Infinera specializes in Intelligent Transport Network solutions that are designed to continually improve the economics of networking by combining the scale of optics with converged digital switching and intelligent software automation. Service providers need to scale and improve the cost efficiency of multi-layer networks, including both the IP layer and the transport layer. The first step on this journey starts with the strong foundation of an Infinera Intelligent Transport Network™. Infinera leverages unique Large Scale Photonic Integrated Circuit (PIC) technology to provide customers with pools of service-ready optical bandwidth that enables faster time-to-revenue and greater profitability through network efficiency and the ability to rapidly deliver differentiated services without reengineering their optical infrastructure. Extending SDN to transport requires a hardware and software architecture that supports an ability to abstract these optical wavelengths into pools of optical capacity. Infinera's Intelligent Transport Network and DTN-X platform with PIC-based super-channels creates large, efficient pools of DWDM bandwidth that are combined with OTN switching, FlexROADMs and an intelligent software control plane to support full automation of the transport network. This abstraction and automation enables a simplified, programmable bandwidth services model, in contrast with other solutions that propose direct control of the analog transmission layer via heavy NMS systems which may hit scale and transaction rate challenges. Infinera’s SDN approach leverages this automation and includes the full software abstraction and virtualization of the transport layer through Open Transport Switch architecture, a lightweight software-based virtual transport switch that, when combined with an SDN control layer, can deliver programmable, open, and automated control of the transport layer. With that foundation in place it is possible to control and monitor both the transport layer and the IP layer via the OpenFlow protocol and other complementary web 2.0 protocols to speed multi-layer provisioning and optimization.
