Aiming at the performance problem of  VPN apply , this paper proposed a new end-to-end TCP performance improving mechanism, by using the interval movement cumulated of the packets received time on receiver, which can estimate the wireless link condition. Then it marks the ELN（Explicit loss notification）bit to notify the sender and TCP could be modified so as to refrain from going into congestion avoidance. Comparing the TCP Reno and the modified TCP ,by simulations using NS2，the results show it achieves an great improvement over mobile wireless networks and can work together with current security mechanism.
