RAVENNA

Open Technology & Standards

Open Technology

Unlike most other existing networking solutions, RAVENNA is an open technology standard without a proprietary licensing policy. Interested parties are invited to participate in the ongoing development activities. In order to emphasize this open approach, ALC NetworX has  teamed-up with renowned companies from the Pro-Audio market to present a variety of RAVENNA-powered devices.

Standard Protocols

RAVENNA is an IP-based solution. As such it is based on protocol levels on or above layer 3 of the OSI reference model. All protocols and mechanisms used within RAVENNA are based on widely deployed and established methods from the IT and audio industry or comply with standards as defined and maintained by international standardization organizations like IEEE, IETF, AES and others.

AES67 (X192)

In autumn 2010 the AES inaugurated the X192 Task Group on High-performance Streaming Audio-over-IP Interoperability. The goal was to define an interoperability standard for transport of high-quality audio over networks based on the Internet Protocol (OSI layer 3) which would allow various existing IP-based network solutions to interoperate with each other.

The standard will be useful for distribution within broadcast, music production and post-production facilities but will also be applicable for commercial audio applications including fixed and touring live sound reinforcement.

On September 11th, 2013, the AES has finally published AES67-2013, the "AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability".

Basically, AES67 is a subset of the RAVENNA technology framework. Consequently, AES67 will become a RAVENNA operational profile which would allow all RAVENNA-enabled products to interoperate with AES67-compliant devices from other manufacturers. However, RAVENNA technology reaches far beyond the AES67 definitions and offers superior functionality and performance capabilities.
