In the last decade, companies and organizations have rapidly been adopting network virtualization (NV) in an effort to take advantage of the flexibility offered by software-based computing and storage resources. With software-defined networking (SDN) and network functions virtualization (NFV) promoting decoupling of the control and forwarding planes, more emphasis has been put on NV as of late. For example, NEC network virtualization was introduced with the announcement of the ProgrammableFlow Networking Suite in 2011.
How Does NEC Network Virtualization Work?
NEC network virtualization comes in the form of the ProgrammableFlow Networking Suite. The award-winning ProgrammableFlow Networking Suite enables complete network virtualization. It provides a comprehensive network virtualization strategy which gives users the ability to simply deploy, control, monitor, and manage multi-tenant campus and data center networks. Using production-ready SDN methods, NEC network virtualization can provide better flexibility, visibility, and efficiency, while reducing costs of operation.
With it, users are able to unify and control remote networks from a central location, enabling the ability to offer easier network management and better end-user access to applications, enhanced collaboration, and increased efficiency of IT resource use. The ProgrammableFlow Networking Suite also offers both physical and virtual switches, including an SDN Controller and applications.
Its design exposes a logical abstraction plane dubbed the Virtual Tenant Network (VTN) framework, providing deployments of a logical plane on top of any underlying physical network topology. Automatically, the VTN architecture can map a logical plane design into underlying physical network functionalities, which are enabled by creating or adapting the flow rules at specific, individual switches that use the OpenFlow protocol. Not only does it mask the intricacy of the underlying physical network, the logical plane definition also gives users better management of network resources. This leads to a decrease in time to redesign network services, and limits errors within the network configuration.
Benefits of NEC Network Virtualization
The ProgrammableFlow Networking Suite offers several advantages to customer, including:
- Ease of use: Centralizes and automates control of the network by removing fragile and complex protocols
- Fast implementation: Offers high resiliency in Layer 2 and Layer 3 multi-path networks, and its distributed virtual routing function gets rid of bottlenecks associated with the traditional design of networks
- Openness: With support for OpenFlow 1.3 and 1.0, ProgrammableFlow was the first company to earn certification from the Open Networking Foundation (ONF)
- Secure: VTN technology can create isolated and secure virtual networks with their own network policy, and limits complexity and trade-offs that are often seen in traditional network security frameworks.
