QoE Control for Broadband Networks
Keep your network responsive when it gets busy.
LibreQoS controls congestion at the subscriber, AP, PON, tower, and backhaul — keeping latency low under load while showing operators exactly where customer experience is degrading.

Topology-Aware Shaping
Your network doesn't have one bottleneck.
LibreQoS models the network you actually built. Subscribers get per-flow CAKE fairness while shared capacity at APs, PONs, towers, sites, and backhaul stays under explicit hierarchical control. When one branch is constrained, congestion is contained there instead of degrading everyone upstream.
Topology-Aware Control
Follow load through the runtime tree
See load on every parent and child node, so the congested segment stands out before you open a chart.
Metro Site
88% load
Shared pressure shows up here before subscriber pain spreads outward.
Backhaul
Pressure path
The congested branch stays visible instead of vanishing into a network-wide average.
West / Harbor
Healthy
The congested branch stands apart from stable parents and clients.
Operational Signals
Keep signal history compact and visible
See latency, retransmits, and quality together so changes are obvious before you open a larger chart.

Why Operators Switch
Why operators switch to LibreQoS
Customer-focused operators need precise shaping, real choke-point control, and faster evidence when subscribers feel the network.
Precise shaping, not black-box guesswork
LibreQoS uses explicit queue control and CAKE-backed fairness instead of opaque congestion logic whose behavior is hard to predict under load.
Explore
Shape at the real choke point
Topology-aware enforcement keeps shaping aligned to the AP, site, OLT, backhaul, or shared segment that is congested.
Explore
Move from symptom to subscriber evidence
Operators can go from a network-wide issue into site, circuit, and subscriber-level evidence with RTT, retransmits, QoO, and Insight drill-down.

How It Works
How LibreQoS shapes traffic
LibreQoS uses CAKE to keep busy networks responsive. Instead of letting downloads and streaming bursts crowd out everything else, it helps gaming, voice, and other interactive traffic stay usable under load.
Basic queueing
Without traffic-aware shaping
A basic queue sends packets in the order they arrive. When download bursts fill the line, interactive traffic has to wait, and the network starts to feel sluggish.

What subscribers feel

Calls, gaming, and other interactive traffic feel slower
LibreQoS with CAKE
Traffic stays fairer under load
LibreQoS uses CAKE to keep interactive traffic moving even when the network is busy, so calls, gaming, and web use stay more responsive.

Live Product View
Live end-user visibility, not just summaries
LibreQoS lets operators watch throughput, queue build-up, and RTT change live on an individual circuit, not just in after-the-fact charts.

Solutions
Built for the networks ISPs actually run
LibreQoS is purpose-built for wireless and fiber operators — shaping at real AP, site, OLT, and backhaul choke points with subscriber-level evidence. The same hierarchy runs dense shared-capacity environments, from event venues to vessels.
Operator Proof
Operators run LibreQoS in production
From single-tower WISPs to multi-site networks, operators use LibreQoS to hold the line on busy-hour quality and prove the result.
"We can afford to deploy a box at every step of the network to manage congestion at very little cost."
Louis Elliott
CEO, Streamline Internet
"LibreQoS let subscribers share higher plan speeds fairly and made the service feel much faster during prime time."

Measure It Yourself
Don't take our word for it. Measure the result.
The public Internet Quality Test measures what subscribers feel on a loaded circuit — idle and loaded latency, jitter, packet loss, throughput, and per-application QoO — and grades the connection from A+ to F. Run it on a busy-hour circuit, deploy LibreQoS, then run it again.
