SEOUL, Sept. 17 (Korea Bizwire) – LG Uplus announced that it succeeded in adopting “Software Defined Network/Open Flow (SDN/OF)” technology into commercial network for the first time in Korea together with local network device provider Ubiquoss.
The SDN/OF is a next-generation network technology enabling the network operators to separate software from “L3 Switch” and control hardware devices with separate server with software. As L3 switch finds the shortest way to transfer data efficiently in the complex structure of the Internet network, by separating software from the switch, operators can departmentalize data traffic and control certain traffic.
Up until now, in the landline networks, network devices from certain providers were used in the software-hardware integrated form. With the success of the technology, network operators can reduce their dependence on certain providers for their network devices and it will urge Korean small- and mid-sized network device manufacturers to join the R&D efforts to make new devices in the future.
With the SDN/OF technology, network operators can reduce the costly burden to change the devices by using existing hardware and running core software in a separate server. In addition, they can increase efficiency in operating the devices.
As the technology enables the operators to distinguish certain traffic in the central server, it can control and block the certain traffic in cases such as DDoS. Besides, the operators can add more functions in the existing network devices without the need to change the devices, which gives flexibility to them in the ever-changing network technology environment.
LG Uplus plans to apply the technology to some of its networks as a pilot application and expand to full wired landline networks.
Cho Chang-gil, director of LG’s Network Development Center, said, “After more than one year of our effort together with Ubiquoss, we finally succeeded in applying the SDN/OF technology in commercial equipment. We will keep our effort in developing network technology together with small- and mid-sized network device providers.”
