SLIDE 2

 One of the best open source packet analyzers available today  Captures network packets and tries to display content as detailed as possible

Wireshark – network analyzing tool

 Easy and user friendly way to troubleshoot network problems

Multiple tools to extract the desired packets, i.e. network interfaces

and display filters for protocol, IP, port, etc.  Create packet dissector for accelerator equipment

Quick tool to analyse the data

What? When/Why?

 How to build (more in Wiki)

Create a plugin either in
an existing Wireshark build

(bdisoft/development)

r your own

Build and run your dissector - example LHC FBs
