The Service Registration Protocol (SRP) for DNS-based Service
Discovery (DNS-SD) uses the standard DNS Update mechanism to enable
DNS-SD using only unicast packets. This makes it possible to deploy
DNS-SD without multicast, which greatly improves scalability and
improves performance on networks where multicast service is not an
optimal choice, particularly IEEE 802.11 (Wi-Fi) and IEEE 802.15.4
networks. DNS-SD Service registration uses public keys and SIG(0) to
allow services to defend their registrations.
This document is a product of the Extensions for Scalable DNS Service Discovery
Working Group of the IETF.
This is now a Proposed Standard.
