If you don't need microseconds, you don't need a magic switch, 1588 gets you well below 1msec on regular switches, provided you don't overload that network segment. Regular NTP can also get there, if you tweak the poll-rate down, but 1588 is a more robust protocol. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
