FUNCTIONALITIES
The SOVD Vehicle Gateway is an implementation of the SOVD Server, which is defined by ASAM in the Service Oriented Vehicle Diagnostics (SOVD) as gateway for collecting, managing, and providing access to vehicle diagnostic data of HPCs and their related applications, as well classic ECUs.
Through the SOVD Vehicle Gateway, outer paties called SOVD-Clients can request diagnostic data using flexbile standard API SOVD-API. The SOVD Vehicle Gateway is responsible for receiving the requests from SOVD-Clients and redistribute them to specific vehicle components (SOVD-Component), which are responsible for the information.
The main features provided by the SOVD Vehicle Gateway are:
1. Implementation of the SOVD-API
2. Detection of SOVD-Components using MDNS: vehicle components, which should also implement the SOVD-API are detected via MDNS. The SOVD Vehicle Gateway can also provide the information to the SOVD-Client about which vehicle components are available.
3. Discovery by SOVD-Client using MDNS: the SOVD Vehicle Gateway is registered itself as a service in the MDNS and thus can be discovered by SOVD-Clients in a proximity case (same network)
4. Route requests between SOVD-Client and SOVD-Component: the SOVD Vehicle Gateway works as a bridge between a SOVD-Client and SOVD-Component, which it would like to communicate with.
5. Authorization mechanismus: all requests are protected with an authorization mechanismus, which will evaluate tokens generated by an Authorization Server and reject unauthorized requests
