LibreQoS/v0.8/README.md

v0.8 (IPv4 & IPv6) (Stable)

• Released: 2 July 2021

Installation Guide

• 📄 LibreQoS 0.8 Installation and Usage Guide - Proxmox and Ubuntu 20.04 LTS

Features

• Dual stack: client can be shaped by same qdisc for both IPv4 and IPv6

• Up to 1000 clients (IPv4/IPv6)

• Real world asymmetrical throughput: between 2Gbps and 4.5Gbps depending on CPU single thread performance.

• HTB+fq_codel or HTB+cake

• Shape Clients by Access Point / Node capacity

• TC filters split into groups through hashing filters to increase throughput

• Simple client management via csv file

• Simple statistics - table shows top 20 subscribers by packet loss, with APs listed

Limitations

• Qdisc locking problem limits throughput of HTB used in v0.8 (solved in v0.9). Tested up to 4Gbps/500Mbps asymmetrical throughput using Microsoft Ethr with n=500 streams. High quantities of small packets will reduce max throughput in practice.

• Linux tc hash tables can only handle ~4000 rules each. This limits total possible clients to 1000 in v0.8.
