Are you ready to move to a Transport SDN programmable network? Infinera’s Transport SDN solutions bring the power of SDN to the transport layer, from long-haul and subsea to metro access.

With customer bandwidth requirements increasing exponentially, and a plethora of diversified service offerings in metro packet-optical networks, Infinera’s Transport SDN solutions are designed to exploit maximum value from the network while keeping costs to a minimum. They offer the ability to provision and deliver intelligent next-generation services and help service providers transform their networks for maximum efficiency.

SDN Foundation: Programmable Transport Networks

Transport SDN starts with highly scalable, flexible, and programmable networks. The true power and capability of Transport SDN can only be realized when the underlying transport network is fully programmable at every layer, from the packet layer all the way down to the optical layer. Infinera delivers unparalleled transport agility and flexibility, combined with automated end-to-end service provisioning from long-haul and subsea to metro core and metro access.

Infinera's Intelligent Transport Network leverages Photonic Integrated Circuit (PIC) technology to support super-channels that create large, efficient pools of programmable DWDM bandwidth. In addition, features such as packet-aware transport, OTN switching, CDC ROADM switching, Instant Bandwidth and FlexCoherent provide network operators with an unparalleled level of transport agility and flexibility, forming a solid foundation for SDN-based control and programmability.

Infinera’s TM-Series forms the foundation of the Intelligent Transport Network within Metro Packet-Optical Networks. The TM-Series delivers highly flexible and configurable capabilities, combining Layer 0 and Layer 1 optical transport networking with Layer 2 and Layer 2.5 Ethernet and MPLS-TP networking in one single system, and a software architecture that enables fully open programmability across all layers.

SDN Solutions

Infinera’s first deployed Transport SDN solution, comprising the Open Transport Switch (OTS) software and the Intelligent Transport Network, unleashes the power of abstraction to offer a real-time on-demand programmable bandwidth service model. This solution’s cutting-edge yet simplified approach was built from the ground up with an IT mindset and allows service providers to provision and deliver innovative services and automate their operations while enabling optimal resource utilization within a multi-layer network.

Infinera’s OTS is a lightweight software construct that offers an open Web 2.0 API that facilitates easy and rapid integration of Infinera’s Intelligent Transport Network into the operator’s SDN framework. With OTS, network operators can realize dynamic programmability of optical transport services and resources and leverage the full set of software-controllable capabilities the converged packet/OTN/WDM network has to offer, whether it be enabling new innovative service capabilities, streamlining operations, or facilitating multi-layer resource optimization.

Infinera’s SDN solutions for metro networks follow the same principle of abstracting key network functions through an open API, enabling integration with any SDN controller. Infinera provides SDN-ready control capabilities tailored to metro networks, including a Path Computation Engine (PCE) module designed to work across Layers 0, 1, 2 and MPLS-TP for automated end-to-end service provisioning.

Finally, Infinera has demonstrated a range of SDN applications including virtual routing functionality that enables metro packet optical transport switches (EMXP) to perform certain functions previously found in routers, and SDN-controlled multi-layer provisioning of dynamic 100 Gb/s Ethernet services.

SDN Solution Value

Infinera’s SDN solutions are designed to enable step-by-step evolution, with hybrid control of network services and resources using SDN in parallel with Infinera’s existing, proven management systems. This enables operators to smoothly evolve to an SDN environment without disrupting existing customers, services and revenues.

Infinera’s Transport SDN solutions deliver the following key values:

  • Increased Revenues: Through automatic operations and better use of previously underutilized network assets, service providers are able to create new markets and cater to a wide range of customers, resulting in increased revenue opportunities.
  • Customer Retention: Through innovative on-demand services, accelerated speed of service provisioning and delivery, flexible contracts, and most importantly allowing customers to build their own applications that can integrate with the network’s open APIs, service providers can improve customer experience.
  • Reduced CapEx and OpEx: Through automated operations that enable efficient resource allocation and traffic optimization within a multi-layer network, service providers can shorten service delivery times and also reduce both router and transport resources.
