SDP is Service Delivery Platform and is a virtual private cloud platform, which deliver services end-to-end. SDP can be provided to high-value customers as they don’t like to have their data being stored at the places they cannot control and they don’t want their data being analysed by third party who does not get their authorization. Any original service on SDP is delivered directly to the user regardless of where the user is and regardless of where the original service is running, thus achieving bordeless end-to-end service delivery.
We can treat any event or object such as an action, a set of data or a result as a service, and these services can be directly delivered to the user through SDP.
Examples:The vibration, temperature and other sensors on the industrial production line provide the equipment operating condition monitoring service for maintenance unit; the smart vending machine provides out of stock threshold warning service for the upstream suppliers of supply chain; the smart gateway in smart lighting system provides the property management unit with energy consumption monitoring services at various places…
It includes all smart devices and service terminals, and each LTSU provides its own unique service in a specific application scenario (for example, a temperature sensor installed near a production line provides real-time temperature data of the production line for the operation and maintenance platform and the enterprise operation platform).
For some status data generated by the local device, the final processing result or processed data can be delivered end-to-end in the form of a service.
Most of them are service units outside the production environment. The major work is to provide computing capability support for edge devices and provide technical services such as AI and VR.
In commercial applications, the security requirements of data are relatively high, and most of the production data cannot be uploaded to the third-party cloud platform (for example, the display data of electronic price tag etc.). Therefore, SDP provides an end-to-end service delivery with the establishment of end-to-end delivery channels between different cloud service units and between them and various production environments through LongTooth™ distributed IoT communication technology. The service is delivered directly between the service provider and the serviced party through this direct connected tunnel.
It is a layer in which all specific applications are located, that is, a layer that is finally presented to device users and interoperates with other services and applications.
Examples: Specific applications of operation dashboard, capacity scheduling, dynamic monitoring of equipment operation status etc. in Industrial Internet of Things; while in the smart toilet project, the municipal regulatory operation department knows the service situation of each health service provider through operation dashboard; and remote maintenance operation in a vending machine...
The core task of exchange layer is to realize direct delivery of services for parties at both ends. There are various modular services on the platform, and the service user can directly select the service that s/he needs, and then the service provider can directly deliver the service through SDP.
All services are not stored on SDP, but stored locally at the service provider, which only has a service addressing relationship with SDP. After the service addressing is completed, the service is delivered directly by the provider and not forwarded by SDP.
The service unit of service layer provides user various services such as data computing, data analysis and action response . A device can be at both the service layer and the application layer and thus no specific location, which entirely depends on its role in the application scenario.
Examples: LTSU (LongTooth™ Service Unit) in Industrial Internet of Things provides equipment operating condition service for equipment maintenance unit, and the equipment maintenance unit provides remote diagnosis service for the equipment; Each LTSU can provide basic data for ICSU (Inter Cloud Service Unit), and ICSU provides commercial guidance service for LTSU through data integration analysis...
