Audio Video Bridging

Audio Video Bridging (AVB) is a common name for the set of technical standards which provide improved synchronization, low-latency, and reliability for switched Ethernet networks. AVB embodies the following technologies and standards:IEEE 802.1AS-2011: Timing and Synchronization for Time-Sensitive Applications (gPTP);
IEEE 802.1Qav-2009: Forwarding and Queuing for Time-Sensitive Streams (FQTSS);
IEEE 802.1Qat-2010: Stream Reservation Protocol (SRP);
IEEE 802.1BA-2011: Audio Video Bridging (AVB) Systems;
IEEE 1722-2011 Layer 2 Transport Protocol for Time Sensitive Applications ; and
IEEE 1722.1-2013 Device Discovery, Enumeration, Connection Management and Control Protocol (AVDECC).
