Hi everybody!! My question is about Time Accuracy of NTP/SNTP protocol. I want to know if is possible to have precision of 1ms(could be < 1 ms?) using SNTP in a network with 50 hosts(is the same with 100 hosts?) using only swithes, no routing. All these hosts are syncronized with a Meinberg GPS. The traffic is low(~25%). Is it possible to have the same time accuracy of IRIG-B for example?
The internal clock in my devices(hosts) starts with the crystal frequence. A typical offset or frequence tolerance of the crystal is less then 1ms/minute. The resolution is about 0.9ms and the devices acts as unicast clients, asking GPS every minute. Is it enough? The Time Accurancy could be better if I could ask GPS twice a minute? A broadcast implementation with GPS sending time every minute could help? I know that these kind of issue have many variables but the main question is: Is possible to have precision of 1ms(could be <1ms) with SNTP? Thank you very much _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
