简介 Introduction

Service Discovery 模块， 即服务发现模块， 主要用于：

The Service Discovery module is mainly used for:

(1)探测外部是否有可用的服务， 定位服务位置。

(1)Detecting whether services are available and locating the service position.

(2)向外部提供可用的服务。

(2)Providing available services both internally and externally.

(3)实现发布/订阅机制， 以控制 Event 报文的订阅和发布。

(3)Realizing publishing/subscription mechanism to control the subscription and publication of Event messages.

Sd 模块位于 SoAd 和 BswM 模块之间， 和上述两个模块协作完成服务发现的功能。

The Sd module is between the SoAd and BswM modules, and works together with the two modules to complete the function of service discovery.

外部依赖 (External dependence)

功能描述 Functional Description

OfferService 功能 OfferService Functions

OfferService 功能用于向外部声明可以提供某种服务。当本地 ECU 作为服务器端提供某种服务时：

The OfferService function is used for declaring the specific service that can be provided externally. When the local ECU provides certain services as the server-side:

(1)该服务就绪时， Sd 模块会主动发送包含 OfferService Entry 的报文向其他ECU 表明当前有可用的某种服务。这种情况报文多播发送。

(1)When the service is ready, the Sd module will actively send a message containing the OfferService Entry to other ECUs in order to declare that certain service is available at present. Multicast transmission of messages is required under such case.

(2)当其它 ECU 发送 FindService Entry 主动寻找某种服务时， 本地 ECU 作为服务提供者， 向寻找服务的客户端发送 OfferService Entry， 表白可以提供某种服务。这种情况报文单播发送。

(2)When other ECU sends FindService Entry to actively search for certain service, the local ECU will send OfferService Entry to the client searching for the service as the service provider, in order to declare that certain service is available. Unicast transmission of messages is required under such case.

OfferService 功能实现 Realization of OfferService Functions

当服务可用或者不可用时， SWC 需要调用 BswM 的接口通知 BswM 某个服务可用/不可用， BswM 会调用 Sd_ServerServiceSetState(SdServerServiceHandleId，ServerServiceState)接口， 向 Sd 模块表明该服务的状态。其中 SdServerServiceHandleId 参数用于标识服务， ServerServiceState 用于标识服务状态。

When any service is available or unavailable, SWC should notify BsWM that the service is available/unavailable by calling the interface of BsWM. BsWM will call Sd_ServerServiceSetState(SdServerServiceHandleId，ServerServiceState) interface to declare the status of the service to the Sd module. In particular, SdServerServiceHandleId parameter is used for marking services while ServerServiceState for marking the service status.

Sd 模块会根据当前的状态向外发送 OfferService 或者 StopOfferService 报文。报文中会携带 SdServerServiceHandleId 代表的服务的信息（IP 地址， 端口号等）。其他节点可以利用这些信息定位到该服务， 以使用这些服务。Server 可以提供的服务在配置工具 SdInstanceSdServerService 中配置。

The Sd module will send OfferService or StopOfferService messages externally based on the current status. The message will carry the information about the service represented by SdServerServiceHandleId (IP address, port number, etc.). The information can be used by other nodes to locate and use the services. The services that the Server can provide can be configured in the configuration tool SdInstanceSdServerService.

FindService 功能 FindService Functions

FindService 功能实现 Realization of FindService Functions

当 SWC 作为客户端需要使用某种服务时， SWC 会需要调用 BswM 的接口通知 BswM 需要某个服务， BswM 调用 Sd_ClientServiceSetState(ClientServiceHandleId, ClientServiceState)接口， 向 Sd 模块表明需要某个服务。

When SWC requires certain service as the client, it will notify BsWM of the specific service by calling the interface of BswM. BsWM will call the Sd_ClientServiceSetState(ClientServiceHandleId, ClientServiceState) interface to declare to the Sd module about the specific service required.

Sd 模块会向外发送 FindService 报文。报文中会携带 SdServerServiceHandleId 代表的服务的具体信息（Service ID， 版本号等） 。其他节点理由这些信息判断自己是否可以提供这个服务， 可以提供时会发送 OfferService 通知寻找服务的客户端。

Sd module will send FindService message externally. The message will carry the specific information about the service represented by SdServerServiceHandleId (Service ID, version No., etc.). The information can also be used by other nodes to determine whether they can provide this service. If they can provide the service as well, these nodes will send an OfferService notification to the client looking for the service.

Client 需要的的服务（即需要寻找的服务） 在配置工具 SdInstance->SdClientService 中配置。

The services required by the Client (i.e. the service under search) are configured in the configuration tool SdInstance->SdClientService.

Eventgroup 功能 Eventgroup Functions

Eventgroup 功能实现 Realization of Eventgroup Functions

当 SWC（作为客户端） 需要订阅某个 Eventgroup 时， SWC 会调用 BswM 的接口通知 BswM， BswM 会调用 Sd_ConsumedEventGroupSetState(SdConsumedEventGroupHandleId， ConsumedEventGroupState)接口通知 Sd 模块。当 Sd 模块收到提供该 Eventgroup 的对应服务发送的 OfferService 报文时， Sd 模块会发送包含 SubscribeEventgroup Entry 的报文订阅 Eventgroup。

When SWC (as a client) needs to subscribe one Eventgroup, SWC will notify BsWM by calling the interface of BswM. BsWM will call Sd_ConsumedEventGroupSetState(SdConsumedEventGroupHandleId， ConsumedEventGroupState) Interface to notify Sd module. Upon receiving the OfferService message sent by the corresponding service providing such Eventgroup, Sd module will send a message containing the SubscribeEventgroup Entry to subscribe to the Eventgroup.

Client 需要订阅的 Eventgroup 在配置工具 SdInstance->SdClientService->SdConsumedEventGroup 中配置。

The Eventgroup that the Client needs to subscribe can be configured in the configuration tool SdInstance->SdClientService->SdConsumedEventGroup.

Eventgroup 管理功能 Eventgroup Management Functions

Eventgroup 管理功能简介 Introduction to Eventgroup Management Functions

当 Client 向 Server 订阅 Eventgroup 时， Server 需要管理订阅该 Eventgroup的客户端。

When Client subscribes Eventgroup from Server, the Server should manage the client that subscribes to that Eventgroup.

Eventgroup 管理功能的实现 Realization of Eventgroup Management Functions

当 收 到 Client 的 SubscribeEventgroup 报 文 后 ， Server 需 要 和 将 SubscribeEventgroup 报文中的信息（Eventgroup ID， 版本号， Service ID 等） 和配置中保存的信息作比较， 如果一致的情况下， 并且该 Client 之前不在订阅列表中， 则将该 Client 添加到订阅列表中， 向该 Client 应答 SubscribeEventgroupAck 报文。如果该 Client 之前已经在订阅列表中， 则用 SubscribeEventgroup Entry 中的 TTL 时 间 更 新 订 阅 列 表 中 的 TTL 值 。信 息 不 一 致 的 情 况 下 ， 应 答SubscribeEventgroupNAck 报文。

Upon receiving the SubscribeEventgroup message from the Client, the Server should compare the information in the SubscribeEventgroup message (Eventgroup ID, version No., Service ID, etc.) with that saved in the configuration. If the information of the above is consistent and the Client was not included in the subscription list, the Server will add the Client to the list and respond to the SubscribeEventgroupAck message to the Client. If the client has already been included in the subscription list, update the TTL value in the subscription list with the TTL time in the SubscribeEventgroup Entry. If however the information is inconsistent, respond to the SubscribeEventgroupNAck message.

当订阅时间到（SubscribeEventgroup 中携带的 TTL 计时时间到） 或者收到 Client 发送的 StopSubscribeEventgroup Entry， Server 需要将该 Client 从订阅列表中删除。

If the subscription time (TTL timing in the SubscribeEventgroup) expires or StopSubscribeEventgroup Entry is received from the client, the Server should remove the Client from the subscription list.

Server 提 供 的 Eventgroup （ 需 要 管 理 的 Eventgroup ） 在 配 置 工 具SdInstance->SdServerService->SdEventHandler 中配置。

The Eventgroup provided by the Server (i.e., the Eventgroup that needs managing) is configured in the configuration tool SdInstance->SdServerService->SdEventHandler.

RoutingPath 控制功能 RoutingPath Control Functions

RoutingPath 控制功能简介 Introduction to RoutingPath Control Functions

Sd 模块通过控制 SoAd 里面 SoAdRoutingGroup 的状态（Enable/Disable） ，从而达到控制 Event 的接收和发送的路径的通断， 控制 Event 的接收和发送。其中对 Event 发送路径的控制叫 Fan out 控制， 对 Event 接收路径的控制叫 Fan in控制。

The Sd module controls the on/off of the path for receiving and sending Events, as well as the receiving and sending of Event by controlling the status (Enable/Disable) of the SoAdRoutingGroup in SoAd. In particular, the control over the Event sending path is called Fan out control, and that over the Event receiving path is called Fan in control.

RoutingPath 控制功能的实现 Realization of RoutingPath Control Functions

Fan out 控制 Fan out Control

当 Client 订阅 Eventgroup 时， Server 根据 Client 发送的 SubscribeEventgroupEntry 中携带的信息在配置中找到与之匹配的 SdEventHandler， 根据 SdEventHandler 中的 SdEventHandlerTcp/SdEventHandlerUdp 找到对应的 SoAdRoutingGroup（取得 RoutingGroup ID） 。根据 SubscribeEventgroup Entry 中携带的 Endpointoption 信息以及配置中的 SdServerServiceUdpRef/SdServerServiceTcpRef 参数推导出该 Event 发送对应的 SocketConnection（取得 SoConId） ， 然后调用 SoAd_EnableSpecificRouting()或 SoAd_DisableSpecificRouting(RoutingGroupId， SoConId)， 来控制对应的 RoutingGroup。

When the Client subscribes Eventgroup, the Server will find the matching SdEventHandler in the configuration based on the information carried in the SubscribeEventgroupEntry sent by the Client, and further the corresponding SoAdRoutingGroup (obtains the RoutingGroup ID) based on the SdEventHandlerTcp/SdEventHandlerUdp in the SdEventHandler. According to the Endpointoption information in the SubscribeEventgroup Entry and the SdServerServiceUdpRef/SdServerServiceTcpRef parameter in the configuration, deduce the corresponding SocketConnection (obtains the SoConId) sent by the Event, and then call SoAd_EnableSpecificRouting() or SoAd_DisableSpecificRouting(RoutingGroupId， SoConId) to control the corresponding RoutingGroup.

Fan in 控制 Fan in Control

当 Client 向 Server 发送 SubscribeEventgroup Entry 向 Server 订阅某个 Eventgroup 时， Client 通过配置中的 SdConsumedEventGroupTcpActivationRef/SdConsumedEventGroupUdpActivationRef 参数找到对应的 SoAdRoutingGroup（取得 RoutingGroup ID） 。根据 OfferService Entry 中携带的 Endpoint option 信息以及配置中的 SdClientServiceUdpRef/SdClientServiceTcpRef 参数推导出该 Event 发送对应的 SocketConnection（取得 SoConId） ， 然后调用 SoAd_EnableSpecificRouting()或 SoAd_DisableSpecificRouting(RoutingGroupId， SoConId)， 来控制对应的 RoutingGroup。

When SubscribeEventgroup Entry sent from Client to Server subscribes one Eventgroup from Server, the Client finds the corresponding SoAdRoutingGroup (obtains the RoutingGroup ID) through the SdConsumedEventGroupTcpActivationRef/SdConsumedEventGroupUdpActivationRef parameters in the configuration. According to the Endpointoption information in the OfferService Entry and the SdClientServiceUdpRef/SdClientServiceTcpRef parameter in the configuration, deduce the corresponding SocketConnection (obtains the SoConId) sent by the Event, and then call SoAd_EnableSpecificRouting() or SoAd_DisableSpecificRouting(RoutingGroupId， SoConId) to control the corresponding RoutingGroup.

注意： 以上描述的所有功能能实现的前提是本端 ECU 的 IP 地址已指定， 即 Sd 模块的 Sd_LocalIpAddrAssignmentChg(SoConId， State)被调用过， 并且 State 为 TCPIP_IPADDR_STATE_ASSIGNED。

Note: The premise for realizing all the functions described above is that the IP address of the local ECU has been specified, that is, the Sd_LocalIpAddrAssignmentChg(SoConId, State) of the Sd module has been called, and the State is TCPIP_IPADDR_STATE_ASSIGNED.
