Attila,
Do get the Dave Mills book.
You can strip away a number of methods under certain assumptions to make
the system simpler to understand, and then add them back in.
The NTP packet exchange get's you a two-way hand-shake with time-stamps,
which provides you with a offset (time error against the remote node).
This is first processed for a FLL style lock-in which then swaps over to
a PLL mode. Then it is a pretty simple PLL, with the capability of reset
the time offset which is rarely used.
Things like the cluster algorithm weighs many sources etc.
Cheers,
Magnus

Moin,
I am a little bit stuck here. I am trying to work out the math behind
a synchronization of clocks problem. It shouldn't be too difficult,
but every couple of minutes I'm getting stuck at some details and it
takes me always a lot of time to get around it. I'm pretty sure that
what I am doing is similar to what NTP does locally after it got an
estimate on it's time difference. I tried to look up what NTP does
but I got lost in the huge amount of papers/presentations.
Could someone point me to some papers that explain what NTP
does locally? If possible in compact form.
Thanks in advance
Attila Kinali
