About Tail-f

Who we are

Tail-f is a pioneer and leader in network programmability and data model-driven device management.



Tail-f has contributed heavily to the development of the NETCONF, RESTCONF and YANG standards in IETF. As the worlds of SDN and NFV have evolved, the benefits of using programmable devices with standard APIs and protocol interfaces have come a long way.

The problem is the network has evolved. Traditional methods of managing devices are costly and slow, especially with the sprawl of new devices needing to speak to other devices and objects. They don’t speak the same languages, and enhancements to the devices are often not supported. Tail-f realized that the key to fixing this situation is understanding the benefits of network orchestration in helping organizations reduce OPEX, east of deploying and removing services, improved reliability and network flexibility. Ultimately, NEPs need a way to simplify operations (which ultimately reduces network costs) and replace the traditional, slow, high-touch programmability model with a real-time, automated approach.

Seeing this need, Tail-f developed a unified data model-driven software framework solution for all management interfaces (NETCONF, RESTCONF, CLI, SNMP, WebAPI) supporting any user preference and described by the standard YANG data modeling language. Tail-f’s ConfD software framework leverages the NETCONF and RESTCONF protocols and YANG data models and a centralized configuration database to deliver unified, programmable management capabilities.

Today, creating new physical and virtual devices has never been easier or faster. NEPs can now expedite the development and deployment of new hardware in less time while meeting their business objectives. Tail-f is the first to deliver this flexible data model-driven framework that includes a variety of open standards-based management interfaces including NETCONF and RESTCONF. Tail-f’s ConfD solution is ideal for producing programmable network elements that meet the next-generation networking requirements for NFV and SDN technologies.
