Abstract: This paper puts forward a GACK-based improved algorithm of slide window protocol, which asks that receiver sends an acknowledgement for a group of packets according to sender’s request. Compared to delayed ACK, the algorithm reduces the number of ACK, and eliminates bad influence on efficiency of the data transportion. The simulation results demonstrate that the algorithm reduces the request to network sources in slide window protocol and keeps nice transporting efficiency.

摘要：

提出了一种基于成组确认的滑动窗口协议改进算法，该算法规定接收方根据发送方要求对一组数据报文进行统一确认。同延迟确认相比，大大减少了ACK数量，并消除了延迟ACK对传输效率的影响。仿真试验结果表明，该算法减少了滑动窗口协议对网络系统的开销要求，并保持了良好的TCP传输效率。
