NEC scales OpenFlow SDNs

By , Network World |  Networking, NEC, OpenFlow

SANTA CLARA -- NEC this week rolled out a new version of its SDN software that includes an OpenFlow-based method for interconnecting data centers.

Call ProgrammableFlow Networking Suite 5.1, the software includes a capability called Unified Network Coordinator, which is designed to enable construction and orchestration of virtual networks across multiple controllers within a data center as well as across interconnects between data centers. In so doing, UNC addresses requirements for improved disaster recovery and business continuity, greater bandwidth for new applications, big data and maintaining service levels, better access to remote applications and data, reduced management complexity and increased security.

The application is similar to what Google is doing with OpenFlow to interconnect data centers over a WAN.

UNC also enables moving virtualized resources to and from dispersed geographic locations, either because of expansion or consolidation. It also allows customers to collaborate on planned or unplanned events, such as weather-related outages or emergencies, NEC says.

Customers can also gain end-to-end policy across multiple SDN controllers and domains with UNC's data center interconnect capabilities, NEC says.

Each UNC controls up to 10 controllers or 10 sites, or 10 zones in a large data center; 2,000 switches; 30,000 Virtual Tenant Networks (VTN);  100,000 VLANs; and 10 million flows, NEC says.

NEC will be demonstrating ProgrammableFlow Networking Suite 5.1 at this week's Open Networking Summit 2014 conference. The software will be available in April at no charge to existing customers.

NEC first launched its ProgrammableFlow Networking Suite in 2011 as an OpenFlow-based SDN and network virtualization application for multi-tenant networks.
