KT introduces next-generation SDN controller to strengthen network stability.

KT announced on the 16th that it developed its own 'next-generation software-defined networking (SDN) controller' and applied it to its core Internet network (backbone network) to strengthen the stability of its network.

'SDN' refers to a centralized network automation technology that centrally integrates and controls equipment from various manufacturers based on software.

KT's 'next-generation SDN controller' automates control of key equipment on its Internet network.

KT said, “This solution is equipped with a function that automates all control commands, verifies the validity of commands before they are executed, prevents errors in advance, and recovers with one click if necessary. This function minimizes human intervention, prevents human errors, and allows for easier and more stable network operation.”

The next-generation SDN controller currently supports all standards (NETCONF/YANG) to control all devices regardless of the brand of network equipment. Network staff can create templates (sets of commands) to automate tasks with next-generation SDN controllers and simply set the order of command execution.

KT explained, “Through the development of the next-generation SDN controller, we have secured the basic technology for automating network operations,” and “In order to implement a network capable of autonomous operation, we plan to develop core AI technologies that recognize, analyze, and judge network situations and advance them so that even complex situations can be responded to in advance.”

KT Network Research Center Director Jong-sik Lee said, “We are confident that network stability will be further enhanced by automating all operations of the Internet backbone network with the next-generation SDN controller,” and “We plan to continue to lead the development of next-generation network technologies that will advance the transition to a fully autonomous network operation system.”
