摘要
在一个典型的以太网环境中,一个设备使用UDP协议向另一个设备发送数据时,可能会出现网络丢包的情况。当数据量较大或网络结构比较复杂时,丢包问题定位比较困难。本文通过对数据传输中不同节点的时间信息、时序信息进行研究,提出将相邻数据包的时间戳、包序号等时序信息进行比对,以图形方式展示差额结果,通过图形的特征快速定位丢包数据出现的故障点,该方法能够有效节约定位分析时间,提高分析效率。
In a typical Ethernet environment,when one device uses UDP protocol to send data to another device,network packet loss may occur.When the amount of data is large or the network structure is complex,it is difficult to locate the packet loss problem.This paper studies the time information and time sequence information of different nodes in data transmission,and proposes to compare the time stamp,packet serial number and other time sequence information of adjacent packets,to display the difference results in a graphical way,and to quickly locate the fault point of packet loss data through the characteristics of the graph.This method can effec⁃tively save the location analysis time and improve the analysis efficiency.
