摘要在测控网中,PDXP 协议作为一种私有协议用于传输测控关键信息。尤其是在航天测控任务中,测量船与陆地控制中心
传输的实时测控数据均为 PDXP 协议数据,因此对 PDXP 协议数据监视尤为重要。针对测量船测控信息传输链路曾出现过丢包、乱
序的现象,通过 Wireshark 抓包软件内置的 Lua 开发引擎,研究开发对 PDXP 数据包进行解析分析的插件。经任务检验,插件能够有
效地对 PDXP 数据包中各字段进行解释,并且对丢包和乱序进行提示,从而帮助网管人员监视网络链路状态。

Abstract As a proprietary protocol PDXP is used for transferring key information of monitoring and control data in TT&work.

Particularly in aerospace monitoring tasks the real-time monitoring and control data transmission between tracking ship and land-based control

centre are all the PDXP protocol data so it is especially important to monitor PDXP protocol data. For the phenomena of packet loss and out-

analysis plug-in for PDXP data packet through the built-in Lua development engine of Wireshark packet analyser software. To be examined in
