AUTOSARは、ISO、IEC、ITUと情報交換契約を結んでいません。
AUTOSAR文書には、ISO、IEC,ITU記述を全文引用することはできません。
WTO/TBT協定に基づき、国際的な調達は国際規格との差異を記述することにより文化依存しない仕様を目指します。
ISO、IEC、ITU文書を合わせて読むと技術内容は理解できます。　
CAN、OSEK/VDX OS、DIAGは、ISO定義を先に確認しましょう。　　
OSEK COM、OSEK NMなどはISOの規定から基本的な部分で定義を変えています。
変更している部分を仕様等で明記するか、ISOを改定するとよいでしょう。　

AUTOSARの参考文献欄の改定が進んでいません。　
Glossary用語定義の網羅性が低いです。
本文を読む前に確認するとよいかもしれません。
本文を読んでから確認してもよいかもしれません。

# Abstract Platformとの関係

Network Management 文書統合と状態管理構造の見直し。

<この項は書きかけです。順次追記します。>


## 文書変更(Document Change) 
>• Refined Partial Network Cluster handling
• Editorial changes

# 用語(terms)

|Term|Description|
|:--|:--|
|CanIf| CAN Interface module
|CanNm |CAN Network Management module
|CC |Communication controller
|ComM |Communication Manager module
|EcuM |ECU State Manager module
|DEM |Diagnostic Event Manager module
|Nm| Generic Network Management Interface module, this ist the abreviation used for this module throughout this specification
|NM |Network Management
|OEM |Original Equipment Manufacturer
|CBV| Control Bit Vector in NM-message
|PNC| Partial network cluster
|Bus-Sleep |Mode Network mode where all interconnected communication controllers are in the sleep mode.
|NM-Channel |Logical channel associated with the NM-cluster
|NM-Cluster |Set of NM nodes coordinated with the use of the NM algorithm.
|NM-Coordinator |A functionality of the Nm which allows coordination of network sleep for multiple NM Channels.
|NM-Message| Packet of information exchanged for purposes of the NM algorithm.
|NM-Timeout| Timeout in the NM algorithm that initiates transition into BusSleep Mode.
|NM User Data| Supplementary application specific piece of data that is attached to every NM message sent on the bus.
|Node Identifier |Node address information exchanged for purposes of the NM algorithm.
|Node Identifier List |List of Node Identifiers recognized by the NM algorithm.
|Bus|Physical communication medium to which a NM node/ecu is connected to.
|network |Entity of all NM nodes/ecus which are connected to the same bus.
|channel |Logical bus to which the NM node/ecu is connected to.
|Coordinated shutdown S|hutdown of two or more busses in a way that their shutdown is finished coinciding.
|Coordination algorithm |Initiation of coordinated shutdown in case all conditions are met.
|PN info |Represent the Partial Network information in a NM frame
|PN info range |Represent the length of a Partial Network information in bytes
|PNC bit |One bit which represent a particular Partial Network in the Partial Network Info Range
|PN filter mask|Vector of filter mask bytes defined by configuration container(s) NmPnFilterMaskByte per channel to filter relevant PNC requests for the PNC timer handling
|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. Note that for different PNCs it is possible to have different toplevel PNC coordinators. For the same PNC only one top-level coordinator is supported.
|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 request message|A top-level PNC coordinator transmits PN shutdown messages to indicate a synchronized PNC shutdown across the PN topology. A PN shutdown message is a NM message which has PNSR bit in the control bit vector and all PNCs which are indicated for a synchronized shutdown set to ’1’. An intermediate PNC coordinator which receive a PN shutdown message and forward the PN information as PN shutdown message on the affected channels. Note: An intermediate PNC coordinators has to forward the PN information of received PN shutdown message as fast as possible to ensure a nearly synchronized shutdown of the affected PNCs across the PN topology.
