I've got a question about the rationale behind the SNTP RFC2030. Basically, a valid SNTP server is supposed to be sourced directly from a reference, never from a remote NTP server. We believe this is because of the lack of sophisticated algorithms as found in NTP; e.g. sourcing an SNTP server from an NTP server is going to be inherently less accurate. Is that the gist of it, or is there other rationale as well?
Also, assuming an SNTP client is doing similar to the spec and aliasing the server time with a calculated propagation delay, and assuming a LAN rather than the internet at large, can anyone give a general feel for how far off the client is going to be from its server? Finally, are those equations for round trip time and propagation delay in RFC2030 actually correct? They aren't what I would expect, and don't even seem to match each other. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
