scope:

1.1 General The scope of this document is to specify the requirements for diagnostic communication between test equipment and vehicle electronic components using Internet Protocol (IP) and the protocols TCP and UDP. This includes the definition of vehicle gateway requirements (e.g. to integrate into an existing computer network) as well as test equipment requirements (e.g. to detect and establish communication with a vehicle). The following aspects are specified to detect a vehicle in a network and enable communication with the vehicle's gateway as well as its sub-components during the various vehicle states. These features are separated into two types - mandatory and optional features. 1.2 Mandatory features - vehicle network integration (IP address assignment) - vehicle announcement and vehicle discovery - vehicle basic status information retrieval (e.g. Diagnostic Power Mode) - connection establishment (e.g. concurrent communication attempts), connection maintenance and vehicle gateway control - data routing to and from the vehicle's sub-components - error handling (e.g. physical network disconnect) 1.3 Optional features - DoIP entity status monitoring - DoIP entity firewall capabilities
