Well, they *are* separate protocols, but are mostly in practice used together; mDNS plus DNS-SD plus IPv4LL *is* ZeroConf, more or less. And IPv4LL is not needed if the machines already have an IP address configured; this makes IPv4LL something only used on startup; normal programs assume that an IP address is configured already and just use mDNS and/or DNS-SD directly. > My impression is that those three protocols are normally found > together and so it could be useful to consider them as part of the > same "protocol suite".

Well, some programs do seem to use mDNS or DNS-SD without implying the use of the rest of ZeroConf; see for example libnss-mdns. > I'm not a zeroconf expert though, so I'll accept your judgement. If you want to be conservative about adding tags, you might add only protocol::zeroconf to begin with and revisit the issue about mDNS and DNS-SD at some later date, to see if more programs use the protocols separately. I guess one should, in that case, tag for instance libnss-mdns with protocol::zeroconf, even though it does not concern itself with all of the ZeroConf protocols. /Teddy Hogeborn, not a ZeroConf expert either - -- The Mandos Project http://www.fukt.bsnet.se/mandos -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFJebl+OWBmT5XqI90RAowmAJ9hwkH9LEUU53FBPRbmCGoxUamJMwCgijhk qXUL4fCzFhCH79TuvOA744Y= =3hmo -----END PGP SIGNATURE----- _______________________________________________ Debtags-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/debtags-devel
