Dante is proprietary. As I understand it, it doesn't interoperate with anything (without incorporating licensed Dante IP in your product).
The open standards in a similar space (along various axis) as Dante are RTP/RTSP, AES50, AES67, AVB, AVB/MILAN. Often on dedicated networks. JackTrip is closest to RTP: lossless audio in UDP packets. Best-effort clock-recovery based on packet arrival times.
The main distinguishing features of all of these protocols are: - Ethernet Layer 2, or 3? - Packet formats - Method of time and clock distribution/clock recovery (PTP1 or 2, other) - Control plane protocols and management interface - Dependence on PTP and traffic reservation implementation on all intermediate Ethernet switches (AVB, Milan: yes, others: no)
MILAN (an AVB profile/subset) is the most direct competitor to Dante (aiming at the Plug-and-play capabilities of Dante). None the less Dante is actually a product offering, whereas MILAN is a technical standard.
From a technical standpoint clock distribution and control plane are the big differentiators.
