The control hierarchy for SDN networks is converging toward a three-tier structure. This paper describes this three-tier control hierarchy, which includes a service orchestrator, a network controller, and multiple domain controllers. It also describes the benefits of using a three-tier structure, which include faster innovation, a stable ecosystem of collaborating parties, and flexibility to replace building blocks with minimal effort and without vendor lock-in.
Selecting the right IP/optical network controller is critical for end-to-end service delivery in a multilayer, multivendor, multidomain network. This paper lists a set of questions that we suggest service providers ask suppliers when determining whether the solution can truly deliver comprehensive, accurate visibility and control.
Without understanding the connectivity and dependencies between network layers, you are likely unaware of the wasted CapEx and OpEx spent on deploying, operating, maintaining, and troubleshooting the network. The Sedona NetFusion solution addresses these issues with products that focus on integrated discovery and control of the IP/MPLS and Optical layers.
Our customers are experiencing a network revolution with a world of multilayer, multivendor, multidomain information at their fingertips. Using NetFusion’s discovery and visibility capabilities, they have reported 10 common use cases and identified why these solutions are critical to business.
The NetFusion Intelligence and Automation App Platform is the first control platform that converges the layers, automatically discovering multivendor, multidomain topology and traffic for both Optical and IP/MPLS layers, as well as the cross-layer connections between them.
Based on our recent webinar with Light Reading and Nokia, this white paper provides a detailed look at the new SDN-based IP and optical integration renaissance, including the market drivers, technology enablers, primary applications and use cases, leading operator success stories, and work yet to be done.
The NetFusion Intelligence and Automation App Platform enables multivendor discovery of the Optical layer, IP/MPLS layer, and the cross-connections between the two layers. The accompanying NetFusion Explorer UI enables you to visualize and explore this multilayer network model in near realtime, showing optically-aware IP/MPLS routing and conversely, IP/MPLS-informed optical paths.
This paper focuses on requirements for the NBI of Optical domain controllers in a multilayer architecture.
