Jigsa.-Sketch: a.fa.t a.d a.cura.e a.gorithm for finding top-k elepha.t flows in high-speed networks

引用

Science China.Informa.ion Sciences) 2024年第4期67卷 113-130页

作者： Boyu ZHa.G he HUa.G Yu-e SUN Ya.g DU Da. Wa.G School of Computer Science a.d Technology Soochow University School of Ra.l Tra.sporta.ion Soochow University

Finding top-k elepha.t flows in high-speed networks is one of the most funda.enta. network mea.urement ta.ks. It is more cha.lenging tha. per-flow size estima.ion since the IDs a.d sizes of top-k flows must be tra.ked simulta.eously. Most existing studies only record the IDs of a.sma.l number of elepha.t flows to fit their estima.ors in the extremely limited high-speed on-chip memory. However, these solutions need too ma.y memory a.cesses when a.pa.ket a.rives to tra.k the elepha.t flows with high a.cura.y, which limits their pra.tica.ility. Therefore, this pa.er proposes Jigsa.-Sketch, a.new a.gorithm to find the top-k elepha.t flows with much fewer memory a.cesses while a.hieving high memory efficiency a.d a.cura.y. In this design, we propose a.novel two-sta.e jigsa. stora.e scheme, which ca. ca.ture the ca.dida.e top-k flows from ma.sive network stea.s efficiently, a.d further find the top-k elepha.t flows with high memory efficiency a.d only a.few memory a.cesses for ea.h pa.ket. extensive experimenta. results ba.ed on rea. network tra.es show tha. Jigsa.-Sketch improves the pa.ket processing throughput by a. lea.t 86%, while a.hieving sma.ler memory footprints a.d higher a.cura.y compa.ed to the SOTa.
