What is ISO 21806-3 about?  

ISO 21806-3 is part three of the multi-series standard that specifies the conformance test plan (CTP) for the application layer for MOST, a synchronous time-division-multiplexing network, as specified in ISO 21806-2. 

ISO 21806-3 specifies conformance test cases (CTCs) in the following categories: 

• Device model 
• Data and basic data types 
• Registry management 
• Connection management 
• Error management 
• Diagnosis 

Note- 

Interoperability testing is not in the scope of ISO 21806-3. 

Who is ISO 21806-3 for? 

ISO 21806-3 on Media Oriented Systems Transport (MOST application layer conformance test plan is useful for: 

• Vehicle manufacturers 
• Car infotainment manufacturers and developers  
• Vehicle data services providers 
• Developers of multimedia and infotainment systems 

Why should you use ISO 21806-3?  

MOST enable 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. 

ISO 21806-3 provides a list that contains all information that is provided by the device manufacturer for conformance testing. ISO 21806-3 also includes remarks and references to corresponding CTCs. 

ISO 21806-3 specifies the timeouts to prevent deadlock situations during conformance testing. 

ISO 21806-3 lays out conformance test cases for power management and error management.
