Automotive Ethernet Protocol Analysis

The automotive Ethernet protocol mainly includes the OSI seven-layer model and the TCP/IP five-layer model. The OSI model divides the network into seven layers, namely the physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. The TCP/IP model divides the network into five layers, namely the physical layer, data link layer, network layer, transport layer and application layer. Both models aim to provide a standard network communication framework to enable communication between different devices.
