Figure 3
The flowchart shows a vertical pattern arranged from top to bottom with sequential process boxes, a decision diamond, and directional arrows. At the top, an oval labeled “Start” connects by a downward arrow to a rounded rectangle labeled “1- Establish S D N Virtual Environment”. A downward arrow leads to another rounded rectangle labeled “2- Install Mininet and Ryu controller”, followed by a downward arrow to “3- Build S D N network”. A downward arrow then connects to “4- Ingest the C I C-D D o S 2029 p cap files”. From this box, a downward arrow leads to “5- Capture OpenFlow statistics”. Below, a diamond-shaped decision box reads “All p c p p files ingested”. From this diamond, a rightward arrow labeled “NO” loops back upward and leftward to the box “4- Ingest the C I C-D D o S 2029 p cap files”, forming a feedback loop. From the same decision diamond, a downward arrow labeled “YES” leads to a slanted parallelogram labeled “6- Parse the captured traffic statistics”. A downward arrow connects to a rounded rectangle labeled “7- Save the extracted features in C S V file”. Finally, a downward arrow leads to an oval labeled “END”.Proposed SDN-DDoS2025 generation flowchart. Source: Created by the authors
