Hi,

@Richard Edmands, what do you mean by "RTPengine has Cuda offloading..."? Can you share more references to that?

Thank you,
Stefan

Howdy,

So you’ve got the reserved ports range 0-1023. Then there’s a few other brackets.

In Linux there are kernel parameters to adjust these ranges, but it has been a few years.

If we’re really at the stage where we are looking at increasing the size of the range, then looking into these parameters is also worth looking into on these rtp boxes.

Typically a box wouldn’t be processing anywhere near the limits to be genuinely worth considering.

But now that RTPEngine has Cuda offloading…
