With the explosion of demand for connectivity and multimedia in the automobile, the need for standards-based A/V networking that can be easily deployed is now well-established. The IEEE 802.1 Audio/Video Bridging (AVB) task group and the IEEE 1722 Layer 2 Transport Protocol Working Group for Time-Sensitive Streams have developed a series of network enhancements that provide the components for highly reliable audio and video applications. The AVnu Alliance has taken these standards, documented a profile for automotive use, and developed certification tests in its automotive Certification Test Subgroup (CDS). This paper outlines these new technologies and their benefits when used for in-vehicle applications.
