Conventional IEEE 802.3 Ethernet is unable to meet the connectivity and multimedia requirements of next-generation automotive infotainment networks. Its limitations include lack of precision timing mechanism, lack of QoS and no mechanism to prevent network congestion. Ethernet Audio Video Bridging (AVB) overcomes these limitations by providing timing synchronization, eliminating buffer delay through the network and creating resource reservation. AVB defines a set of technical standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Audio Video Bridging Task Group of the IEEE 802.1 standards committee. AVB is well positioned to be the technology of choice for building next-generation automotive infotainment networks. It offers several advantages such as, easy to manage, built on IEEE standards, affordable and Ethernet-based, single network for all media.
