Are you wanting to post-process a log file created by WireShark, or are you wanting to perform live processing of data recorded by WireShark?  Your request/question is unclear...what specific questions do you have about doing this?

my project is about Voice over ip

so iam going to sniff the network to extract RTCP and put the results in labview ,i guess there is a way to do that from labview since tshark can be run from the command line  so system excuter in labview will do ... the thing i don't know is i got ip headers sniffed how can i put that into strings and and decode them using laview in order to plot them in a graph ??

You can either setup wireshark to log that traffic and post process the log file or you will have to interface to the WinPCap driver that Wireshark is using to sniff the network traffic. There has been some work done to interface to WinPCap here in the past but the project has to my knowledge never gone to a fully fledged state, so I would expect you to have to do some work on that level too.

Hi,

If you're getting the IP headers through as strings or IP addresses LabVIEW offers 2 functions to convert String to IP, IP to String under Data Communication > Protocols > TCP in the block diagram.

thanks

Hi,

check the software tab at ControlSAG company, www.controlsag.ro. A libray for network sniffing and network parameters checks is provided.
