AMWA INFO-004 NMOS Implementation Guide for DNS-SD
About INFO-004
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
INFO-004 has been developed by the Advanced Media Workflow Association as part of the Networked Media Open Specifications initiative. See here for an overview of NMOS specifications.
The NMOS Testing Tool creates a simple web service for testing implementations of all NMOS APIs.
