ISP-Grade GPON Network: Full Infrastructure Stack

Multi-VLAN dual-stack ISP network on physical MikroTik, Cisco and Huawei GPON hardware, with a virtualized service stack and unified observability.

The project

An ISP-grade network on real hardware: MikroTik routing, Cisco switching and a Huawei OLT/ONT GPON plant, with multi-VLAN segmentation and dual-stack IPv4/IPv6 end to end.

Services run virtualized on Ubuntu Server: BIND9 DNS, Kea DHCP, Postfix and Dovecot email, a Caddy reverse proxy with load balancing, and LibreQoS for per-client bandwidth. Prometheus, Grafana and LibreNMS monitor every physical and virtual device over SNMP.
