Netmiko vs ONOS

Netmiko is a free Python library for connecting to network devices and automating command-line tasks. It simplifies SSH connections and also documents supported Telnet device types. The library can collect output from show commands and make configuration changes while handling low-level device state. Its device list spans vendors and separates platforms by regular, limited, and experimental testing status. Regularly tested examples include Arista vEOS, Cisco IOS variants and NX-OS, Juniper Junos, and Linux. Documentation shows how to install with pip, connect to devices, run commands such as “show ip int brief,” and send configuration command sets that enter configuration mode. The project also links to API documentation, a secure copy tutorial, and guidance on using TextFSM. Optional extras support the bulk-encryption CLI and compatibility with Paramiko 4. Netmiko Tools can encrypt sensitive YAML values using Fernet or AES128; the guidance recommends protecting the key and keeping it out of version control. The project uses the MIT license, with bug reports and feature requests directed to GitHub issues.

ONOS is an open-source software-defined networking platform that provides a control plane for managing network components and running communication-service modules. Its µONOS architecture supports device configuration, monitoring and maintenance, forwarding-plane programming, topology validation, and fine-grained performance metrics. A symmetric cluster of identical instances distributes work across servers and is designed to handle instance failures; the architecture is described as highly available and dynamically scalable. Control and configuration interfaces include P4/P4Runtime, gNMI/OpenConfig, and gNOI, with gRPC connecting modular microservices. OpenFlow is the primary southbound protocol, and OVSDB, NETCONF, and SNMP are also named for device configuration. The microservices are designed for cloud and data center infrastructure using Kubernetes, with Docker images and Helm charts listed as deployment tools. A cloud-native web GUI uses Angular and gRPC Web to access backend modules. ONOS is free and published under the Apache License 2.0. It is aimed mainly at service-provider networks, with data-center and campus networks also identified as possible uses. Production downloads are recommended as a release tar.gz package or Docker image; the listed LTS release is X-Wing 2.7.0, dated July 16, 2021.
