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.

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.)
