Overview of PDU router module and its functions in AUTOSAR system

The PDU (Protocol Data Unit) router module in the AUTOSAR system is a key component responsible for transmitting information between automotive electronic control units (ECUs). This module ensures efficient and reliable data communication between different software components by receiving, looking up routing tables, forwarding I-PDU (Interaction Layer Protocol Data Unit), and processing transmission requests. In the AUTOSAR system, each I-PDU has a unique identifier and is statically defined during the system design and configuration phase, ensuring the stability and predictability of the system.
