Road vehicles - Diagnostic communication over Internet Protocol (DoIP) - Part 2: Transport protocol and network layer services

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
