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.
More companies are adopting APIs to connect systems and devices to meet customers’ digital needs, creating a flood of new applications and services. The result, though unintended, is that management and programmability of the physical and virtual network devices is a last minute item because of this fast path deployment mentality. Network Equipment Providers (NEPs) need a way to simplify operations and replace the traditional, slow, high-touch management model with a real-time, automated programmability approach.
Tail-f recognized that NEPs are under extreme pressure. On the one hand, increased competition is lowering revenue and forcing them to introduce new hardware and network services more quickly. On the other hand, infrastructure sprawl across physical and virtual devices compound the problem decreasing the ease and reliability of management of physical and virtual devices being developed. This results in decreased profitability and management.
Additionally, SDN and NFV are both exciting developments that offer benefits in terms of reducing vendor lock-in, improved scalability and elasticity of the network. But neither attacks the main bottleneck in terms of a well-defined data models and protocols.
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, ease of deploying and removing services, improved reliability and network flexibility. Ultimately, NEPs need a way to simplify operations (which ultimately reduce 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.
