Virtual Network Functions

AT&T FlexWare

Be responsive with AT&T FlexWare

Imagine a network that responds to your business needs in near real-time. A network that empowers your workforce and supports your customers more effectively by being more agile and efficient. Introducing AT&T FlexWare, a solution that allows your network to be as responsive as the business it supports.

Designed and deployed on the AT&T Integrated Cloud platform that leverages Software-Defined Networking (SDN) and Network Function Virtualization (NFV) technologies, AT&T FlexWare simplifies your network infrastructure while potentially lowering capital investments. You only need a single AT&T FlexWare Device at each site to run multiple AT&T-certified virtual functions from the best-of-breed vendors (AT&T FlexWare Applications).

AT&T FlexWare is modular: you can mix and match FlexWare Devices and Applications and deploy them to your various global locations much quicker than with traditional single purpose built network equipment models.

How It Works

NFV technology provides a simpler alternative to buying, configuring, and testing individual proprietary network appliances. With NFV, software replaces these appliances and is easily downloaded and deployed to industry-standard customer premises equipment at different locations within the network, like data centers or remote offices. To learn how this works, read the AT&T FlexWare Brief and the AT&T FlexWare Device Brief.
