e-DN: eBPF-Defined Network

Transforming Telecom Infrastructure from Brownfield to Cloud-Native Greenfield

Solution Overview

e-DN is a comprehensive framework for cloud-native telecommunications infrastructure, leveraging eBPF (extended Berkeley Packet Filter) technology to transform legacy brownfield deployments into modern greenfield networks. By enabling in-kernel programmability, e-DN delivers high-performance packet processing, advanced observability, and dynamic network control without requiring hardware replacement or service disruption.

In-Kernel Programmability

eBPF programs run directly in the Linux kernel for maximum performance and security

Cloud-Native Design

Built for Kubernetes environments with containerized deployment and orchestration

High Performance

XDP enables line-rate packet processing with sub-microsecond latency

Deep Observability

Real-time network telemetry and tracing for comprehensive visibility

Gradual Migration

Phased transition from legacy infrastructure without service interruption

Production Ready

Proven in enterprise deployments with comprehensive testing and validation
