In-car Ethernet enters the road

Most cooperation releases automotive Ethernet into series production.

03/30/2012


MOSTThe Most Cooperation (Mostco) - the standardization organization for the leading automotive multimedia network Media Oriented Systems Transport (Most) - proudly announces that automotive Ethernet via Most is now making its way into the car and onto the roads. "With the current Most150 rollout, the Most Cooperation is adding the transmission of Ethernet protocol data to the established Most infotainment transport of audio and video within the car," explained Dr. Christian Thiel, Most Cooperation Administrator. "Thus, the Ethernet Channel of Most150 is equivalent to an IEEE802.x network. Most150 combines Ethernet technology with a networking technology that was designed to meet the stringent automotive requirements. Most provides the ideal network backbone for a broad variety of IP-based applications such as supporting apps on connected services and Internet access in general."
The Most network technology is extremely flexible, allowing star,
daisy-chain, tree, and other topologies implemented on different physical
layers such as POF (plastic optical fiber) and electrical physical layers:
coax and shielded or unshielded twisted pair (STP/UTP) copper wires. The
coax standard has recently been specified to serve other vehicle domains; it fits into the driver assistance domain, as this physical layer can provide bi-directional communication and power supply on the same
cable. Regarding content protection, HDCP (High-Bandwidth Digital Content
Protection) has been added in addition to DTCP (Digital Transport Content
Protection). With these, Most fulfills the present and will fulfill
foreseeable future copy protection requirements for upcoming rights
management and copy control systems.
Bandwidth for Ethernet transport exceeds 100 Mbit/s
The Most Ethernet Channel provides the necessary infrastructure to
implement all necessary protocols and mechanisms such as the Internet
Protocol (IP), the Transmission Control Protocol (TCP), or the Hypertext
Transfer Protocol (HTTP) which are required to support Internet access in
a distributed infotainment system. Simultaneously, MOST maintains other
essential communication features, such as synchronous and isochronous
channels for easy and efficient audio and video streaming. The Most150
network provides an efficient and easy to use solution for transmitting IP
traffic. Investigations on the throughput with the maximum bandwidth
allocated for the packet channel proved that a net bandwidth of over 107
Mbit/s can be achieved, showing that the maximum bandwidth of 142.8 Mbit/s can be used with efficiency of over 75%.
