Networking Challenges in the Cloud

In today’s data center and cloud environment, new business demands and new innovations in compute infrastructure have increased the strains on data center networks.

Economies of scale and improvements in governance are driving demand for IT infrastructure that can handle a variety of workloads. Building networks that enable these benefits is a challenge. Current network equipment lacks flexibility and responsiveness to dynamic business demands, making it difficult to provision and even harder to manage the multitenant networks that cloud services require.

ProgrammableFlow: Creating a Cloud-Ready Network

Easy to manage

Complex, inflexible network configurations are a feature belonging to past decades with ProgrammableFlow. ProgrammableFlow centralizes control of the network, eliminates the need for distributed protocols such as Spanning Tree. ProgrammableFlow streamlines data center management through greater levels of automation while driving down operational costs and time to deliver business services.

Enterprise ready & scalable

In an environment where business requirements are constantly changing, planning for capacity has never been harder. ProgrammableFlow makes scaling out of network resources as easy as scaling out virtualized servers. ProgrammableFlow scales from a single rack integrated into an existing network to an entire data center, all managed from a central console.


ProgrammableFlow automatically monitors and intelligently distributes network traffic across multiple paths. Paths are managed according to custom defined policies and continuously updated based on network resources and traffic conditions. Any path between any two devices can be used, enabling more efficient use of network resources and multiplying the available bandwidth within the network.

Open standards

ProgrammableFlow leverages the OpenFlow protocol to create Software-Defined Network (SDN) virtualization, giving NEC customers freedom of choice. By separating network control from switch hardware, organizations can make infrastructure investment decisions independently from the network features they want to support.


With the standard REST API interface network behavior can be programmed or/and information gathered from the controller, making any integration with the open source world simpler. Both XML and JSON formats are supported.

Core technology

Virtual Tenant Network (VTN) allows network slicing and traffic isolation, abstract physical network as vBridge (L2) and vRouter (L3) and hide physical complexity, through which intent interfaces (VTN policies) are supported.

'Network complexity has grown to a point beyond reasonable. ProgrammableFlow provides an automated means of network self-repair, and gives us the single pane of management and control we have long sought.'

ProgrammableFlow Controller: Unique, Network-Level Virtualization

ProgrammableFlow Controller Software brings the benefits of virtualization to high performance switching. Data center can now deploy, control, monitor, and manage multi-tenant network infrastructure all from a central point.

  • Multi-tenant network virtualization: NEC’s Virtual Tenant Network technology enables administrators to build multitenant networks in which virtual machine migration is unfettered, enabling rapid scale-out of new applications, balanced workloads, and higher levels of availability.
  • Reduced network complexity: ProgrammableFlow’s centralized control of the network eliminates the need for distributed protocols such as Spanning Tree, reducing network complexity and unlocking the network capacity unavailable in networks running Spanning Tree.
  • Enhanced Investment Protection: New network services can be added and extended without changing hardware.
