The Audio Video Bridging (*Gen1*) technology defines mechanisms (IEEE
|
|
\*
|
|
802.1BA) which allow to recognizes all the AVB-compatible devices in the
|
|
\*
|
|
network. Basically, AVB works only within a domain of directly connected
|
|
|
|
AVB-compatible network devices (i.e. bridges or endpoints). These
|
|
|
|
devices support precise synchronization (IEEE 802.1AS) and enable
|
|
|
|
reservation of their resources (IEEE 802.1Qat) for a data stream. This
|
|
|
|
way, and using special traffic shaping (IEEE 802.1Qav), deterministic
|
|
|
|
and low latency communication (stream) between AVB-compatible endpoints
|
|
|
|
though AVB-compatible network is
|
|
|
|
achieved.
