Editor's Notes
- Transport SDN can abstract and present a flat representation to applications with automated discovery, monitoring and provisioning
- So now we have one last step to achieve the part of our vision of “Intelligent Bandwidth”. <click> These platforms that converge WDM and switching can be used to create a digital node at any location needed in the network. Now that we have access to all services in digital format where needed, we layer on an intelligent control plane using GMPLS. <Click> The GMPLS intelligence creates a self aware transport network that has deep knowledge of every element in the network. Infinera has the largest GMPLS deployments in the world across integrated DWDM and OTN converged platforms. <Click> This GMPLS intelligence is combined with digital switching control over bandwidth to fundamentally “virtualize” the transport resources such that any service can be mapped into this flexible pool of bandwidth. <Click> On top of this we build a layer of application programming interfaces <Click> And on top of this we implement our industry leading unified DNA management system. This software building block approach also allows us to easily support SDN control as well. All of this combined we call the Digital Optical Network. <Click> An Infinite Pool of Intelligent Bandwidth that is Scalable, Efficient, Simple, Reliable and Programmable.
- This final example is about a service provider creating networks slices using SDN and delivering high capacity layer 1 virtual private networks as a service on a common infrastructure. Fundamentally, Network as a Service This approach actually slices up the network and can even virtualize the actual transport hardware itself on a port-by-port and card-by-card basis. This provides the security and garneted performance of a transparent private line service at extremely high capacities but in a very cost effective manner and The service provider can expose as much control as the to the end user as desired.
