Intent State Machine

The initial state where a business intent is expressed via a northbound Intent-Based API. The system ingests a declarative specification of the desired outcome—such as 'gold-level latency for trading apps'—without any device-level syntax. This state captures the raw, unvalidated policy object before any processing begins.

A pre-deployment verification phase where the Intent Engine checks the declared intent for logical consistency, resource feasibility, and policy conflicts. Intent Conflict Resolution algorithms detect overlapping or contradictory intents—such as competing bandwidth guarantees—using priority-based arbitration logic. Invalid intents transition to a rejected state.

The algorithmic process of converting the validated declarative policy into device-specific, low-level configurations. Network Configuration Synthesis uses formal methods to generate correct-by-construction CLI commands, NETCONF/YANG payloads, or API calls. This state bridges the gap between Policy Abstraction and vendor-specific implementation.

The operational state where the synthesized configurations are pushed to physical and virtual infrastructure via Network Service Orchestration. The system orchestrates cross-domain resources—compute, storage, and network functions—to instantiate the desired state. Successful activation transitions the intent to the active monitoring state.

A continuous validation loop where Telemetry Collection streams real-time network state data—counters, flow records, sensor metrics—into the Intent Assurance function. The system compares operational state against declared Service-Level Objectives (SLOs). Intent Drift detection triggers automated Remediation Workflows to restore compliance.

Intents are not static. Modification transitions allow policy updates—such as adjusting an SLO threshold—which re-enter the validation and translation states. The terminal decommissioning state cleanly removes all associated configurations and releases resources when a business intent is retired, ensuring no orphaned policies remain in the network.

The end-to-end management process that the Intent State Machine formally models. It encompasses the full journey of an intent from initial declaration and validation through activation, continuous monitoring, modification, and eventual retirement. Each phase maps to a specific state within the state machine, ensuring no operation occurs outside a defined governance boundary.

A pre-deployment verification process that acts as a critical guard transition within the state machine. Before an intent can transition from CREATED to FULFILLED, the validation engine checks for logical consistency, resource feasibility, and policy conflicts. A failed validation returns the intent to a draft state for human revision.

The operational phase where the state machine triggers the network configuration synthesis and orchestration engines. This state transition is only permitted after successful validation. The system pushes generated device configurations to physical and virtual infrastructure, moving the intent from a declarative specification to an enforced operational reality.

A continuous validation loop that monitors the FULFILLED state for intent drift. Using real-time streaming telemetry, the assurance function compares the network's operational state against the declared intent. If a deviation is detected, the state machine can automatically transition the intent into a REMEDIATION state to trigger corrective workflows.

An algorithmic mechanism invoked during the VALIDATION state transition when overlapping or contradictory intents are detected. Competing bandwidth guarantees or security policies are resolved using priority-based or negotiation-based arbitration logic. The state machine halts progression until all conflicts are resolved, preventing unstable configurations.

The self-regulating control system that the state machine enables. It continuously cycles through the MONITOR, ANALYZE, and REMEDIATE states. When telemetry indicates a violation of a Service-Level Objective (SLO), the closed-loop system automatically applies corrective configurations to restore compliance without human intervention.
