Token Bucket Filter The Token Bucket Filter (TBF) is a simple qdisc that only passes packets arriving at a rate which is not exceeding some administratively set rate, but with the possibility to allow short bursts in excess of this rate. TBF is very precise, network- and processor friendly. It should be your first choice if you simply want to slow an interface down! 9.2.2.2. Sample configuration A simple but *very* useful configuration is this: # tc qdisc add dev ppp0 root tbf rate 220kbit latency 50ms burst 1540 Ok, why is this useful? If you have a networking device with a large queue, like a DSL modem or a cable modem, and you talk to it over a fast device, like over an ethernet interface, you will find that uploading absolutely destroys interactivity. This is because uploading will fill the queue in the modem, which is probably *huge* because this helps actually achieving good data throughput uploading. But this is not what you want, you want to have the queue not too big so interactivity remains and you can still do other stuff while sending data. The line above slows down sending to a rate that does not lead to a queue in the modem - the queue will be in Linux, where we can control it to a limited size. Change 220kbit to your uplink's *actual* speed, minus a few percent. If you have a really fast modem, raise 'burst' a bit. -- Greets, fr33zb1 A mail-list of Linux Users Group - Bulgaria (bulgarian linuxers). http://www.linux-bulgaria.org - Hosted by Internet Group Ltd. - Stara Zagora To unsubscribe: http://www.linux-bulgaria.org/public/mail_list.html
