步骤104、单域APP从EMS中获取该SDN网元相关的链路资源，并且筛选出链路两端虚拟节点和虚拟接口都已存在于当前APP中的链路资源，APP再根据这些筛选出来的链路资源创建虚拟链路资源；Step 104: The single-domain APP obtains the link resources related to the SDN network element from the EMS, and filters out the link resources that exist in the current APP, and the APPs are filtered out according to the filtering. Link resources create virtual link resources;
步骤105、单域APP将新增的虚拟节点资源、虚拟接口资源和虚拟链路资源通过RESTFull接口发送给控制器；Step 105: The single domain APP sends the newly added virtual node resource, the virtual interface resource, and the virtual link resource to the controller through the RESTFull interface.
步骤106、如果当前单域APP具有北向的多域APP，单域APP将新增的虚拟节点资源、虚拟接口资源和虚拟链路资源通过RESTFull接口发送给此北向的多域APP；多域APP收到当前单域APP发送来的新增资源清单， 将创建这些资源的镜像资源，并且正确填写镜像关系字段。Step 106: If the current single domain APP has a northbound multi-domain APP, the single domain APP sends the newly added virtual node resource, virtual interface resource, and virtual link resource to the northbound multi-domain APP through the RESTFull interface; A list of new resources sent to the current single domain APP. The mirrored resources for these resources will be created and the mirror relationship fields will be filled out correctly.

步骤203、单域APP将需要删除的虚拟节点、虚拟接口和虚拟链路资源通过RESTFull接口发送给控制器以便控制器将相关设备从控制域中删除；Step 203: The single domain APP sends the virtual node, the virtual interface, and the virtual link resource that need to be deleted to the controller through the RESTFull interface, so that the controller deletes the related device from the control domain.
步骤204、如果单域APP还存在北向的多域APP，那么还需要通过RESTFull接口通知北向多域APP清理掉这些虚拟节点、虚拟接口和虚拟链路资源的镜像资源数据；Step 204: If the single domain APP still has a northbound multi-domain APP, the RESTFull interface is also required to notify the northbound multi-domain APP to clear the mirror resource data of the virtual node, the virtual interface, and the virtual link resource.

The southbound attribute overrides the attribute value of the corresponding virtual node; if the network element does not exist, it prompts the operation user whether to continue synchronization. If the user selects Yes, the single domain APP will delete the virtual node; if the user selects No, the single domain APP will terminate the synchronization, and the user maintains consistency through other maintenance means;
步骤403、单域APP以网元为单位通过RESTFull接口查询EMS中网元包含的接口数据，再将这些数据和对应的虚拟节点所有的虚拟接口进行比较，计算出新增的接口、需要更新属性的虚拟接口和需要删除的虚拟接口。对于新增的接口，单域APP为其创建对应的虚拟接口资源；对于需要更新属性的虚拟接口，单域APP将接口属性值覆盖给对应的虚拟接口资源；对于需要删除的虚拟接口，单域APP将会从数据库中对虚拟接口进行删除；Step 403: The single-domain APP queries the interface data included in the EMS in the EMS through the RESTFull interface, and compares the data with all the virtual interfaces of the corresponding virtual node to calculate a new interface and needs to update the attribute.

For the virtual interface to be deleted, the single domain The APP will delete the virtual interface from the database;
步骤404、单域APP以网元为单位通过RESTFull接口查询EMS中和网元相关的链路数据，再将这些数据和对应的虚拟节点所有的虚拟链路进行比较，计算出新增的链路、需要更新的虚拟链路和需要删除的虚拟链路。对于新增的链路，单域APP为其创建对应的虚拟链路资源；对于需要更新属性的虚拟链路，单域APP将链路属性值覆盖给对应的虚拟链路资源；对于需要删除的虚拟链路，单域APP将会从数据库中对虚拟链路进行删除。Step 404: The single-domain APP queries the link data related to the network element in the EMS through the RESTFull interface in the unit of the network element, and compares the data with all the virtual links of the corresponding virtual node to calculate the newly added link. The virtual link that needs to be updated and the virtual link that needs to be deleted. For a new link, the single-domain APP creates a corresponding virtual link resource for it; for a virtual link that needs to update the attribute, the single-domain APP overwrites the link attribute value to the corresponding virtual link resource; The virtual link, the single domain APP will delete the virtual link from the database.
步骤405、单域APP将同步带来的虚拟节点的变更(修改或者删除)、虚拟接口的变更(新增、修改和删除)和虚拟链路的变更(新增、修改和删除)通过RESTFull接口发送给控制器；Step 405: The single domain APP will change (modify or delete) the virtual node brought by the synchronization, change (add, modify, and delete) the virtual interface, and change (add, modify, and delete) the virtual link through the RESTFull interface. Sent to the controller;
步骤406、如果当前单域APP拥有北向的多域APP，当前单域APP还 会将上述步骤405中的变更情况同RESTFull接口发送给多域APP，由此多域APP处理相应的镜像资源使其和当前单域APP保持一致性。Step 406: If the current single domain APP has a northbound multi-domain APP, the current single domain APP is still The change in the above step 405 is sent to the multi-domain APP with the RESTFull interface, and the multi-domain APP processes the corresponding mirror resource to maintain consistency with the current single domain APP.
