Terms

terms(Acronyms and abbreviations)	Description
AA	AUTOSAR Adaptive Application
AP	AUTOSAR Adaptive Platform
API	Application Programming Interface
ASAM	Association for Standardization of Automation and Measuring Systems
BSW	Basic Software
DEXT	AUTOSAR Diagnostic Extract[2], describing diagnostic configu- ration of an ECU
DM	AUTOSAR Adaptive Diagnostic Management
DNS	Domain Name System
DoIP	Diagnostics over Internet Protocol (Communication protocol of automotive electronics according to ISO-13400-2[4])
DTC	Diagnostic Trouble Code according to ISO 14229-1[3]
ECU	Electronic control unit
EDR	Extended Data Record
HPC	High Performance Computing
HTTP	Hypertext Transfer Protocol
HTTPS	Hypertext Transfer Protocol Secure
IP	Internet Protocol
JSON	JavaScript Object Notation
MetaInfo	Meta-Information in the form of a key-value map, which is given from DM to external service processors.
ODX	Open Diagnostic Data Exchange (Standardized diagnostic data description format as of ISO-22901)
REST	Representational State Transfer
SDG	Special Data Group
SID	Service Identifier, identifying a diagnostic service according to UDS, such as 0x14 ClearDiagnosticInformation
SOVD	Service-Oriented Vehicle Diagnostics
TLS	Transport Layer Security
UDS	Unified Diagnostic Services
URI	Uniform Resource Identifier
URL	Uniform Resource Locator
DID	Data Identifier according to ISO 14229-1[3]. This 16 bit value uniquely defines one ore more data elements (parameters) that can are used in diagnostics to read, write or control data.
NRC	Negative Response Code used by UDS in the diagnostic re- sponse to indicate the tester that a certain failure has occurred and the diagnostic request was not processed.
Diagnostic Server instance	Diagnostic Server (DM) is intended to support an own Diagnostic Server instance per installed SoftwareCluster, see section 2.2 for a detailed description. Each of those Server instances has and manages its own resources and is responsible for dispatching and processing of diagnostic services.
Extended Data Records	Contains statistical data for a DTC. Extended data records are assigned to DTCs and maintained and stored by the DM.
Snapshot Record	Snapshots (sometimes referred to as freeze frames ) are spe- cific data records associated with a DTC and stored in the fault memory at a certain point of time during fault detection. The DTC specific data-parameters are intended to ease the fault isolation process.
SoftwareCluster	A SoftwareCluster groups all AUTOSAR artifacts which are rele- vant to deploy software on a machine. This includes the defini- tion of applications, i.e. their executables, application manifests, communication and diagnostics. In the context of diagnostics a SoftwareCluster can be addressed individually by its own set of diagnostic addresses.
SOVD entity	Entity in context of SOVD[1]
SOVD lock	SOVD locking mechanism as defined by [1]
UDS service	A diagnostic service as defined in ISO 14229-1[3].
Non-volatile Memory	In the context of DM, Non-volatile Memory refers to the persistent information over the shutdown of the DM process. This does not depend on HW details.
