Jim Gettys providesan extensive look at the FQ_CoDel queue-management algorithm as a bigpiece of the solution to bufferbloat problems. "Simple'request/response' or time based protocols are preferentially scheduledrelative to bulk data transport. This means that your VOIP packets, yourTCP handshakes, cryptographic associations, your button press in your game,your DHCP or other basic network protocols all get preferential servicewithout the complexity of extensive packet classification, even under veryheavy load of other ongoing flows. Your phone call can work well despitelarge downloads or video use."
