MOST

question:

1. no interruptions, collisions, or delay in the transport

1. MOST

1.1 media oriented

MOST Application Framework is used in MOST, instead of a device oriented modeling.

MOST defines Functional units, called Function Blocks(FBlocks) which are standardized, object-oriented interfaces to the respective applications.

While CAN is used as the in-vehicle network for the engine management, the body electronics like door and roof control, air conditioning and so on,

MOST is optimized for multimedia applications. MOST can be used for controlling tasks, however its strength lies in the transmission of streaming data

with high bandwidth and without buffering.

1.2 ring

ring structure, up to 64 nodes, typical ring is 4 to 8 nodes

no interruptions, collisions, or delay in the transport of the data stream.

1.3 synchronous

transports not only data but also clock signal

clock signal does not need to be re-generated in sinks.

TimingMaster device generates the clock for the complete network.

All other devices - the TimeSlaves - synchronize their operation to this base signal.

1.4 topology

good points: bandwidth usage, ease of implementation, reduction in cable lengths

downside: if two disconnect, all are interrupted
