We want to implement high integrity NTP for use within our organisation.
For this reason our stratum 2 servers will poll more than one stratum 1
server which will be synchronised to GPS via an aerial. What is what is
the minimum number of stratum 1 servers we should be polling upstream in
order to ensure that the full benefit of the clock selection and
clustering algorithms within NTP is realised.
