Cybersecurity (Security+) and P4 Programmable Switches Lab 9: Identifying Heavy Hitters using Count-min Sketches (CMS) Elie Kfoury, Jorge Crichigno University of South Carolina http://ce.sc.edu/cyberinfra Western Academy Support and Training Center (WASTC) University of South Carolina (USC) Energy Sciences Network (ESnet) June 23rd, 2023 1
Topology and Lab Objectives The topology consists of a P4 switch and four hosts Objectives: Write a P4 program that implements a CMS Multiple short flows from h1 to h2 using wget A heavy hitter flow from host h3 to h4 using iPerf3 The P4 switch detects the flow and blocks the traffic Short flows (web traffic) Heavy hitter (iPerf3 flow) 3
