AES67 Requirements and Recommendations
Clear-Com does not aim to verify Ethernet switch manufacturers or a customer's network topology. Though Clear-Com Engineering has tested specific switches for certain workflows, this information is for guidance only.
The standard AES67 network is a bridging compliance which allows any AES67 compliant device to participate with other compliant devices on a network in order to transport high quality audio over IP (AoIP.) Unlike Dante, this requires a more thorough understanding of the network topology since the mechanics are less automated.
Clear-Com has provided a thorough User Guide that explains what is necessary for a AES67 network, what is required and what has been tested.
AES67 Guide
IPA and IP-Transceiver Networking Guide
Features Required:
1Gb (or more) bandwidth for every port
Layer III - Can perform at or near wire speed, but also acts as a router because it has IP routing intelligence built in.
Switching capacity equal to 2x number of ports (Tx/Rx). To exemplify this, if you purchase a 10-port switch, it should have a switching capacity of 20 Gb/s.
EEE (Energy Efficient Ethernet) or Green Ethernet needs to be disabled.
QoS - Quality of Service prioritization of audio traffic.
Fiber to Copper conversion preferable using the SFP/mini-GBIC form factor.
IGMP snooping must be properly configured.
Recommended Features:
PTP Aware Switches (that support Boundary Clock or Transparent Clock Mode.)
Dedicated PTP GrandMaster Clock (separate from the IPA card.)
