# 用語(terms)
|Term|Description|
|:--|:--|
|CBV| Control Bit Vector
|FR |FlexRay
|NM| Network Management
|PN|Partial Network
|PNC |Partial Network Cluster
|PNI| Partial Network Information
|PNL |Partial Network Learning
|Bus-Sleep Mode |In this state no NM message is sent
|FlexRay communication cycle| Part of FlexRay communication schedule consisting of time slots (static or dynamic). Each FlexRay message is assigned to a specific time slot in one communication cycle.
|NM cluster |Set of NM nodes coordinated with the use of the NM algorithm.
|NM Message| Refers to the payload transmitted on the bus. It contains the User Data as well as the Control Bit Vector and may contain the Source Node Identifier.
|Normal Operation |In this state the node is sending periodic NM messages in order to keep a NM cluster awake
|Repeat Message State |This state ensures that transition, through a repetitive transmission of NM messages, to normal operation is visible for other nodes on the bus
|Repeat Message Request| Request (received internally or externally via an NM message) to transition back to the Repeat Message State
|NM Node |A ECU (electornic controll unit) which is connected to one or more NM clusters
|NM instance| A NM instance represents the current status of one NM cluster inside one NM node
|External Request| Communication request via received NM message
|Internal Request| Communication request via a NM node internal (request by application / uppler layer)
|Passive wakeup |A wakeup triggered by an external request
|Active wakeup |A wakeup triggered by an internal request
|PN info |Represent the Partial Network information in a NM frame
|PN info range| Represent the length of a Partial Network information in bytes
|PN bit| One bit with represent a particular Partial Network in the Partial Network Info Range
|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 act neither as top-level PNC coordinator nor as an intermediate PNC coordinator. It act as an ECU without a PNC gateway in the network and process PN shutdown message as usual NM messages.
|PN shutdown message| A top-level PNC coordinator transmits the PN shutdown messages to indicate a synchronized PNC shutdown across the PN topology. A PN shutdown message is an NM message where the PNSR bit (resides in the control bit vector) and all PNC bits (reside in the PN info) which are indicated for a synchronized shutdown set to ’1’. An intermediate PNC coordinator which receives a PN shutdown message forwards the PN information as a PN shutdown message on the affected channels. Note: An intermediate PNC coordinator has to forward the PN information of received PN shutdown message as fast as possible to ensure a synchronized shutdown of the affected PNCs across the PN topology at nearly the same point in time.
