In the 5G era, ultra-low latency and high throughput are essential. Traditional virtualized networks can’t keep up. Nubestack NFV Solutions use advanced technologies to deliver near bare-metal network performance in the cloud. We integrate high-speed data plane acceleration so your network functions handle demanding traffic with minimal latency and maximum efficiency.

What Is Network Functions Virtualization (NFV)?

NFV replaces proprietary network hardware (routers, firewalls, load balancers) with software running on standard servers. The challenge: eliminating virtualization overhead. By leveraging SR-IOV, DPDK, and OVN, Nubestack enables virtualized network functions (VNFs) to achieve the speed and efficiency required for modern Telco and cloud-native workloads.

Real-World Example: High-Performance Virtual Router

A service provider needs virtual routers for vCPE, each handling gigabit-speed connections. Standard Linux bridges can’t keep up. With Nubestack:

• SR-IOV gives VMs direct access to NICs, slashing I/O latency
• DPDK enables user-space packet processing at millions of packets/sec
• OVN provides scalable, programmable overlays and security Result: Each virtual router delivers line-rate performance, supporting more customers with less hardware and lower latency.

What We Offer

Data Plane Acceleration: Supercharge VNFs with DPDK for user-space packet processing and huge performance gains. Hardware Direct Access: Use SR-IOV to give VMs direct, isolated access to NICs for near-native speed. Advanced Virtual Networking: Deploy scalable, secure overlays with OVN for flexible, automated network management. Telco Cloud Foundations: Build carrier-grade NFV platforms (OpenStack/Kubernetes) for 5G and edge workloads. Performance Tuning: Profile and benchmark to guarantee your NFV meets SLAs for throughput, latency, and jitter.
