Chapter 19: Discovering I/O and Stream Graphs

Within Wireshark, there are numerous tools that help the analyst understand what is happening on the network. In this chapter, we'll first review some of the key elements found in the Statistics menu. So that you are aware of the many choices of built-in reports, we'll cover some general information and ways to assess the data found within a capture. We'll also discover several reports that help assess protocol effectiveness, along with a survey of basic graphs found in the Statistics menu.

We'll then focus on two main ways to visualize traffic, by using input/output (I/O) and Transmission Control Protocol (TCP) stream graphs. We'll explore how to create basic I/O graphs to help visualize network issues such as dropped connections, lost frames, and duplicate acknowledgments (ACKs). We'll then compare the four types of TCP stream graphs and learn how each of the graphs can lend insight into the health of...
