The carrier initially launched the network-based SD-WAN, aptly named SD-WAN – Network Based, to select U.S. customers in 2017.
Unlike its over-the-top (OTT) SD-WAN offering, based on VeloCloud’s technology, the network-based SD-WAN is dynamic. It includes dynamic application aware routing as well as built-in resiliency when architected through the AT&T Integrated Cloud (AIC), explained Josh Goodell, vice president for intelligent edge at AT&T in November.
“This will be the first time we have done a dynamic, network-based SD-WAN architecture,” Goodell said at the MEF17 event in Orlando, Florida.
Expanding the service means more businesses can bring software-defined networking (SDN) closer to the customer edge, said Roman Pacewicz, chief product officer, AT&T Business. “We can bring everything together edge-to-edge — from end points, to connectivity, to the cloud — wrapped in security,” he said in a statement.
Companies can mix and match connectivity for different site types, connecting VPN sites, Internet protocol security sites, and SD-WAN sites in a single VPN. So, for example, a company can migrate half of their locations to SD-WAN and dual broadband, while keeping the other locations on VPN, and they can maintain a single network from AT&T.
The product also allows enterprises to use MPLS features, and it can integrate with NetBond for Cloud, which provides dedicated connectivity to cloud platforms for enterprise customers. It can also be deployed as a virtualized function on a universal CPE through the carrier’s FlexWare platform.
The SD-WAN announcement comes as AT&T ramps up its other edge computing efforts. Earlier this week the company said it is testing edge computing in support of augmented reality (AR) and virtual reality (VR) services on mobile devices at its recently opened test zone in Palo Alto, California.
The test will look at reducing blurry and choppy graphics often associated with current AR and VR services running on mobile devices across multi-access edge computing (MEC) platforms.
