DShaper

If you're looking for a variable bandwidth traffic shaper, DShaper might be exactly what you're looking for. This software can be configured to adjust the size of a DUMMYNET pipe based on the volume of traffic flowing through that pipe. And if you're looking to further customize your experience, DShaper even offers two additional features: autonegote and snmpstat.

Autonegote is a discipline function that can adjust your DShaper ruleset based on actual pipe usage. This feature gives you even more control over your network traffic and can help ensure that your pipes are never overloaded. On the other hand, snmpstat enables DShaper statistics to be exported via snmpd. This can be extremely useful if you're monitoring pipe traffic using an snmp application like cacti or mrtg.

And while there are currently no plans to add any additional features to DShaper, the software is still incredibly useful in its current state. The latest release includes a number of minor updates that make it easier to use and more effective. The code has been restructured and cleaned up, and there's even support for features like minbw, maxbw, burst, pointpercent, and minempty. And if you're using FreeBSD 4.11, you're in luck – DShaper has been extensively tested on this platform.

So, if you're looking for a traffic shaper that offers all the features you need to safeguard your network, look no further than DShaper. Please note that the developer is currently reviewing license options and should have the source code available shortly. The software is currently leaning toward the BSD license, so be sure to read the license file before using the current binary release.
