ON A HYBRID DATA NETWORK HAVING BOTH WIRED AND WIRELESS CONNECTIONS BY MODIFYING TCP LAYER BEHAVIOUR OVER THE WIRELESS CONNECTION WHILE MAINTAINIG TCP PROTOCOL

Abstract:

A WLAN driver of the TCP proxy device transmits network packets transmitted from a sender device over the data communication network to a wireless station. TCP network packets are diverted to a TCP proxy pipeline. First, the wireless receiver device is emulated to a wireless sender device by providing an ACK packet to the sender device in order to close the TCP session on the sender side by responding to a TCP handshake with the sender device. Second, the sender device is emulated to a wireless station over the wireless network connection by initiating a TCP handshake with a wireless station including receiving an ACK packet from the wireless station and suppressing the ACK packet from an initial destination associated with the sender device.
