PAGE 6/27 TCN-TRDP3-D-BOM-024-02 TRDP-SPY Architecture and Design TRAIN REAL TIME DATA PROTOCOL 1. Introduction 1.1. Purpose As part of the IP-Train project, two new protocols namely TRDP-PD (Process Data) and TRDP-MD (Message Data) are intended to be supported by the Wireshark tool. The support is envisaged to be made available in the form of a plug-in. The existing GUI of the Wireshark V1.8.3 shall not be modified. The plug-in TRDP-SPY shall be available as a DLL for Windows platform and shared library for TRDP-spy for Linux platform. 1.2. Intended Audience The TRDP-SPY will be used primarily by TRDP Engineers. 1.3.

PAGE 8/27 TCN-TRDP3-D-BOM-024-02 TRDP-SPY Architecture and Design TRAIN REAL TIME DATA PROTOCOL 2. Overview of the Requirements 2.1.1. Description Wireshark is a popular network protocol analyser used by network professionals around the world. Wireshark is an open source and provides flexibility for plug-in development. A TRDP Analysis Tool is needed, which shall be made available as a plug-in to the popular Wireshark network protocol analyser. The TRDP-SPY plug-in shall fulfil the following requirements: • shall be available for Wireshark v1.8.3 • shall be as far as possible also support later versions of Wireshark • shall be available for both Windows XP and Linux • shall decode all TRDP PD and TRDP MD frames in the live capture window • shall support all functionalities of Live Capture window for real time analysis (capture mode) and for recorded mode (messages saved on hard disk) • shall allow declaring filters on any field of TRDP PD and TRDP MD frames • shall provide statistical functionalities • shall be able to decode and interpret the application data, using the configuration file “TRDP_config.xml” This document is subject to the terms of the Mozilla Public License, v. 2.0.
