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.


Selecting the right IP/optical network controller is critical for end-to-end service delivery. There is no room for capability gaps in the solution and we encourage you to carefully consider your options. We suggest asking suppliers the following questions to determine whether the solution can truly deliver comprehensive, accurate visibility and control in a real-world multilayer, multivendor, multidomain network. 

What’s the difference between the challenges faced by Telecom service providers and cable operators in their high-capacity backbone and metro networks? Not much, actually. We learned this at the CableLabs Winter Conference in Orlando this week.

In a recent interview, Google’s Head of Datacenter Fabric and Inter-DC Networking, Vijoy Pandey, urged service providers to stop waiting for SDN/NFV standards to emerge. Instead, he advised, “Just go ahead and build this stuff… start deploying a few things, and you’ll see the benefits right away.” Well, I couldn’t agree more.
