Aim at problems existed in wireless TCP, the ARQ CAE-TCP model that it advances and jointly used by TCP and link layer picks up ARQ information from link layer to generateaffirmation to TCP data packets, decreases total ARQ times.

• 针对无线TCP 存在的问题,提出的TCP 层与链路层协调使用ARQ 的CAE-TCP模型,从链路层提取ARQ 信息来对TCP 数据包在本地产生确认,减少了总的ARQ 次数。
