Not quite, no. The dropping of packets is based on actual calculations in RED that aren't available in SFQ. SFQ drops _all_ the packets off the end and doesn't start doing so before congestion happens -- RED is designed to drop packets before getting overly congested so that the stream speeds stay steady and don't try to climb above what's available. -- Michael T.
