NEC Nets SI Corporation adopts Colt network solutions into its backbone network

NEC Nets SI Corporation

NEC Nets SI’s network systems exist to connect people, businesses and society seamlessly, combining self-constructed infrastructure coupled with strong customer support. NEC Nets SI’s total system solutions provide communications systems and high-speed networks, along with measures to ensure safety and security, and run energy-saving, eco-friendly facilities. All of this contributes to creating an optimized environment to support customers’ business growth.

NEC Nets SI Corporation’s business challenge

NEC needed to furnish a system that would enable end users to both reduce costs and provide more optimized performance. They also wanted to avoid sacrificing quality or stability, and at the same time avoid any drastic changes to their current connectivity environment. Finally, end users needed the ability to connect in conformity with the same WAN environment used by the larger group entities.

Why Colt

Colt was selected on the basis of

  1. low pricing
  2. a wealth of experience in providing low- latency networks, and
  3. backbone network stability coupled with redundancy protection. Colt also provides a single point of contact for operations, further reducing customer burden.

Future plans

NEC Nets SI plans to replace sections in its metropolitan connectivity area with Colt circuits to reduce cost further, improve latency and maintain stability.

With Colt, we can offer premium quality (low latency) with outstanding value for money, as well as network diversity to our end users. By incorporating a 1Gbps network in the core of the end-user backbone network, we can reduce workloads and achieve necessary operational stabilityTatsuya Hayashida, System Manager, Cloud Implementation, New Solution Promotion Division, NEC Nets SI Corporation
