No, NTP is a different protocol altogether. NTP runs on top of IP. IEEE-1588 runs on the side IP and needs at least support in the driver layer - if not the hardware layer! NTP is supposed to be used over the wide area network. IEEE-1588 is for local area networks - mostly ethernet. NTP relies on IP for routing to other networks, IEEE-1588 relies on "boundary" clocks between the networks, i.e. the routers have IEEE-1588 implemented. Take a look at http://ieee1588.nist.gov/ (Ethereal is mentioned as understanding IEEE-1588 :-) Esben On Mon, 23 Aug 2004, Gene Heskett wrote: > On Monday 23 August 2004 03:51, Esben Nielsen wrote: > >Does anyone know about that standard for time syncronization?
