This is one of my test classes: class htb 1:10 parent 1:1 prio 0 quantum 2048 rate 160Kbit ceil 400Kbit burst 1803b/8 mpu 0b cburst 2111b/8 mpu 0b level 0 Q1: where does "level 0" stand for? Q2: where does this b/8 stand for? Q3: this is on a i386 platform, so timer resolution should be 10mS. According to the doc the minimal burst should be 10mS*160Kbit=1600. Why is it 1803? Q4: I want this class to be able to allow 400Kbit burst during 3 seconds. What value should I give to the burst parameter? Is this 400/160*1803=4507b? TIA, Richard. _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
