Technical Summary
Despite its name, DNS-Based Service Discovery can use naming systems
other than the Domain Name System when looking for services.
Moreover, when it uses the DNS, DNS-Based Service Discovery uses the
full capability of DNS, rather than using a subset of available
octets. In order for DNS-SD to be used effectively in environments
where multiple different name systems and conventions for their
operation are in use, it is important to attend to differences in the
underlying technology and operational environment. This memo
presents an outline of the requirements for selection of labels for
conventional DNS and other resolution systems when they are expected
to interoperate in this manner.
Working Group Summary
Early in the life of the draft there was extensive discussion (with
a very few people supplying most of the bits) on clarifying the
scope of the draft and sometimes-diverging terminology, since DNS
operators and implementers think of interoperability issues between
name resolution protocols differently than operators and
implementers of mDNS or other such protocols. Those confusions
appear to have been resolved in the final draft.
The primary difference between the individual -00 version and the
current one is extensive explanatory text on the nature of the
problem being addressed and some of those divergent uses of
terminology.
Document Quality
This document is intended as advice to implementers, to promote
interoperability among multiple protocols. Review in DNSOP was
requested, as it discusses operational conventions about the public
DNS.
