Case Study: Leading Telecommunication Operating and Internet Service Providing Company achieves 6x DNS resolving capacity with Radware's Alteon 5412

Leading Telecommunication Operating and Internet Service Providing Company - Customer Case Study

A leading Tier‑1 European telecommunications operator and ISP with more than 150,000 employees and over 100 million subscribers faced rapidly growing Internet traffic that threatened DNS capacity and service continuity across its multiple data centers. The operator needed a high‑performance load‑balancing solution that could handle 1M DNS queries per second per data center while preserving existing hardware, staff expertise and investment.

The operator deployed 18 Radware Alteon 5412 Application Switches across four data centers to load‑balance DNS servers and firewalls; each unit exceeded the 1M DNS QPS requirement. The rollout increased DNS resolving capacity sixfold (from 700K to 4M QPS), provided 10GE connectivity with flexible throughput licensing, delivered carrier‑grade high‑availability, reduced OPEX by upgrading from Alteon 3408 units, and secured a 5‑year platform longevity guarantee for lower TCO and future growth.
