* TC filters divided into groups with hashing filters to significantly increase efficiency and minimize resource use
* VM running LibreQoS with 1000 client rules uses just 250MB RAM on average
* Simple client management through csv file
* Simple statistics - table shows top 20 subscribers by packet loss, with APs listed
## Limitations
* Linux tc hash tables can only handle ~4000 rules each. This limits total possible clients to 2000 single-protocol clients (IPv4 only / IPv6 only) or 1000 dual stack clients. Eventually we will rework the code to allow for more clients by linking to hash tables.

## Requirements
* Edge and Core routers with MTU 1500 on links between them
* If you use MPLS, you would terminate MPLS traffic at the core router. LibreQoS cannot decapsulate MPLS on its own.

* Network interface NIC supporting two virtual interfaces for traffic shaping (in/out), preferably SFP+ capable
* <a href="https://www.fs.com/products/75600.html">Intel X710</a> recommended for anything over 1Gbps.
* Python 3
* python3 -m pip install ipaddress schedule
* python3 -m pip install ipaddress schedule prettytable
* If running as service:
* sudo python3 -m pip install ipaddress schedule
* sudo python3 -m pip install ipaddress schedule prettytable
* Recent Linux kernel for up-to-date linux tc package. Ubuntu Server 20.04.1+ recommended
