This paper proposes and explains about Controller Area Network Protocol, a serial communications protocol that was originally designed for the automotive industry, but has also become a popular bus in industrial automation as well as other applications. The CAN bus can be used in embedded systems, and can establish a network among microcontrollers. It is well suited for high-speed applications using short messages. Its robustness and reliability makes it suitable for the semiconductor industry. The Internet Protocol has proven to be a promising higher-level information carrier that can be ported to various network technologies and allow internet access of associated devices and to serve as a foundation for many middleware approaches. Methodologies and challenges faced for Porting the Internet Protocol to the CAN Protocol have been discussed.
