A Call for Comment on DRAFT AES70-21-xxxx: AES standard for audio applications of networks – Open Control Architecture – Part 21: Using AES70 to manage AES67 and SMPTE ST 2110-30 media transport was published on 2026-01-09.
AES70 is a suite of standards for control and monitoring of devices in professional media networks. This standard defines an application of the Core AES70 specification for managing AES67 and SMPTE ST 2110-30 media transport connections, and related synchronization and clocking mechanisms. Other standards in the AES70 suite specify concepts and mechanisms, control and monitoring repertoire, control protocols, and other media transport management applications.
AES70’s intended range of use spans networks of all sizes. This includes mission-critical applications, high-security applications, IP and non-IP networks, and local and wide-area applications. AES70 can control real or virtual devices located on premises or hosted by cloud services. AES70 consumes little computing power and uses network bandwidth lightly.
AES70 is based on the Open Control Architecture (OCA), originally developed by the OCA Alliance.
