Distributed BNG Architecture Using eBPF/XDP for ISP Edge Infrastructure

A five-star bake. Worth schmearing, sharing, saving.
Summary
The article presents an innovative approach to ISP infrastructure by developing an open-source, eBPF-accelerated Broadband Network Gateway (BNG) that runs directly on Optical Line Terminal (OLT) hardware. The author explains how traditional centralized BNG appliances create bottlenecks and single points of failure in ISP networks, and proposes a distributed architecture using eBPF/XDP technology to eliminate expensive proprietary appliances. The solution aims to revolutionize ISP edge infrastructure by moving BNG functionality to the network edge, improving performance, reducing costs, and increasing reliability.

Traditional ISP architecture looks like this: Customer → ONT → OLT → [BNG Appliance] → Internet
Centralised BNG is a Bottleneck
