The integration of artificial intelligence and communication drives the intelligence of 6G networks,and the edge,as the close part of the network to access services,needs to provide low-latency intelligent services.A deep edge node architecture that realizes the integra-tion of communication,computing,intelligence and data at the edge of the network.The flexible,intelligent and programmable technologies that support deep edge nodes are analyzed.It is considered that the flexibility and intelligent programming technology of networks will play a key role in gradually achieving on-demand customization and self-optimization in the future.
