Hi,

SNPT performance with talks about accuracy of 100msec are shown in the
following white paper:
http://www.cisco.com/en/US/tech/tk869/tk769/technologies_white_paper09186a0080117070.shtml
In out configuration we are talking about 2 machines, one using Linux
SNTP client, the other I do not know, but assume it is RT Operating
system. both machines are connected through ethernet.
It seems that if we use SNTP (as is required right now), we can't
assure more accuracy then 100msec (according to that document), which
might be probematic with our video sync requirements which are talking
about less then 40msec.
I appreciate any comments or ides,
Regards,
Ran
