Traffic Shaping over Satellite Internet | |

I've set up Traffic Shaping on a Linux Router. Using HTB with SFQ, i'm trying to slow down heavy downloading for 20 subscribers over a 2048 kbit downlink. I'm classifying internet related traffic using iptables marking. bri0 is my local lan bridge, receiving egress traffic destined for subscribers. tc qdisc add dev bri0 root handle 1: htb default 2 tc class add dev bri0 parent 1: classid 1:1 htb rate 92129kbit ceil 102400kbit tc class add dev bri0 parent 1:1 classid 1:2 htb rate 90072kbit ceil 92129kbit tc class add dev bri0 parent 1:1 classid 1:3 htb rate 2048kbit ceil 92129kbit # Non-Internet Local Lan Traffic tc qdisc add dev bri0 parent 1:2 handle 2: sfq perturb 10 # Internet Traffic tc class add dev bri0 parent 1:3 classid 1:9 htb rate 50kbit ceil 100kbit # Unknown Internet Traffic tc qdisc add dev bri0 parent 1:9 handle 9: sfq perturb 10 # Known Subscribers, based on IP Address, ea. subscriber gets their own class, # starting with 1:10 (a script populates the classes for me) tc class add dev bri0 parent 1:3 classid 1:(10->X) htb rate 100kbit ceil 400kbit tc qdisc add dev bri0 parent 1:(10->X) handle (10->X): sfq perturb 10 Then the classifier: # Send Internet traffic, marked 3, to Class 1:3 tc filter add dev bri0 protocol ip parent 1: prio 1 handle 3 fw flowid 1:3 # Send traffic, based on dest. IP to their corresponding classes tc filter add dev bri0 protocol ip parent 1: prio 1 u32 match ip dst 10.200.0.(2->X)/32 flowid 1:((2->X) + 10) Does this look like a good solution? Can this really slow down heavy downloads, so all subscribers can at least get ..some.. traffic? Does traffic shaping, not policing, also drop packets when a HTB class exceeds it's rate, or does it just wait until there are enough tokens? Thank you for any guidance..
