Flow Graphs are best used to visualize which aspect?

• A. Draft packet contents
• B. Number of packets per second
• C. Relationships among network flows
• D. Protocol hierarchy levels

Answer: (C)

Flow graphs focus on how different network flows relate to one another and interact across the network. They map flows as entities and show the connections and dependencies between them—such as sharing the same link, competing for bandwidth, causing contention in a queue, or affecting each other’s performance. This view helps you see how multiple flows influence each other, spot bottlenecks, and reason about traffic engineering or QoS decisions. Draft packet contents aren’t what a flow graph emphasizes because those graphs don’t depict payload details; they’re about relationships between flows, not the actual data inside packets. Visualizing the number of packets per second would highlight rate or volume, not how flows are connected or interfere. Protocol hierarchy levels relate to layering in the stack, which is a different kind of structural view than how flows interact across the network.
