A South Korean research time has developed a network technology that is able to maintain latency despite traffic amount. It has also developed a technology that is able to send data without any loss despite a network error. By doing so, it has established a foundation for next-generation network infrastructures.
Electronics and Telecommunications Research Institute (President Kim Myung-joon) announced on Tuesday that it has developed the world’s first DetNet (Deterministic Network) technology with an ability to transmit data at the capacity of 40 Gbps. It applied its technology to KOREN (Korea advanced Research Network), which is a hyper-connected intelligence research and development network and a leading test network for broadband, and succeeded in verifying the technology’s capability to transmit data back and forth between Seoul and Daejeon.
ETRI’s research team developed a technology based on DetNet that is currently going through international standardization within the IETF (Internet Engineering Task Force).
The team enhanced 8 Gbps DetNet core module that was developed for the first time in November last year and developed the technology that provides low latency of 4 msec and guarantees transmission of data without any loss despite errors at many points during the course. It has a capability to transmit data at 40 gigabits per second.

NIA (National Information Society Agency), SKT, Coweaver, and Woori-Net participated in the field inspection. Inspection covered data transmission between Seoul and Daejeon through ETRI’s system prototype and TSN (Time Sensitive Network) switch prototype developed by South Korean industries.
Technology developed by ETRI is expected to be used in various settings such as remote smart factory control, medical industry, drone control, VR (Virtual Reality), and hologram. It is perfect for 5G + vertical industry (industry that develops products and services different from mobile network) that requires real-time detailed work.
“We were able to secure ultra-low latency and lossless packet transmission technology that is a core technology in 5G and 5G+ early.” said Jeong Tae-shik who is the head of ETRI’s Ultra-Low Latency Network Laboratory. “By doing so, we have prepared a basis for positive economic effect and growth of convergence industry.”
Meanwhile, the institute transferred related technologies to South Korean transmission equipment makers Coweaver and Woori-Net back in February. By 2022, it plans to increase transmission capacity to 100 Gbps and capacity of packet optical transmission network system from 10 Tbps to 16 Tbps. It also plans to expand range of ultra-low latency and lossless performance nationwide and conduct studies regarding convergence between its DetNet technology and 6G.
