AVB

Layer 2
This system is designed with dual stack networking in mind: each piece of the system connects to two separate network stacks, ensuring that even if one network goes down, the redundant one keeps the data flowing. Networking runs over ethernet switches, but those switches must support the low latency AVB protocol stack at the firmware level.

Network bandwidth is the single biggest bottleneck for channel numbers. Using 10Gb networking would by far increase the theoretical maximum channel count, even at 96kHz or 192kHz. (e.g. from 250 channels on 1Gb to over 3000 channels on 10Gb.)

RAVENNA and AES67

Layer 3
Alternate to AVB, and allowing for using non specialized switches, is Ravenna, upon which the AES67 standard is based. This relies on IEEE 1588-2008, instead of 802.1AS. Also does dual stack networking, but doesn't require it like AVB. As for not using specialized switches, it does still want switches that natively support 1588-2008, but will work without it. Uses DiffServ VLAN QOS.
