Real-Time Insight in the Virtualized Environment

Industry research firm 451 Group predicts that the network functions virtualization (NFV) market will reach approximately $3.1bn in 2017. This rapid movement has created challenges in the deployment of software-defined networking (SDN) and NFV, including the need for effective network management while ensuring performance at high speeds. Napatech's recent whitepaper, "Time to ReThink SDN and NFV Performance," argues that virtualization-aware appliances have the ability to solve many of the challenges in these environments.

Analysis acceleration is a critical component in network appliance performance, as it provides guaranteed data capture and delivery at speeds up to 100 Gbps. Napatech has identified solutions to assist network managers to achieve this in the SDN/NFV environment.

  • Ensuring high performance levels: Performance and the ability to assure reliable, real-time data for management and analytics are already a concern today and will be no less of a concern when virtualizing the network.
  • SDN/NFV require a mixture of existing and new solutions: It is broadly accepted that there are certain high-performance functions in the network that will be difficult to virtualize at this time without resulting in performance degradation.
  • Virtualization-aware appliances provide the solution: One way of addressing this issue is to consider the use of physical appliances to monitor and secure virtual networks. Virtualization-aware network appliances can be "service-chained" with virtual clients as part of the service definition. These physical appliances monitor and secure virtual networks and provide the insight to enable event-driven automation of policy decisions and real-time reaction to those events, thereby allowing SDN controllers and NFV management to administer and secure networks.
  • Napatech accelerators enable flexible, scalable network applications:
    • Products range from 1 to 100 Gbps, enabling understanding and acceleration of real-time data for full visibility of all network traffic. This is done through capacity, intelligence, precision and control.
    • By using Napatech accelerators in commercial off-the-shelf servers, network equipment manufacturers can build appliances that provide intelligent analysis, regardless of the environment.

"Virtualization-aware appliances truly provide the bridge between the networks of today and the software-based models of the future. The real-time insight provided by virtualization-aware appliances using analysis acceleration allows the full agility and flexibility of SDN and NFV to unfold. Napatech accelerators allow our customers to stay ahead of the data growth curve, while reducing time-to-market and risk." -- Peter Ekner, VP of product management, Napatech
