AT&T is embarking on an exciting journey to revolutionize its network by transforming itself into a software company running the largest and most intelligent programmable cloud on the planet. Indeed, the network of Domain 2.0 (D2) will be intelligent software systems and applications operating on general-purpose commodity hardware [1]. This transformation will not only drive down CAPEX, OPEX and help to configure our network with less human intervention, but it will also create significant opportunities to scale and monetize existing and new intelligent services. This transformation will enable AT&T's D2 to establish a new services ecosystem equivalent in concept to the application ecosystem adopted by the Apple iOS and Android. D2 will facilitate mass marketing existing and new services, and lower the barrier to entry for enterprise and small business customers to create new innovative services.
