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 âˆ’ show / manipulate traffic control settings
Tc is used to configure Traffic Control in the Linux kernel.
- man page for tc: http://man.cx/tc
- Ixgr's setup using tc to fix bufferfloat: http://blog.lxgr.net/posts/2013/01/28/my-openwrt-setup/
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."
