Hello Greg, Thanks for your reply. My current question is related to
real-time scheduling capabilities of Solaris 8 and/or Solaris 9. The
problem can be boiled down to the following very simple tests:

1. Can I use nanosleep to try to wake up every 10 ms (on average)?
2. Can I use SIGALRM instead?
3. Can I use gethrtime instead?

For the time being, you can completely ignore the network, transfering
data, IP, TCP, UDP and/or jitter buffers...

Wow... that's why I hate posting on Usenet... because people jump into
conclusions... I'm sorry Greg... I appreciate your taking the time to
share your knowledge, but you know _NOTHING_ about the design of my
"real-world" application... all you know is the PROBLEM STATEMENT as
stated in my opening post: "--How to obtain reliable 10 ms timing from
Solaris on a 450 MHz UltraSparc2?"... Even though my post was very well
articulated, you start making assumptions about delays in intervening
switches and routers and claiming that "it sounds like I have not
designed my system properly"... That's quite a disappointing response
from someone like yourself who could probably offer something positive
to the community...
