A Paradigm Shift in 5G Deployment: The Promise of eBPF for Open...
summary
Demonstrates eBPF applied to a Kubernetes 5G core using Cilium operator, Ur Sim and open 5DS and compares VM+iptables vs pod-based eBPF networking; measures CPU, memory and network KPIs and runs end-to-end UE registration, PDU sessions and subscriber ops. Results show 48% CPU reduction (47% → 24%), memory 29% → 18.9%, and latency down from 2.8 ms to 2.2 ms (~20%) in a live demo with 100 UEs, with iptables removed and context-switch overheads reduced.
