1 Scope
This part of ISO 10681 specifies the requirements for a communication protocol tailored to meet the requirements
of FlexRay-based vehicle network systems as specified in the FlexRay Communications
Systems Protocol Specification. As the communication protocol combines the network
layer and transport layer functionality (OSI layers 3 and 4), this part of ISO 10681 does not explicitly distinguish between these layer services.
The technical features of this communication protocol are as follows:
-
— transmit messages with known data length;
-
— transmit messages with unknown but finite data length;
-
— additional acknowledgement with retry mechanism;
-
— routing data on the fly;
-
— support of dynamic frame length.
