Road vehicles — Communication on FlexRay — Part 2: Communication layer services

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.
