AMWA INFO-004: NMOS Implementation Guide for DNS-SD

This repository holds the source for this Implementation Guide, part of the family of Networked Media Open Specifications from the Advanced Media Workflow Association

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
