e-DN: eBPF-Defined Network

Transforming Telecom Infrastructure from Brownfield to Cloud-Native Greenfield

Solution Overview

Cloud-native eBPF-powered telecom infrastructure

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.
