That avoids lots and lots of jitter. It avoids some jitter. Does that mean that you have to have special hardware (special network cards, or special network card drivers?) It does nothing for the 300us jitter I see on my ADSL connected computer. It might do something for the 10us jitter I see on my ethernet connected lan-- probably take it down to 8us or something (has anyone tested where the jitter is-- in the network cards or in the switches?) >-- >These are my opinions, not necessarily my employer's.
