Carrier Class NTP
So, what with IEEE 1588 (PTP, Precision Time Protocol or whatever you want to call it!) about to be officially released from the confines of the IEEE ballot process sometime later this year, NTP seems to making a bit of a comeback...
Take the concept of hardware assistance from 1588, change the update rates and filter/servo algorithms from "Standard" NTP (whatever that is!) and what do you get? This thing termed "Carrier Class" NTP - ccNTP - also including a magical sprinkle of traditional Telecom Sync ideas (PRC traceability, redundancy etc.)
In terms of a proper standard - who knows? NTP V3 is the latest RFC release, V4 working party still deliberating over things. TICTOC have somewhat confused the issue (for ccNTP at least) by setting their scope as all things timing over network related...
Time to wait and see?
