摘　　要：当前已有串口服务器数据安全通信方法无法判断网络堵塞状态,导致数据通信效率偏低,且平均响应时间较长。为解决上述问题,研究串口服务器内外网数据安全通信方法。根据串口服务器端的数据通信请求,将其IP地址及端口号输入至配置文件中。利用WCF技术,获取已输入配置文件中的信息,经串口服务器内外网判断后合成内外网数据通信路径,实现数据通信;利用缓冲系统抑制延迟和抖动对数据通信持续输出的影响。并通过包丢失率和延迟抖动两个参数判断网络堵塞状态,确保传输速率的最优化,实现串口服务器内外网数据安全通信。仿真结果表明,所提方法可最大程度缩小中间数据Shuffle所占比例,使数据安全通信效果更理想;且数据安全通信的平均响应时间显著降低且,通信性能更稳定。At present,the existing methods are unable to judge the network congestion,resulting in low data communication efficiency and long average response.Therefore,this paper presents a method of data secure communication of internal and external network of the serial port server.According to the data communication request of the serial server,we inputted the IP address and port number into configuration files.And we used WCF technology to obtain the information entered in the configuration files,all of which were judged by the internal and external network of the serial server.After that,the data communication path was synthesized to achieve the data communication.Moreover,we used the buffer system to suppress the influence of delay and jitter on the continuous output of data communication.Based on two parameters:packet loss rate and delay jitter,we judged the network congestion,and thus to ensure the optimization of the transmission rate.Finally,we achieved the safe communication of internal and external network data in the serial server.Simulation results show that the proposed method can minimize the proportion of intermediate data Shuffle and achieve a more ideal effect of data security communication.In addition,the average response time of data security communication is significantly reduced and the communication performance is more stable.
