A domestic research team has successfully developed new infrastructure technology to address the exploding data volume and changing Internet usage environment.

The Electronics and Telecommunications Research Institute (ETRI) announced that it has developed a data-centric networking (DCN)-based technology that enables the Internet to go beyond simple connections and provide optimal information processing while also enhancing security and search convenience.

The core of the new Internet technology developed by ETRI is to 'name and embed security (signature)' in data and to integrate networking and computing.

As new Internet technologies are applied, real-time data obtained from CCTV, black boxes, and Internet of Things (IoT) terminals will be given names.

Thanks to this, you can easily search for data and safely and automatically receive information as it is called in the application stage.

For example, fire departments can easily develop a notification service that receives data consisting of sensor location, sensor name, and occurrence time from sensors installed throughout the city and obtains relevant information in real time, enabling efficient response to fires.

Previously, cloud dataSensor data had to be collected and analyzed from a platform located at the center.

By applying ETRI technology, related information such as fire location and time can be automatically transmitted from the data name, eliminating the need for additional analysis processing.

By embedding security in data, it is now possible to detect any manipulation or errors that may occur during data transmission.

Thanks to this, malfunctions can be prevented in advance and hacking by unauthorized users can be prevented.

The research team simplified the network structure by integrating data transmission and computing.

This method optimally processes services based on requirements, such as allocating computing resources close to the sensor and fire station for urgent fire analysis and high-performance cloud computing resources remotely for processing for AI learning.

This is expected to increase data utilization and develop services more efficiently.

The research team applied the developed technology to the Korea Research and Development Network (KOREN) to demonstrate stable operation and prove its commercial viability.

In addition, the company revealed that it possesses the world's best data-centric network SW technology by recording forwarding performance, a router performance verification metric, at 300 Gbps on a general-purpose server.

The current Internet architecture, developed in 1975, is designed solely for data transfer, with host-to-host connections based on IP addresses.

This limits the mobility of mobile environments, the accuracy of content sources, and the integrity of data to ensure it matches the original.

In particular, recently, large-scale content consumption such as virtual and augmented reality (VR/AR), metaverse, transportation systems, remote control, etc., and services that cannot have errors or malfunctions, as well as basic data, are important.As artificial intelligence services proliferate, network innovation is needed to utilize data more efficiently.

ETRI is also actively pursuing service verification of new technologies.

Currently, we are conducting a verification of data distribution infrastructure for real-time environmental monitoring in Busan with Busan Metropolitan City and the Korea Institute of Science and Technology Information (KISTI), and we have confirmed that it can be applied to the V2X infrastructure of ETRI's autonomous driving shuttle AutoVe to improve the safety and efficiency of autonomous driving.

Kim Seon-mi, Director of ETRI's Network Research Division, said, "We have secured essential technologies for future digital infrastructure and verified their practical application, laying the foundation for a leap forward into a new internet era. We plan to further refine this technology by applying it to a variety of future-oriented environments."

This study was conducted as part of the Ministry of Science and ICT's 'Hyper-connected intelligent infrastructure source technology research' project.
