What is 4D networking?

4D networking refers to a four-dimensional approach in network architecture, specifically incorporating the decision, dissemination, discovery, and data planes. This model aims to address the challenges of traditional networks by separating the control logic from data forwarding, enabling more flexible and scalable network management. 4D networking is a key component of Software-Defined Networking (SDN), which allows for centralized control and programmability of network resources.
