![]() ![]() The graph's direction is in the upper part of the window. Click Statistics, TCP Stream Graphs, and TCP Graph (Stevens).Ī new window opens with the Stevens TCP graph. Next, open one of the TCP diagrams and plot the connection. Selecting any packet in the packet list is sufficient. To open a graph, you must select a packet belonging** to the relevant connection in the packet list. ![]() ![]() TCP Graphs BasicsĪll TCP graphs, whether Stevens or the trace flavor, represent one TCP connection in one direction. In this PacketSafari article, we will start from the basics, work our way to more advanced concepts, and provide clear patterns to look for when troubleshooting a TCP connection. There are two versions of the time sequence graph, the more straightforward Stevens graph** and the more advanced TCP trace graph. This article will teach you how to interpret TCP connections using the TCP time-sequence graphs. Wireshark offers a couple of graphs for TCP analysis: RTT, throughput, window scaling, and the time sequence graphs. Having a basic understanding of how Wireshark visualizes packet information in a TCP graph, you can take shortcuts in the analysis workflow and avoid spending many hours looking for patterns that are barely visible in the limited perspective of the packet list. Why don't you use graphs instead? They are a powerful tool in a packet analyst's craft. ![]()
