Before revision: The new Layer-2 configuration protocols work with backwards-compatible extensions to the Ethernet 802.1 frame format; such minimal changes allows AVB devices to coexist and communicate in standard IT networks, however, only AVB-capable switches and endpoint can reserve network resources with admission control and synchronize local time to a master clock, which is required for low latency time-sensitive traffic.
