NFWare Virtual Load Balancer

L3–L7 Load Balancing for Modern Networks. Optimised for performance. Designed for reliability. Built to scale.

Virtual Load Balancing solution

It empowers operators, service providers, and enterprises to deliver exceptional user experiences while maintaining full control over performance, reliability, and security — even under the most demanding traffic conditions.
In a digital-first world, ensuring application availability, performance, and scalability is critical to success. NFWare ADC is purpose-built to deliver high availability, ultra-fast response times, and seamless scalability across modern network environments.

NFWare ADC benefits

High Performance
NFWare Load Balancer is engineered for exceptional speed. Leveraging cutting-edge technology, it guarantees lightning-fast traffic distribution and processing.
Scalability
One of the standout features of NFWare ADC is its effortless scalability. Whether your network needs to accommodate increased user demand or the addition of new servers...
Cost-Effective
NFWare ADC runs on stardard x86 servers, doesn’t require expensive specialized hardware. It optimizes resource utilization and allowingto make the most of their existing hardware.
NFWare ADC is built for high-performance environments, ensuring fast, efficient traffic distribution across Layers 3 to 7. Its virtualised, software-based design allows seamless scaling based on real throughput needs — with consistently low latency, even under heavy load.

Running on standard x86 servers or in the cloud, it eliminates the need for specialised hardware, reducing both CAPEX and OPEX. Thanks to its efficient resource usage and easy deployment, NFWare ADC offers a much lower total cost of ownership, making it a smart, scalable choice for service providers and enterprises.

Designed for every layer to support various use cases

Consistent hash
Load Balancing on a routing level
IP
L3
Does not terminate TCP
Symmetric mode or DSR mode
Designed for high performance
TCP / UDP
L4
HTTP(S) 1.0/ 1.1
L7
Terminate TCP
Feature-rich
Operates with data flows
With built-in Global Server Load Balancing (GSLB), it keeps services available and responsive across geographically distributed networks.
NFWare ADC operates across Layers 3, 4, and 7, providing intelligent load balancing at every layer — from efficient IP distribution to sophisticated application-level routing.
