The difference between UDS on IP and UDS on CAN

The difference between UDS on IP and UDS on CAN

UDS on IP (LAN/WLAN):

• UDS application layer (ISO 14229-5)

• DoIP transport layer (ISO 13400-2)

• Ethernet physical layer (IEEE 802.3)

UDS on CAN (CAN):

• UDS application layer (ISO 14229-3)

• CAN transport layer (ISO 15765-2)

• CAN physical layer (ISO 11898)

So ISO 14229-5 standard defines implementation of UDS on IP and ISO 14229-3 standard defines implementation of UDS on CAN.

In other words, UDS on IP is more efficient than CAB Bus in many aspects, such as greater latency time of data transmission, able to handle larger amounts of data, data format makes it less prone to error and more.
