[c-nsp] [j-nsp] NTP Sources placement in MPLS network

[Jared Mauch]

This all depends on what you need the clocking for.

If you want just generic time for accurate logs?

Depending on what you want to do, there's cheap NTP clocks like this:

For about $350 (including S/H in the US) you get a GPS clock.  With the right location/antenna you can get signal through some roofs.

There's a variety of higher-end timing options depending on what you need.
