Case Study: National Instruments

Ramping up network performance while slashing costs

National Instruments' bandwidth requirements were growing by 10-25 percent every year, but its IT budget wasn't keeping up. Part of the company's problem was that most sites had different requirements. National Instruments wanted to improve its global network's capacity and performance, without taking on huge costs. Cisco SD-WAN, designed and implemented by Cisco Services, brought global users 30 times the bandwidth at one-third the price.



  • Increased bandwidth and security burden on National Instruments' WAN impacted sales, R&D, manufacturing, and contact centers at 88 global sites.
  • Teams competed for bandwidth, with demand growing at an annual rate of 10-25 percent.
  • Needed to improve global network capacity and performance, without taking on huge costs.


  • Software-defined networking intelligence and centralized policy control optimized traffic and performance across the WAN.
  • Traffic was distributed over lower-cost Internet connections instead of expensive MPLS links. MPLS bandwidth costs were reduced by an average of 64 percent per site.
  • WAN bottlenecks no longer impacted the business bottom line.

What they're saying

With Cisco SD-WAN, we've reduced our MPLS spending by 25 percent and increased bandwidth by 3,075 percent.
