In the last few years Ethernet has gained a lot of momentum in the automotive world. At the same time, several automotive OEMs introduced Ethernet as On Board Diagnostic interface for production vehicles. In 2013, we see the second wave deployment with Ethernet being used in driver assistance systems (i.e. surround camera). The next logical step will be the use of Ethernet in Infotainment. Ethernet has already been used for many years in the Consumer and Professional Audio world, thus it suggests itself to look at the available solutions and evaluate whether they can be reused in Automotive. The presentation focuses at the specific challenges in the car and analyzes the benefits and drawbacks of the potential alternatives. We look at a number of potential scenarios, e.g. AVB class A, AVB class B, AVA, RTP and UDP.
