Hi, I am running several (less than 30) servers on LAN with these restrictions : - no Internet - Windows XP/2003 - no GPS possible - I need less than a millisecond accuracy.
5 of them are on the same switch and two in an other building. Latency between buildings is less than 20ms. There _might_ be an internal NTP server synchronised to a server on internet but let say i dont have to count on it. If : - i choose one "good" server as my time reference (local clock) and synchronised all the other clients to it - i put all servers in peer mode - i put a pci card that uses a TCXO to replace the hardware clock (any known vendors ? i dont care about GPS sync) - limit maxpoll (what is the impact ?) - change OS (again what is the impact ?) is the accuracy of a millisecond "achievable" in those conditions ? If not, what can i do to achieve it ? _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
