Tad Deriso, President & CEO of MBC said, "Infinera’s solutions have consistently enabled our network to respond to customers with speed, scale and reliability."

Infinera’s founding vision is to enable an infinite pool of intelligent bandwidth that the next communications infrastructure is built upon. Infinera is well-recognized in the technology segments of optical wavelength division multiplexing (WDM) transport and packet OTN switching across long-haul, subsea, metro and datacenter interconnect markets. The Infinera Intelligent Transport Network architecture delivers unparalleled scalability, convergence and automation for service providers to begin their journey to the Terabit Era while addressing growing bandwidth demands, increasing complexity and competitive pressures.

A Clean-Slate Design

Infinera pioneered a new approach for networks with photonic integration. This provides massive WDM capacity in a small power and space footprint to handle growing bandwidth needs. It also allows the transport system to scale in other dimensions – adding multi-layer packet-OTN switching without any performance compromise while injecting software intelligence. This clean-slate design differs from competitive solutions that use 10 gigabit per second (10G) and 40G platforms that may need to be retrofitted for scale or performance or completely refreshed within a couple of years. We believe that the Infinera Intelligent Transport Network offers strategic business value to customers and protects investments for the next decade.

The New Simplified Model of Layer C and Layer T

IT and network architectures are being drastically transformed. Scale and virtualization are fundamental trends driving this transformation. These trends are disrupting the old model of hierarchical, functionally heavy, ring fenced network comprising several layers of devices and giving rise to a simplified model of Cloud Services, and Intelligent Transport.

Cloud services are growing at a phenomenal rate. IT functions of compute, storage and network in a single super point of presence (POP) are being distributed to multiple Cloud datacenters . As a result, operators need to scale, simplify and increase flexibility in their networks. They are constantly seeking efficient ways to reduce their IT complexity. Network Function Virtualization (NFV) is enabling operators to migrate Layer 3-7 services like Security, Voice, CPE, and BRAS from standalone devices to software services on x86 hardware within Cloud datacenters, giving rise to the Cloud Services layer, Layer C.

Meanwhile, transport functions at the lower layers (layer 0 through 3) are converging as operators encourage vendors to design the most cost effective network elements, giving rise to an intelligent transport layer, Layer T. It combines packet services of Ethernet and MPLS technologies, digital functionality of OTN switching and optical transmission and switching with WDM and ROADM functionality. Software Defined Networking (SDN) abstracts the services and functions of Layer T and presents standardized application programming interfaces (APIs) such that control can be offloaded to Layer C.

All this is conceptualized as Infinera’s Intelligent Transport Network architecture, which is a judicious mix of packet, digital, and optical functions on a single, scalable, flexible, and programmable platform exposed to virtualized control and network applications via APIs using SDN.
