In addition to the ISO Transport Protocol for CAN and FlexRay option for the more developed, there are a number of other transport protocols, we do not discuss here. On the one would be the VW transport protocols TP 1.6 and TP 2.0 to name. These transport protocols are used in part for the vehicles of the Volkswagen Group. It would have a special Transport layer for SAE J1939A specification of the commercial vehicle sector, which describes the on-and off-board communication via CAN. Last is still the Transport Protocol for LIN to mention. Since LIN know how CAN a range of data of up to 8 bytes per message, is the transport protocol for LIN virtually identical to the transport protocol for CAN, so ISOTP.
