Samsung Electronics, in collaboration with SK Telecom, has developed and successfully demonstrated the first SDN-based Evolved Packet Core in Korea.

Unlike the conventional method of concentrating switching equipment in one place, distributed LTE switches are deployed across multiple regions, enabling the efficient transmission of large amounts of data while maintaining high quality.

The distributed LTE switch was developed based on Software Defined Networking (SDN), a next-generation communication technology. SDN is a distributed networking technology that separates the control part of network equipment from the data traffic delivery part to configure data transmission paths more efficiently.

Once SDN technology becomes widespread, mobile communication networks can be distributed and reconfigured more freely, making it advantageous for the application of new services.

Telecommunications operators can 혁신적으로 improve the perceived data quality of subscribers by setting optimal traffic paths based on subscriber or service type, and provide private network services to companies or public institutions without building new communication networks.

Data services can be provided near base stations along the shortest traffic path without passing through the central internet network, enabling various real-time data services of the 5G era, such as cloud gaming and remote driving.

In addition, SDN technology can distribute traffic concentration in LTE networks, thereby increasing network operational efficiency by relieving network load and rapidly handling failures.

Samsung Electronics NetworkPark Seong-yong, Senior Vice President of the Business Division Development Team, stated, “The introduction of core technologies such as SDN is expected to not only increase data speeds but also enable customized communication services optimized for the diverse needs of customers,” adding, “We will do our utmost to secure technological leadership in the construction of next-generation communication networks.”

Park Jin-hyo, Head of the Network Technology Institute at SK Telecom, stated, “Distributed networking technology is essential to efficiently accommodate surging mobile data traffic and provide differentiated future services to customers,” adding, “We will continue to take the lead in implementing next-generation mobile communication technologies.”
