LibreQoS is an open source Quality of Experience (QoE) platform that helps Internet Service Providers (ISPs) enhance their customers’ internet connections. It leverages state of the art Flow Queueing (FQ) and Active Queue Management (AQM) algorithms to manage latency and bufferbloat over existing infrastructure. It also monitors performance by measuring end-to-end TCP round trip time for each subscriber, Access Point, and Site on a network. LibreQoS ensures fair allocation of bandwidth, prioritizes critical real-time applications, and promotes connection quality, equity and access.
LibreQoS runs on a server acting as a managed bridge 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
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.
LibreQoS and Your Network
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.
