Abstract Abstract
The Service Registration Protocol for DNS-Based Service Discovery The Service Registration Protocol for DNS-Based Service Discovery
uses the standard DNS Update mechanism to enable DNS-Based Service uses the standard DNS Update mechanism to enable DNS-Based Service
Discovery using only unicast packets. This makes it possible to Discovery using only unicast packets. This makes it possible to
deploy DNS Service Discovery without multicast, which greatly deploy DNS Service Discovery without multicast, which greatly
improves scalability and improves performance on networks where improves scalability and improves performance on networks where
multicast service is not an optimal choice, particularly 802.11 multicast service is not an optimal choice, particularly 802.11
(Wi-Fi) and 802.15.4 (IoT) networks. DNS-SD Service registration (Wi-Fi) and 802.15.4 (IoT) networks. DNS-SD Service registration
