AES67 is a demanding application for data networks especially when the lower-latency modes are utilized. Not all network equipment is able to deliver the required QoS and performance. It is never easy and often impossible to determine, by looking and equipments specifications and data sheets, whether equipment will meet performance requirements.
There are a couple standards that may be useful starting points for determining how to test and specify network equipment for use in AES67 and other realtime applications.
RFC 2544 Benchmarking Methodology for Network Interconnect Devices
RFC 3918 Methodology for IP Multicast Benchmarking
These RFCs were created by the Benchmarking Methodology (bmwg) - http://datatracker.ietf.org/wg/bmwg/charter/. If anyone is aware of any other similar work, please let us know.
It would be great if we could get this work continued to be more applicable to AES67, Dante, CobraNet, Q-Sys, Livewire, RAVENNA and similar real-time networking systems.
