在接受报文的时候，报文经常有丢包现象，一个报文发生丢包会污染下一个报文，会导致连续两组报文无效的现象。针对上述问题，本文提出一种在读取报文内容的同时也要检测报文内容的算法。通过实验证明该算法能有效防止因丢包而污染下一个报文。 When receiving message, the message often has the phenomenon of packet loss, and the packet loss of message will pollute the next message, which will lead to two invalid consecutive messages. In view of the above problems, in this paper, a new algorithm is proposed to detect the message content while reading the message content. Experiments show that the algorithm can effectively prevent the pollution of the next message due to the packet loss.
