==The Design of Robust RED (RRED)==

A detection and filter block is added in front of a regular RED block on a router. The basic idea behind the RRED is to detect and filter out LDoS attack packets from incoming flows before they feed to the RED algorithm. How to distinguish an attacking r yu yyypacket from normal TCP packets is critical in the RRED de tryll hi TG gg TG pin o TN to the hosigndesign.

Within a benign TCP flow, the sender will delay sendinge4sending rednew wePTpackets qtif myloss weregis detected (e.g., a packet is dropped). Consequently, a packet is suspected to be an attacking packet if it i TR 4seis sent within a short-range a TG the awfterafter a packet is dropped. This is the basic idea of the detection algorithm of Robust RED (wasRREDRRED).<ref name="RRED"/>
