- Abstract
- The use of IP networks for professional AV media is becoming prevalent within the broadcast industry with standards such as SMPTE ST 2110 now available for streaming uncompressed video, audio, and ancillary data. To allow full interoperability between different manufacturers’ equipment, common methods for discovery, registration, and connection management of media devices are essential. The Advanced Media Workflow Association (AMWA) has been developing the Networked Media Open Specifications (NMOS) for this purpose, leading to the publication of interface specifications, including IS-04 for discovery/registration of NMOS Nodes and IS-05 for management of connections between Nodes. These use RESTful application programming interfaces (APIs) to communicate between applications and devices and are gaining widespread adoption. A key requirement within the industry is that these APIs scale successfully in the very large installations typical of real-world deployments. To help address this, Sony has been leading an AMWA NMOS Scalability study to test these protocols for installations comprising thousands of media devices. This paper describes our test methodology using a simulated network environment, provides several experimental results, discusses their implications, identifies best practices for deployment, and suggests whether further API enhancements may be beneficial.
