Final answer:
The Network Orchestrator or Controller within the Intent-Based Networking (IBN) model orchestrates policies and configures systems to align the network's performance with the business's intent.
Step-by-step explanation:
The element of the Intent-Based Networking (IBN) model that orchestrates policies and configures systems is known as the Network Orchestrator or Controller. This component is the brain of the IBN model and is responsible for interpreting higher-level business policies as provided by the network administrators into actionable configurations that are applied across the network. These configurations manage and automate the various devices and services within the network to meet the desired business outcomes. The orchestrator leverages sophisticated algorithms and often utilizes machine learning to continually verify that the network's performance aligns with the intent of the business policies.
To illustrate, when a network administrator specifies an intent, such as prioritizing video conference traffic over general web browsing, the Network Orchestrator interprets this intent and configures the network devices accordingly to ensure those policies are reflected in the actual network behavior. As the network environment changes or business needs evolve, the orchestrator automatically adjusts configurations to maintain alignment with the initial intent.
