Diamond sketch: Accurate per-flow measurement for real IP streams

Tong Yang, Siang Gao, Zhouyi Sun, Yufei Wang, Yulong Shen, Xiaoming Li

Abstract: Existing sketches often have low memory efficiencies when performing per-flow measurement tasks on skewed IP streams. In this paper, we propose Diamond Sketch, a novel sketch that dynamically assigns an appropriate number of atom sketches to each flow on demand, improving the accuracy considerably while keeping a comparable speed.
