Specification of Service Discovery, AUTOSAR 616, R22-11, CP, 20230421

Last updated at 2024-01-22Posted at 2023-03-15

AUTOSARは自動車用OSの業界団体規格です。　
業務で利用する場合には、会員になることを条件にしています。

2002年から20年経ち、当初の狙いの段階に近づいてきました。

MATLABでモデルさえ記述すれば、あとは自動生成だけでソフトが完成するところまで、あと一歩です。
Ethernet, UNIXが生まれて20年で大衆化したのと同じように考えると分かりやすいでしょう。　

AUTOSARの上で動く、クラウド対応のミドルウェアが出て、開発も運用もクラウドになれば、一気にAUTOSARは大衆化するでしょう。

用語(terms)

Term	Description
BswM	Basis software manager
ECU	Electronic Control Unit
DEM	Diagnostic Event Manager
DE	T Default Error Tracer
SD	Service Discovery
Sd	Service Discovery Module in AUTOSAR
SoAd	Socket Adaptor
SOME/IP	Scalable service-Oriented MiddlwarE over IP
SOME/IP-SD	SOME/IP Service Discovery
Service	A functional entity that offers an interface
Service Instance	A single instance of the Service
Offer	A message entry that offers a Service Instance
Stop Offer	A message that stops offering a Service Instance
Find	A message entry used to find a Service Instance
Event	A message sent by an ECU implementing a Service Instance to an ECU using this Service Instance.
Eventgroup	A logical grouping of 1 or more events. An Eventgroup is part of a Service.
Server Service	Provide a service
Client Service	Consumes a service
Server	A ECU which host ServerServices
Client	A ECU which host ClientServices
Endpoint Option	Endpoint Options are used to announce a tuple of unicast address and port
Multicast Option	Multicast Options are used to announce a tuple of multicast address and port
Unicast event	Events which are transmitted to a unicast endpoint by the ECU which host an SdServerService. The unicast endpoint is provided by a particular SdClientService which has subscribed to this SdServerService within the Endpoint Option referenced by a SubscribeEventgroup entry (see Consumed Eventgroup unicast endpoint)
Multicast event	Events which are transmitted to a multicast endpoint by the ECU which host an SdServerService. A multicast endpoint could be provided by the SdServerService (see Eventhandler multicast endpoint) and SdClientService (see Consumed Eventgroup multicast endpoint).
Eventhandler multicast endpoint	Term to describe the tuple of multicast address and port, which is pre-configured for a SdServerService per Eventhandler. If the threshold for subscribed Clients with different endpoint information has been reached, then the Server sends the corresponding events to this pre-configured multicast address and port. The Eventhandler multicast endpoint is announced via a Multicast option referenced by a SubscribeEventgroupAck entry
Consumed Eventgroup unicast endpoint	Term to describe the tuple of unicast address and port, which is pre-configured for a SdClientService per Consumed Eventgroup. A SdClientService which subscribes with this unicast address and port, indicates the SdServer to which endpoint, the cooresponding events shall be sent. The Consumed Eventgroup unicast endpoint is announced via a Endpoint option referenced by a SubscribeEventgroup or StopSubscribeEventgroup entry
Consumed Eventgroup multicast endpoint	Term to describe the tuple of multicast address and port, which is pre-configured for a SdClientService per Consumed Eventgroup. A SdClientService which subscribe with this multicast address and port, indicates the SdServer to which endpoint the corresponding events shall be sent. The Consumed Eventgroup multicast endpoint is announced via a Multicast option referenced by a SubscribeEventgroup or StopSubscribeEventgroup
Eventhandler multicast connection	Term to describe the usage of an established socket connection if a SdServerService provides the Multicast events via the configured Eventhandler multicast endpoint
Consumed Eventgroup unicast connection	Term to describe the usage of an established socket connection if a SdClientService receives the events via a Consumed Eventgroup unicast endpoint
Consumed Eventgroup multicast connection	Term to describe the usage of an established socket connection if a SdClientService receives the events via a Consumed Eventgroup multicast endpoint
