What is ISO 21806‑14 about?
ISO 21806‑14 is part 14 of the multi-series standard that specifies the technical requirements for the lean application layer for MOST, a synchronous time-division-multiplexing network.
The lean application layer includes a specification of the services available to control the configuration and behaviour of the network management.
The lean application layer covers the definition of:
- Node kinds
- Node addressing
- Data transport
- Network configuration
- Lean network services interface
- Network management, including connection management
- Diagnosis
- Timing definitions
Who is ISO 21806‑14 for?
ISO 21806‑14 on the technical requirements for the lean application layer for MOST is applicable to:
- Vehicle manufacturers
- Vehicle infotainment manufacturers
- Vehicle data services providers
- Developers of multimedia and infotainment systems
Why should you use ISO 21806‑14?
MOST enables the transport of high-quality service (QoS) audio and video together with packet data and real-time control to support modern automotive multimedia and similar applications. MOST is a function-oriented communication technology to network a variety of multimedia devices comprising one or more MOST nodes.
MOST is a synchronous time-division-multiplexing (TDM) network that transports different data types on separate channels at low latency. MOST supports different bit rates and physical layers. The network clock is provided with a continuous data signal.
MOST specifies mechanisms for sending anisochronous, packet-based data in addition to control data and streaming data. The transmission of packet-based data is separated from the transmission of control data and streaming data. None of them interfere with each other. MOST is a network that has mechanisms to transport the various signals and data streams that occur in multimedia and infotainment systems.
ISO 21806 series helps you implement the MOST communication technology into multimedia devices. It provides the conformance test plans for implementing related test tools and test procedures.
ISO 21806‑14 provides the lean application layer that includes a specification of the services available to control the configuration and behaviour of the network management. This will help you to manage and control the MOST.
ISO 21806‑14 gives guidelines for network configuration, network application interface, lean network services interface, network management and diagnosis.
