Service providers globally are converging on a control model to achieve the significant goal of automating service creation and assurance from data centers, through the network, to customer premises equipment. In this model, a centralized network controller delivers end-to-end network abstraction, automation, and service awareness, thus considerably simplifying the work of service orchestrators.
Realization of this vision, in practice, has many challenges however. In this post, we review the model and the challenges, and show a pragmatic three-phase approach to support the successful implementation of a service-aware network – a critical component of the complete solution. This approach builds on recent architectural work by service providers and standards bodies.
