## Features
* Dual stack: client can be shaped by same qdisc for both IPv4 and IPv6
* Up to 1000 clients (IPv4/IPv6)
* Up to 7Gbps throughput with NVIDIA MCX4121A-XCAT, 4Gbps with Intel X710-DA4
* Up to 4Gbps throughput
* HTB + fq_codel
* Shape Clients by Access Point / Node capacity
* Experimental support for CAKE (Common Applications Kept Enhanced)

* Simple client management via csv file
* Simple statistics - table shows top 20 subscribers by packet loss, with APs listed
## Limitations
* Tested up to 7Gbps/500Mbps asymmetrical throughput with NVIDIA MCX4121A-XCAT. Qdisc locking problem will require integrating <a href="https://github.com/netoptimizer/xdp-cpumap-tc">xdp-cpumap-tc</a> or <a href="https://lwn.net/Articles/840244/">HTB offload</a> feature in future verions to increase bandwidth capacity.
* Tested up to 4Gbps/500Mbps asymmetrical throughput with NVIDIA MCX4121A-XCAT. Tested using <a href="https://github.com/microsoft/ethr">Microsoft Ethr</a> with n=500 streams. Throughput is noticably superior with NVIDIA/Mellanox cards vs Intel X710 for some reason. Qdisc locking problem will require integrating <a href="https://github.com/netoptimizer/xdp-cpumap-tc">xdp-cpumap-tc</a> or <a href="https://lwn.net/Articles/840244/">HTB offload</a> feature in future verions to increase bandwidth capacity.
* Linux tc hash tables can only handle ~4000 rules each. This limits total possible clients to 1000 at this time. Eventually we will rework the code to allow for more clients by linking more hash tables.
## Requirements
* Edge and Core routers with MTU 1500 on links between them
