Building a template for the future 6G network
Scientists propose an advanced 6G network architecture that combines SDN and NFV to overcome the drawbacks of traditional networks

In a recent study published in IEEE Transactions on Cloud Computing, researchers from Korea are proposing a combined SDN/NFV network architecture for 6G that seeks to introduce additional computational functions to existing network functions.

SDN is an approach to network architecture that allows the network to be controlled using software applications, whereas NFV seeks to move functions like firewalls and encryption to virtual servers. SDN and NFV can help enterprises perform more efficiently and reduce costs. Needless to say, a combination of the two would be far more powerful than either one alone.

“We expect our SDN/NFV-based infrastructure to be considered for the future 6G network. Once 6G is commercialized, the resource management technique of the network and computing core can be applied to AR/VR or holographic services,” says Prof. Jeongho Kwak of Daegu Gyeongbuk Institute of Science and Technology (DGIST), Korea, who was an integral part of the study.

The new network architecture aims to create a holistic framework that can fine-tune processing resources that use different (heterogeneous) processors for different tasks and optimize networking. The unified framework will support dynamic service chaining, which allows a single network connection to be used for many connected services like firewalls and intrusion protection, as well as code offloading, which involves shifting intensive computational tasks to a resource-rich remote server.
