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.
