Netzwerkautomatisierung

Netzwerkautomatisierung (network automation) describes the use of software, APIs, and declarative policies to programmatically provision, configure, monitor, and troubleshoot network devices and services. It encompasses configuration management, change control, anomaly detection, and policy enforcement, aiming to reduce manual CLI work and improve consistency across routers, switches, load balancers, and firewalls.

Automation relies on a central controller or orchestrator that uses northbound interfaces to express intents and southbound protocols to enforce them on devices. Common models include Infrastructure as Code (IaC), intent-based networking, and closed-loop automation where telemetry and analytics feed feedback into policy updates. Core technologies include data models such as YANG, protocols such as NETCONF, RESTCONF, and gNMI, and open standards from OpenConfig, IETF, and IEEE. Inventory and topology sources, like NetBox, support a single source of truth.

End-to-end automation typically combines device-side agents or adapters, centralized orchestration, and a catalog of reusable workflows. Vendors provide platform-specific solutions, while open-source tools such as Ansible, NAPALM, and Terraform, and network-focused tools enable both configuration management and provisioning across diverse ecosystems. Security and governance remain critical, with role-based access, audit logging, encrypted channels, and policy compliance integrated into the automation pipelines.

Benefits include faster service provisioning, reduced human error, consistent configurations, scalable operations, and improved visibility. Challenges involve interoperability across devices and vendors, data-model maturity, change management, and the need for skilled operators and robust testing before production deployment.
