Meanwhile, the work is continually going on and new features will be defined in the coming MOST Specification Rev. 3.1. One of these features is a multiport network interface controller that is able to allocate the true, full bandwidth of up to 150 Mbit/s in up to eight branches. This enables a streaming bandwidth of up to 1.2 Gbit/s and allows a variety of topologies. In addition, a remote network interface controller has been defined in a MOST network. It works autonomously without the need for a host controller, thus enabling the concentration of software in a centralized unit and tremendously simplifying the complexity of the "remote" nodes. Beyond, this article will show the evolution of the application framework based on new data types and a new xml schema based exchange format. Adding these features, MOST Technology turns out to be resilient and future-proof.
MOST is a multi-channel network that allows the parallel usage of all services for control data, streaming data and packet data through one network (figure 1). These services are easily synchronized, if necessary, in a highly deterministic way. Based on synchronous MOST frames, the transmission of both native streaming data and packet-oriented data, for example packetized elementary streams, is supported. The third generation of the MOST Specification ,  introduces MOST with 150 Mbit/s. It is supported for both Plastic Optical Fiber (POF) and Coax. MOST150 enables IP data communication, thus providing an automotive-ready Ethernet channel according to IEEE 802.3 with freely configurable bandwidth from 0 to nearly 150 Mbit/s. MOST is open to a broad variety of IP protocol based applications, including seamless integration of wireless mobile devices or car-to-car and car-to-infrastructure communication.
