      What is Diagnostics over Internet Protocol (DoIP)?

      The era of Connected Cars, Infotainment and ADAS (Advanced Driver Assistance System) systems can be associated with explosion of ‘Big Data’ in the Automotive Industry.

      In-vehicle networking and communication between vehicles and road infrastructure, call for huge amount of data to be transferred at a very fast speed.

      In this new ecosystem, there is a strong business case for high-speed vehicle diagnostics and ECU reprogramming solutions.

      DoIP is the vehicle diagnostics solution that perfectly fits the bill! DoIP comes into picture as a supplementary to the existing network (mostly CAN) in a vehicle. However, it outsmarts CAN network by the virtue of its high-speed data rate (100 mbps)

      Simply put, DoIP is the set of diagnostic services made available on Ethernet data-frames. It is mostly used in combination of UDS (ISO 14229) based vehicle diagnostics protocol.

      Using DoIP, a diagnostic tester tool can communicate with a vehicle ECU over internet protocol. This ensures higher bandwidth as compared to a default vehicle network.

      What is the role of DoIP software stack in the new-age vehicle diagnostics and communication?

      Diagnostics over IP is a high-speed solution and supports remote vehicle inspection and repair. Due to several advantages offered by DoIP protocol stack, it is popularly deployed for the following automotive applications:

      • ECU Re-programming
      • Remote vehicle diagnostics
      • Measurement reading
      • Online data streaming to and from the vehicle


      Using DoIP protocol helps in saving time in ECU reprogramming as it is capable of handling huge data volumes. As it uses standardized communication protocol like UDS (ISO 14229), DoIP (ISO 13400) is quite flexible. Also its future-proof technologies enables DoIP to be deployed in various automotive use cases.
