Final answer:
NFV, SDN, and IoT are the three technologies that control network functions in an intent-based network.
Step-by-step explanation:
In an intent-based network, there are three technologies that control network functions to accomplish a desired intent:
- Network Function Virtualization (NFV): NFV is a technology that virtualizes network services, such as firewalls or load balancers, replacing dedicated hardware devices with software-based solutions that can be dynamically deployed and managed.
- Software-Defined Networking (SDN): SDN separates the control plane from the data plane in networking devices, enabling centralized management and programmability of network infrastructure. It allows network administrators to dynamically configure and control network devices through software.
- Internet of Things (IoT): IoT refers to the network of physical devices, vehicles, and other objects that are embedded with sensors, software, and network connectivity. In an intent-based network, IoT devices can provide real-time data and intelligence, enabling automation and optimization of network functions.
