This part of ISO 17215 specifies how services can be discovered and controlled. This functionality is located mainly in layer 5 of the OSI model. Both discovery and control are implemented using the scalable service oriented middlewire over IP (SOME/IP). Figure 1 shows a diagram of these aspects and their relation to other parts of this International Standard.

The general terminology defined in ISO 17215‑1 is also used in this part of ISO 17215.
