Universal service discovery framework?
by ac on Thursday 28/Apr/2005, @16:22

Would it be possible to implement some kind of 'universal service discovery framework' which needs to be implemented in apps only once, starting with Zeroconf, but can then be transparently extended with other such protocols like SLP, uPNP and whatever other service discovery protocols proprietary application developers come up (like what Skype uses)?

This is exactly my plan for future. However, I still don't know how to deal with differences in service types between SLP and DNS-SD. SLP uses abstract-type:protocol (where abstract-type is application specific, for example 'drivers' and protocol is high-level protocol like http, ftp, etc.).
DNS-SD uses [_subtype]._type._protocol where protocol can be UDP or TCP, type is application-specific protocol like rfb, http, ftp, etc. Subtype adds extra info (for example _anon._ftp._tcp). So what I need is kind of abstract naming that can be translated into DNS-SD and SLP (and possibly others) forms.

That's cool. Hope you come up with a good solution for this problem.
