摘要:

在数据链路层停止等待协议中,当数据帧出现差错时,解决的办法是等待超时重发。本文利用量子隐形传态的纠缠关联及瞬时传输特性对该算法进行了改进,一旦数据帧传输出错,接受方立即发送否认帧以减少发送方的等待时间,从而缩短两个成功发送的数据帧之间的最小时间间隔。分析表明,本方案提升了传输效率,改进了经典的停止等待算法的性能。

Abstract:

When a data frame is lost or received corrupted during transmission, the solution adopted by the stop and wait protocol of the data-link layer is overtime retransmission. In this paper, we propose an improved algorithm by utilizing the correlation in quantum entanglement and instantaneous transmission of quantum teleportation. When something wrong happened during the data transmission, our algorithm sends negative frame and the acknowledgement frame instantaneously, which reduces the minimum time interval between two successful data frame transmission. Compared with the classical stop and wait algorithm, quantitative analysis illustrates that our algorithm improves the data frame transmission efficiency.
