Software is beginning to simplify one of the hardest kinds of networking: wide-area networks that link up an enterprise’s remote sites, branch offices, and data centers. Now AT&T is getting in on the game.
On Wednesday, the carrier announced AT&T Software-Defined Wide Area Network (SD-WAN), a service that will control all of an enterprise’s WAN connections with the same software.
What software-defined networking has done for data centers, SD-WAN does for networks stretched across continents and oceans. As with SDN, the benefits should include lower costs and the ability to support new applications quickly without having to replace complex hardware and services.
