In the realm of network automation, several open-source projects have gained popularity due to their robustness, flexibility, and the extensive features they offer. These projects help network engineers automate the configuration, management, and operations of network devices and services. Here are some of the most well-regarded open-source projects in network automation:
-
Ansible: A powerful IT automation tool that can be used for network automation. Ansible uses YAML for its playbook language, making it relatively easy to learn and use. It can manage configurations, deploy applications, and orchestrate complex workflows across network devices.
-
NetBox: A web-based infrastructure resource modeling (IRM) tool designed for network automation. It acts as a “source of truth” for networks, documenting and managing network resources like devices, connections, IP addresses, and much more. NetBox supports automation through its REST API.
-
Nornir: A Python-based automation framework that uses existing Python libraries such as Netmiko and Napalm for network tasks. It’s designed to handle large-scale network automation tasks more efficiently than simple scripts or ad-hoc command execution tools.
-
SaltStack (now known as Salt): Salt is a powerful configuration management and orchestration tool that can be used for network automation. It uses a central server that communicates with agents on network devices to execute commands and manage configurations.
-
Terraform: While primarily known for its capabilities in infrastructure as code (IaC) for cloud resources, Terraform can also be used for network automation. It can manage both physical and virtual network components across various service providers.
-
Batfish: An open-source network configuration analysis tool that allows users to model, analyze, and validate network configurations and behavior before deploying changes to production. It’s especially useful for preventing network outages and policy violations.
-
PyATS: Developed by Cisco, PyATS is a Python-based automation framework designed to help network engineers test their networks. It can also be used for network automation tasks, providing a versatile toolkit for network diagnostics and validation.
-
NAPALM: (Network Automation and Programmability Abstraction Layer with Multivendor support): NAPALM is a Python library that implements a set of functions to interact with different network device Operating Systems using a unified API. NAPALM supports several networking vendors and devices, facilitating the automation of multi-vendor networks.
These projects cater to different aspects of network automation, from configuration management and orchestration to testing and validation. Depending on your specific needs (e.g., device configuration, network modeling, or validation), one or more of these tools could be highly beneficial for automating your network operations.
