Solve Customer Dissatisfaction
Solve issues before they impact customers - Take a proactive approach with the industry-leading QoE solution.
Analyze Your Network In Real Time
LibreQoS provides a real-time view of your network. With live monitoring of TCP Round Trip Time, TCP Retransmits, and Throughput – LibreQoS allows you to see exactly where data is flowing on your network, and to identify any potential customer pain-points that may exist.
Instant Assessment
LibreQoS enables a comprehensive, live mapping of your network. Below is the LibreQoS Tree Overview. This view allows you to quickly spot which Nodes (Sites, APs, etc) are experiencing good or poor QoE on your network. Bands between nodes change color based on utilization, with red meaning high utilization. The rectangles for each node are color-coded based on TCP Round Trip Time – with red indicating high RTT, and potential customer QoE impact.
Simple, Automatic Network QoE Optimization
Trusted by 600+ Networks Worldwide

Features
Advanced Network Monitoring
LibreQoS monitors key QoE metrics such as TCP Round Trip Time (RTT), TCP Packet Retransmissions, Flows, Throughput, and Utilization. These metrics are recorded per subscriber, access point, OLT, site, tower, and backhaul - all using passive monitoring techniques (no SNMP needed).

Traffic Shaping Based On Network Topology
LibreQoS allows Network Operators to apply traffic shaping based on the capacities of each bottleneck in the access network. LibreQoS uses hierarchical shaping to ensure that throughput at any choke-point along the network (back-hauls, access points / OLTs) will not exceed the equipment's actual capacity. LibreQoS’ network topology based shaping helps mitigate harmful micro-bursts of traffic – ensuring smooth, stable connectivity for all users. It also allows network operators to support more users on the same network infrastructure than would be possible using competing QoE solutions.

LibreQoS Tree Overview
Flow Queuing with CAKE
LibreQoS uses CAKE (Common Applications Kept Enhanced) - a modern Active Queue Management (AQM) technique. CAKE is based on the highly popular AQM fq_codel - and is the product of nearly a decade of development efforts to improve on its foundations. CAKE ensures that a subscribers' "bulk" flows will not harm their "active" flows. For example, if a subscriber is on an important Zoom call, and a computer's OS downloads a large update in the background, CAKE ensures that the subscriber's Zoom call receives priority in the packet queue. CAKE is highly effective at ensuring smooth, stable video conference calling, Voice over IP, and real-time online applications such as online multiplayer gaming.
