Networking

2. Network Organization
In-vehicle networking is creating a quiet revolution in automotive technology over the
past two decades.
A network organization is a collection of autonomous firms or units that behave as a
single larger entity, using social mechanisms for coordination and control.

3. Components of in vehicle network
❖The transport medium
❖Transceivers

❖Microcontrollers

4. Addressing
A network address is an identifier for a node or host on a telecommunications network.

5. Requirements for Bus System
❖Data transfer rate
❖Interference Immunity

12. Introduction to CAN bus system
The Controller Area Network (CAN) is a serial communication bus designed for robust
and flexible performance in harsh environments, and particularly for industrial and
automotive applications.

❖Low Cost
❖Centralized
❖Robust
❖Efficient and
❖Flexible

14. History
In 1986 BOSCH developed the CAN Protocol for the 1st
time.
