Diagnostic MessagesDoIP Basics

TCP: Diagnostic Message (SA, TA, UD1))TCP: Diagnostic Message Positive Acknowledgement (SA, TA, ACK Code, …)2)1) UD = User Data, contains the Diagnostic Request/Response2) Only sent by a gateway after receiving, processing and copying the message correctly into the destination network transmission bufferTCP: Diagnostic Message (TA, SA, UD)

Ext. test equipment DoIP ECU/Gateway

DoIP Port UsageDoIP Basics� The first edition of the standard only specifies one port number both for TCP and UDP frames (13400)Ext. test equipment (“Tester”) DoIP entity(“ECU”, “Gateway”)UDP Port: 13400(“UDP_DISCOVERY”)UDP Port: <dynamically assigned>UDP Port: <dyn. assigned 49125..65535>(“UDP_TEST_EQUIPMENT_REQUEST”)

Unsolicited DoIP messages(e.g. Vehicle Announcement Message)“DoIP routing Messages” (Requests)

Control Commands, Information Requests

“DoIP routing Messages” (Responses) TCP Port: 13400 (unicast)(“TCP_DATA”)TCP Port: <chosen automatically>UDP Port: 13400(“UDP_DISCOVERY”) Responses
