NTT Com develops network edge technology for connected vehicles and robots

NTT Communications (NTT Com) announced the development of core technology to adapt edge computing, a promising technology for accelerating data processing in IoT devices, to “mobile IoT devices” such as connected vehicles and robots .

The “Network Edge Solution” incorporating this core technology will be made available sequentially from December 20222, and NTT Com is looking for customers who can actually demonstrate this solution at their business sites. He plans to improve features based on feedback from customers who participated in the demo and the results of hearings on high-demand features. Large-scale services will be provided in fiscal 2023 as a new service to improve the performance of these mobile IoT devices.

This solution is achieved by using network edge technology, which enables edge computing at multiple locations near the mobile network (hereafter referred to as “edge locations”3) for the functions required by mobile IoT devices. For example, in a connected vehicle, the operating state is not uniform, and since motion occurs over a wide area, a variety of data must be processed, including sensor and location information sent by the large number of vehicles in circulation. This solution, however, allows several peripheral locations to cooperate with each other to achieve mass connectivity and distributed processing of large amounts of data, which makes it possible to adapt to the connected vehicle. Additionally, this solution provides individual functions using microservices4 architectures, allowing customers to select and use the functions they need based on their environment, such as on-premises computing or cloud computing.


The specific individual functions are as follows:

(1) Wide area distributed message queuing function

This feature enables data communication in response to startup and shutdown of IoT devices, changes in the communication environment, and movement over a wide area. Data buffering5 and data communication between edge locations are performed to cope with changes in the communication environment of mobile IoT devices and their movement over large areas. By temporarily holding data at edge locations and propagating it between edge locations as needed, data can be sent from nearby edge locations as soon as mobile IoT devices are ready to receive data. This eliminates the need for the customer’s system to manage the state of IoT devices and retransmit data based on when they start.

(2) Dispatcher function

This feature facilitates multi-cloud usage6, reducing costs and improving reliability. When mobile IoT devices are directly linked to cloud services, it is necessary to individually configure authentication credentials and communication destinations for all devices to operate in a multi-cloud environment. By integrating cloud service integration functions into this solution, edge locations can serve as hubs for endpoints, enabling a multi-cloud architecture with flexible data distribution. In addition, by combining with NTT Com’s “Flexible InterConnect”7 interconnection service, it is possible to connect to each cloud service in a closed area at low cost, enabling a more secure system architecture.

(3) Communication termination and authentication function

This feature provides data protection through authentication and encryption of communications using Mutual TLS8 (mTLS). IoT devices typically have difficulty authenticating clients using usernames/passwords etc. Therefore, mTLS, which authenticates both clients and servers using certificates, is effective in protecting highly confidential data from cyberattacks such as spoofing and man-in-the-middle. attacks9. In this solution, the network edge that terminates communication with mobile IoT devices supports mTLS, making it easy to implement security measures.
