1.3 Feature description

1.3.1 Audio Video Bridging

AVB defines a group of network protocols for the distribution of time synchronized and low latency Audio & Video

streams over IEEE802 networks. By leveraging a combination of existing 802 network technologies along with

standards specifically designed for the purpose, AVB technology lays the ground work for un-paralleled guaranteed

media streaming over Ethernet networks. The overall concept of AVB is actually rather simple. Without getting into

too much detail, the three core protocols specify:

- Timing and synchronization

- Bandwidth allocation through the Stream Reservation Protocol (SRP)

- Traffic shaping to ensure that low priority Ethernet traffic does not interfere with AVB traffic

Engineered from the ground up for media streaming applications, AVB has a definitive edge over legacy Ethernet

technology in the sense that it allows bandwidth allocation and priority rules based on timing. Unlike similar audio

over IP (AOIP) technology, AVB will dynamically assign and defend bandwidth allocation for AVB streaming thanks to

the concept of Stream Reservation Protocol (SRP).
