|term|Description|
|:--|:--|
|API| Application Programming Interface
|BSW |Basic Software
|CWU |Car Wakeup
|EthIf| Ethernet Interface
|DET |Default Error Tracer
|IP |Internet Protocol
|NM |Network Management
|PDU| Protocol Data Unit
|PNL| Partial Network Learning
|SDU| Service Data Unit
|TCP| Transmission Control Protocol
|TCP/IP| A family of communication protocols used in computer networks
|UDP |User Datagram Protocol
|PNI |Partial Network Information
|UdpNm |UDP Network Management
|PDU transmission ability is disabled|This means that the NM message transmission has been disabled by the optional　service UdpNm_DisableCommunication.
|Repeat Message Request Bit Indication|UdpNm_SoAdIfRxIndication finds the Repeat Message Bit set in the Control Bit　Vector of a received NM message.
|NM PDU |Refers to the payload transmitted in a packet. It contains the NM User Data as well as the Control Bit Vector and the Source Node Identifier.
|NM Packet| Refers to an Ethernet Frame containing an IP as well as a UDP header in addition to the data (PDU) transmitted by the NM in the payload section.
|NM Message |Most abstract term referring to any single information item transferred within the methodology of the NM algorithm.
|Bus-Off state |Refers to a situation where no cable is connected to the Ethernet HW.
|Top-level PNC coordinator|The top-level PNC coordinator is an ECU that acts as PNC gateway in the network and that handles at least one PNC as actively coordinated on all assigned channels. If synchronized PNC shutdown is enabled, the top-level PNC coordinator triggers for these PNCs the shutdown, if no other ECU in the network request them.
|Intermediate PNC coordinator|An intermediate PNC coordinator is an ECU that acts as PNC gateway in the network and that handles at least one PNC as passively coordinated on at least one assigned channel. If synchronized PNC shutdown is enabled, it forwards received shutdown requests for these PNCs to the corresponding actively coordinated channels and starts their shutdown accordingly.
|PNC leaf node |A PNC leaf node is an ECU that acts not as a PNC coordinator at all in the network. It processes PN shutdown message as usual NM messages.
|PN shutdown message|A top-level PNC coordinator transmit PN shutdown messages to indicate a synchronized PNC shutdown across the PN topology. A PN shutdown message is as NM message which has PNSR bit in the control bit vector and all PNCs which are indicated for a synchronized shutdown set to '1'.
