A Library Implementation for DDS Packet Capture and Parsing based on Wireshark

This paper presents an library implementation called NPGA (Network Packet Grabbing and Analysis), which serves as a comprehensive solution for packet capture and parsing in the Data Distribution Service (DDS) environment, with a particular focus on the Real-Time Publish-Subscribe (RTPS) protocol. The NPGA library is engineered with a modular architecture, integrating a customized version of the open-source Wireshark dynamic library for in-depth parsing. It offers a flexible API through a callback mechanism, enabling developers to conveniently capture and analyze DDS traffic. This library will furnish a toolkit to facilitate in-depth analysis and monitoring, thereby making it more accessible for developers to utilize and integrate into their projects.
