Join LOPSA-NJ as Jon Meek presents his latest experiments in highly
accurate, low-cost, NTP servers. These experimental servers are based
on GPS but use multiple methods to verify that they have the correct
fudge factor.

Jon will present his poster, "Validating a Stratum 1 Network Time
Protocol Server Find the Correct Fudge," recently seen at
USENIX/LISA'09, with corrections, as well as disclosing his top-secret
grandiose future plans, including:

     + using his new hot air re-work station to replace crystal oscillators
        from motherboards in the servers

     + replacing the crystal with a fancy frequency synthesizer that has
        an oven-controlled oscillator

     + using a GPS that outputs a 10 MHz clock signal as the base for
        the clock

As Jon recently said on the LOPSA-NJ mailing list, "Stable system
clock -> Better NTP stability."

It's clear that Jon has been a busy in his laboratory. We're all
excited to see what he's cooked up!


Jon is a Senior Technical Lead at Pfizer with primary responsibilities
in security, logging, Internet and third party connectivity, and
network performance testing and monitoring. He joined American
Cyanamid, a Pfizer predecessor company, 27 years ago as an
experimental physicist to work on a project that required very
accurate frequency measurements.
