AVB is a set of IEEE standardized 802.1 extensions that provide better control over bandwidth and latency. This is important when you're playing multiple audio and/or video streams to multiple endpoints connected at different points in the network and they need to be low latency and still kept synchronized.
I've seen professional switches from a large vendor where the AVB license cost as much as the rest of the switch.
