用語(terms)

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'.
