Which graph type would best illustrate the relationships between distinct network flows?

• A. Summary of Captured Packets
• B. IO Graphs
• C. Protocol Hierarchy Statistics
• D. Flow Graphs

Answer: (D)

To visualize how distinct network flows relate to one another, flow graphs are the most effective. In a flow graph, each node represents a single flow defined by attributes like source, destination, protocol, and ports. Edges between nodes encode relationships such as sharing a source or destination, participating in the same session, or occurring in a sequence, helping you see clustering, dependencies, or anomalous chaining across flows. This makes it possible to spot patterns such as a single host initiating many flows to multiple destinations, or a set of flows that follow one another in quick succession, which might indicate coordinated activity. The other visualizations focus on different aspects: a summary of captured packets gives counts and basic metadata rather than connections; protocol hierarchy statistics show how traffic is distributed among protocols but not how flows relate; IO graphs display throughput or packet rate over time, which highlights timing and volume rather than inter-flow relationships. Therefore, flow graphs best illustrate the relationships between distinct network flows.
