Huawei & InterDigital Demonstrate Open-Standard, IoT-Platform Interoperability o Publishing of sensor device readings to the platform and discovery of these readings by applications. o Issuing commands to actuator devices. o Subscribing to the platform to receive notifications if/when devices publish new sensor readings. o Securing access to devices and data via authorization (i.e., access controls) enforced by the platform o Interworking between multiple transport protocols (e.g. HTTP, CoAP, MQTT) o Interworking between multiple content serialization formats (XML and JSON) Horizontal Testbed Program (OHTP), which addresses the need for re-usable platform capabilities, seemed a natural venue to test IoT platforms based on the oneM2M standard and to leverage the IIC’s aims of encouraging member companies to use horizontal platform capabilities. The IIC’s Testbed Working Group forum acted as a catalyst when InterDigital introduced its horizontal platform ideas. Huawei and other companies immediately recognized the opportunity to demonstrate that oneM2M is a good fit for industrial use cases and multi-vendor operating environments. Huawei and InterDigital representatives agreed on a three-phase plan, covering a period of one year, with progressively more demanding test cases. The progress reporting cycle mapped onto IIC’s quarterly member meetings which became a venue to bring additional IIC members into this work. This endeavor still represents one of the team’s primary aims. The physical configuration for the testbed involved Huawei hosting its IoT platform in China while InterDigital’s platform was hosted in the United States. Testing is being carried out across the globe, depending on the availability of individual testers. Some devices are physically located in Huawei’s facilities in China, while others are physically located in InterDigital’s labs in the United States. IIC I NTERACTIONS The oneM2M architecture maps quite well to the Industrial Internet Reference Architecture (IIRA) and the testing team confirmed that the two are consistent with one another. In the initial stages of the testing, there were some challenges due to slightly different interpretation of the specifications and an issue of access control to corporate networks. These were minor issues so there was no need to feed anything back to the oneM2M standard. oneM2M is also referenced in the Industrial Internet Connectivity Framework. Huawei plans to build on this early reference by contributing to both the IIC’s Interoperability and the Distributed Data Interoperability Management Task Groups. This work will demonstrate how oneM2M’s existing capabilities and the new features in its future release plan can help application P LANNING AND M ANAGEMENT F RAMEWORK This testbed was the result of Huawei’s and InterDigital’s existing relationships as well as the ecosystem partnering opportunities offered within the IIC.
