We have a server (ntp.cs.uu.nl) which is included in the .tr zone and rated at gigabit speed. It's placed in the network in such a way that no stateful firewall is in the way.
My systems are also connected directly to the internet, so there is no stateful firewall in the path, which could cause problems.
Normal traffic is around 1000 requests/second. The peak at the leap second announcement was 24488 requests/second. About the same numbers as seen by Anssi Johansson.
Yes, I remember the massive peaks for the tr zone before the leap second.
As the requests are UDP, I assume, that requests/second corresponds to packets/second, which I am metering with MRTG. My servers have currently around 150 packets/minute, which calculates to around 2.5 packets/second. So if the bandwidth rating is linear, then for my 10 Mbit/s I will probably get an additional 10 packets/second, when included in the tr zone. So this is in the end around 12.5 packets/second and only 5 times more then now (I just ignored IPv6 in the calculation, as this probably wont matter at this time). I guess this should then be doable, even when I let add all my 6 (3x IPv4 + IPv6) servers to the tr zone.
I will consider this and then send the details to Ask in a private e-mail.
Thank you Koos for sharing your numbers, this was very helpful. bye Fabian _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
