I testet a lot with queues and with burst with long bursttime. But that doesn't work!
It is coded in v3.2 and seem to work. I'm a newbie in MT scripting so there maybe better ways to code ..
To the script in short sentences..
- it can limit the amount of traffic in specific period of time
- it can slowdown the speed slowly if user comes to the given amount of traffic
- need no usermanager
- can remember the traffic after reboot, (trafficinfo stored in queuename, maybe there is a better way.. please tell me when)
- speed of queues can adjust from every minute to unlimited (need scheduler)
- adjust only specific queues (names of queues must start with a special string you can choose)
- many parameters to adjust for your needs
- many comments i hope you understand it..
please..
- test it
- tell me bugs
- lets improve it
- tell me what you think about ..
