AMWA INFO-004 NMOS Implementation Guide for DNS-SD
What does it do?
- Explains the use of DNS-SD in NMOS environments.
- Provides a practical “how-to” example of how to set up a BIND9 DNS server for NMOS use.
- Gives example configurations for other DNS servers.
Why does it matter?
- DNS Service Discovery (DNS-SD) provides a simple and flexible method to discover NMOS Registration and Discovery Server (RDS) Services.
- The NMOS RDS provides information about NMOS nodes, devices, and APIs. There must be a common way to locate the RDS in order for an NMOS component to register itself for discovery by other NMOS components.
How does it work?
The example add records to a BIND9 DNS server such that the server responds to standardized queries with information that indicates:
- The fact that the DNS server provides Service Discovery
- Where the NMOS RDS may be found on the network
The NMOS Testing Tool creates a simple web service for testing implementations of all NMOS APIs.
