Dear all,
Thank you very much for support,
i do not have 1000,000 client, i need those ntp servers to serve a load
between 100000 to 1000000 clients
over a public network with an accuracy of 100ms
those clients will use dns round robin to resolve 4 external ip, 2 IPs on each
site.
DO NOT USE ROUND ROBIN DNS for NTP!
i have 4 servers with 4 ntp server slot card each ( meinberg M900)
1 ntp server card can support 10,000 request.
how can implement that with load balancing between site?
do 8 ntp servers per site enough to support request for min 100000 to 1million
clients
and be load balanced between site with round robin?
on each site, do all servers need to be on the same subnet?
do i need more than 4 external ip addresses to nat all of ntp server on each
site?
DO NOT USE NAT!
Please reread my previous message, NTP is designed to handle all the
load balancing and fault tolerance you could wish for.
Terje
again thanks for all

Dear all,
i m currently working on some project that needs a particular ntp distribution
design:
i have to site with 4 public ip address, that can be used on both site, i need
to serve between 100000 client to 1 million.. load balanced either on 1 site or
both.
i have on each site 2 box with 4 ntp server (slot card) that can deliver
synchronize 10,000client per card
i can also use a L4 load balancer on each site if required, also dns round robin
i would like to know how can i design a proper ntp network with redundancy on
both site that can handle such client request.
Please expert kindly advise
Thank you

Please use your return key! Your message overflows a 22" wide screen!!!
You will need a very fast link to your internet provider. I think T1
service might be sufficient. Consult an expert or two!
Be certain that your contract with your Internet Provider (IP) allows
you to operate a server. Some providers do not. Any IP should be able
to handle the load but will almost certainly expect you to pay for the
bandwidth your server will require.
