QoE Control for Broadband Networks01 / LIBREQOS

Less congestion. More retention.

Keep subscriber connections responsive under load with intelligent, topology-aware traffic shaping.

02 / 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.

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.

Deterministic queue control 02

Shape at the real choke point

Topology-aware enforcement keeps shaping aligned to the AP, site, OLT, backhaul, or shared segment that is congested.

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.

Subscriber-level proof faster

03 / 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.

Wireless ISP

Reduce peak-hour complaints and keep shaping aligned to real AP, site, and backhaul bottlenecks.

Backhaul-aware shaping

Fiber ISP

Give support teams stronger evidence about congestion, upstream trouble, and subscriber-side issues.

Subscriber evidence faster

Managed WiFi Operators

Give managed-service teams a repeatable way to allocate shared capacity, compare locations, and investigate guest complaints across events, venues, hotels, vessels, and aircraft.

Operator Proof

“We can afford to deploy a box at every step of the network to manage congestion at very little cost.”

Operator Proof

“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.

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.
