Title : Hybrid Unicast/Multicast DNS-Based Service Discovery
Author : Stuart Cheshire
Filename : draft-ietf-dnssd-hybrid-00.txt
Pages : 19

Abstract:
Performing DNS-Based Service Discovery using purely link-local
Multicast DNS enables discovery of services that are on the local
link, but not (without some kind of proxy or similar special support)
of services that are outside the local link. Using a very large
local link with thousands of hosts improves service discovery, but at
the cost of large amounts of multicast traffic.
Performing DNS-Based Service Discovery using purely Unicast DNS is
more efficient, but requires configuration of DNS Update keys on the
devices offering the services, which can be onerous for simple
devices like printers and network cameras.
Hence a compromise is needed, that provides easy service discovery
without requiring either large amounts of multicast traffic or
onerous configuration.
