European Patent Granted for Groundbreaking DNS-Based Client-side Load Balancing Innovation

Osijek, Croatia – June 4, 2025 – The European Patent Office (EPO) has officially granted a pioneering patent to Croatian tech firm DynConD Ltd., marking a major milestone in cloud infrastructure technology and DNS innovation.

The patent, filed under application number EP22750887, introduces a novel method of transferring all client-side global server load balancing (GSLB) data exclusively through DNS TXT records. Officially published under patent number EP4364389, this breakthrough is set to transform how internet traffic is routed in multi-cloud and high-availability environments.

 About the Invention

Titled “Method of Using Only TXT Domain Name System Resource Records to Transfer All Data Used by Client-Side Global Server Load Balancers and Its Implementation”, the patent protects a method that enables fully client-side load balancing decisions using only DNS infrastructure.

This approach allows client devices to make smart routing decisions in real-time, based on pre-defined logic encoded directly within DNS TXT responses. It reduces latency, improves fault tolerance, and enhances security — all without relying on centralized server-side global server load balancers.

Why It Matters

In an era of multi-cloud adoption, data localization mandates, and growing pressure to comply with NIS2 and GDPR, DynConD’s innovation offers a decentralized, lightweight, and regulation-friendly solution to global traffic management.

This patent represents not just a technical achievement, but a shift in how we think about availability, sovereignty, and control in internet infrastructure.

 A Strategic Asset

The granted patent gives DynConD a significant edge in the competitive GSLB infrastructure market. The method supports a wide range of applications, including:

• Smart multi-cloud orchestration
• Cost-optimized routing between premium and budget cloud providers
• Decentralized load balancing service without a SPOF
• High availability for network services
• GDPR, NIS2 and DORA compliance for companies

With this protected intellectual property, DynConD now stands as the only company worldwide offering client-side GSLB as a fully patented, commercial-ready service.

 What’s Next?

DynConD currently has another patent pending for Energy Efficient use of server resources and server load management using a client side GSLB. The company plans to actively pursue licensing and partnership opportunities, especially with global CDNs, cloud providers, and telecommunications operators. The grant of this patent further strengthens DynConD’s value proposition as it continues to expand into EU and international markets.
