notes about bandwidth monitoring and quotas
The goal is to find a way to cap bandwidth usage, in and out. The system can apportion the shareable bandwidth to a percentage of total bandwidth available. Here we research how this can be done.
tc − show / manipulate traffic control settings
Tc is used to configure Traffic Control in the Linux kernel.
- man page for tc: http://man.cx/tc

QOS
Quality of Service (qos-scripts) configuration
Once we have the monitoring in hand we can then handle the bandwidth caps. We might want to cut off access once the limit has been reached.
monitoring
to track bandwidth we need a way to quantify it. Here are some likely candidates:
- bandwidthd - very popular, but apparently it is resource heavy
- bmon - download it
- iftop, man page - "iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts."
ubus
OpenWrt micro bus architecture - there is a Lua module for ubus...
