It's simple and it perfectly meets my needs. It's called wondershaper . It's a very simple CBQ (or HTB) based queueing discipline script that allows you to throttle bandwidth while alotting some simple priorities. I've used it to shape the "bulk" services hosted on my cable modem to a fraction of the modems bandwidth. I prioritize dns, pop, smtp, imap, and http as bulk classes. So now my DC games won't be spiked by a largely attached porn spam or somebody hitting my website. Since I had to reboot because of the kernel compile I installed the extra 256MB RAM I've had for a year now. Lost uptimes...
