LibreQoS
LibreQoS is a Quality of Experience (QoE) open source platform that leverages state of the art (and IETF standardized) Flow Queueing (FQ) and Active Queue Management (AQM) algorithms to help Internet Service Providers (ISPs) enhance their customers’ internet connections. It effectively manages latency and bufferbloat over existing infrastructure. LibreQoS ensures fair sharing of bandwidth, prioritizes critical real-time applications and promotes connection quality, equity and access.
LibreQoS runs on a server acting as a middlebox between an ISP’s edge router and the core of the network. Servers running LibreQoS can shape traffic for many thousands of customers.
The Importance of Low-Latency Connectivity
Employment
Keep remote workers productive and employed
Education
Keep students engaged and on-track with their peers
Equity
Reduce educational and employment inequities
Health
Ensure reliable access to tele-medicine
LibreQoS can improve the reliability of end-users’ voice and video calls transiting the network. With work-from-home, remote learning, and tele-medicine becoming increasingly common – it is important to minimize any disruptions to video calls and VoIP that might otherwise occur due to bufferbloat within the ISP network.
Adoption Worldwide

LibreQoS and Your Network
Happy Customers
Ensure the most latency-sensitive end-users (gamers, remote workers, remote learners) have a great experience
Performance
Control congestion at every point in your network fabric - and deliver performance that sets you apart from the competition
Reduce Churn
Alleviate the most common pain points for customers who stream video, play video games, and video conference.
LibreQoS allows operators to mitigate latency under load (bufferbloat) at every possible congestion point in the network fabric – providing a smooth, stable end-user experience that can help ISPs maintain existing customers as well as attract customers. Many of us take it for granted that it is “normal” for an end-user’s video call to stutter or disconnect when someone else on the same home network is watching a 4K video. That is actually a symptom of bufferbloat, and can be mitigated with LibreQoS. LibreQoS ensures the most latency-sensitive end-users (gamers, work-from-home clients, remote learners) have a positive experience, which in turn increases customer retention and reduces ISP costs related to support tickets, calls, and truck-rolls.

Equinix

Equinix supports LibreQoS through its Open Source program – providing access to hardware resources on its Equinix Metal infrastructure. Equinix’ support has been crucial for LibreQoS to scale past 10Gbps for higher-bandwidth networks. Learn more about Equinix Metal here.
NLNet

LibreQoS has been funded through the NGI0 Entrust Fund, a fund established by NLnet with financial support from the European Commission’s Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 101069594.
