Realtimeness of socket in Labview Realtime

[auralius]

Hi All,

I know that Labview Realtime has already provided way to do deterministic commucicatoion, such as via FIFO. What I would like to know is about the realtimeness of the socket (UDP and TCP) in Labview Realtime. As in Xenomai and RTAI, they have RTNet (http://www.rtnet.org/) which allows TCP and UDP realtime communication.

How does actually the socket in Labview Realtime behave? Is it more like normal socket as in Windows and Linux?

Thanks.

Hi,

LabView RealTime uses dstp.

More information about this protocol can be found here:

Thanks for your reply.

I think dstp lies above tcp and it is not a realtime protocol.

I would assume the socket in LabVIEW behaves as normal socket as in Windows or Linux and it is not realtime.
