Communication over the CAN bus is done via CAN frames. Below is a standard CAN frame with 11 bits identifier (CAN 2.0A), which is the type used in most cars. The extended 29-bit identifier frame (CAN 2.0B) is identical except the longer ID. It is e.g. used in the J1939 protocol for heavy-duty vehicles.
Bus topology networks are relatively inexpensive to build which is another advantage. CAN-bus networks quickly made point-to-point wiring obsolete which reduced wiring cost, complexity, and weight.
Bus Topology Simple layout and cheap but vulnerable to failure and only suitable for low traffic volumes. Not used for office networks today, but can still be found within some consumer products.

IV. R ESULTS : A CAN BUS N ETWORK In this paper, a CAN bus network is considered. It is divided into multiple sections called 1 to 7 with lengths 5 , 8 , 13 , 26 , 8 , 18 and 22 respectively. The cables that connect the electronic functions to the bus for access to the network are denoted by 10 to 60 with length 5 .
Further to the "vehicle with CAN" point, the vehicle may or may not be using CAN to transport data between the various black boxes on the car (other protocols are available and the manufacturer can use what they like); and it may or may not support CAN on the OBD-II port (the OBD-II standard gives a choice of three protocols, of which CAN is just one - that's why it's a 20-pin connector, so ...
