AVB Why AVB?
Audio Video Bridging (AVB, also called "Ethernet AV") is an emerging network standard built on IEEE 802 Ethernet, but designed to overcome Ethernet's traditional drawbacks for real-time streaming media: the absence of clocking and synchronization capabilities, and, most of all, lack of guaranteed quality-of-service (QoS)— the ability to always deliver audio samples and video frames in sync and on time. AVB remedies these flaws by providing bandwidth reservations (to ensure on-time delivery), a low-jitter master clock, guaranteed low latency (0.25 ms or less per hop with a maximum of 2 ms or less through 7 switches) and a timing mechanism for synchronization. AVB designates enough raw bandwidth to carry up to 200 audio channels through a single Gigabit Ethernet port, though, in practical use, a portion of this may be traded off to achieve advanced features. To achieve all of this, an AVB network segregates AVB traffic from standard Ethernet traffic and manages streams accordingly. That means that an AVB network can be interfaced with and carry data to and from a standard Ethernet network, but performance for streaming media can only be guaranteed amongst a group of devices all implementing AVB. Interest in AVB goes far beyond professional audio. With technology companies from Apple to Cisco to Alcatel-Lucent to Broadcom participating in the standard's definition, you can expect to see AVB receive wide acceptance, turning up at home in consumer devices, as well as in the professional media world. |
