Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions.
You will pick several iperf3 servers (at least 3, ideally located in separate geolocations), and plot bandwidth vs. the RTT to the servers. You can use ping to get the RTT. Script. Bash/shell script you use to connect and ping the servers. It should at least contain the specific iperf and ping commands you run. Questions: You may also find useful these materials for Wireshark Labs (see the bottom table on the page). Project 1: Writing Wireshark filter expressions for packet capture Project 2: Using ping for RTT distribution and tracert for route discovery Project 3: Analysis of RTP and RTCP Packets Project 4: Analysis of RTP packet delay and loss The RTT estimate we just got from the handshake gives us an estimate of the length of this network path. A measurement of how many packets we can fit in this pipe is the Pipe Capacity or the Bandwidth Delay Product - PC [bits] = R [bits/s] * RTT [s], where R is the smallest bandwidth. Pipe Capacity is then a measurement of volume. Note: Wireshark has a nice feature that allows you to plot the RTT for each of the TCP segments sent. Select a TCP segment in the “listing of captured packets” window that is being sent from the client to the gaia.cs.umass.edu server. Then select: Statistics->TCP Stream Graph->Round Trip Time Graph. 8.

Wireshark is the world's leading network traffic analyzer, and an essential tool for any security professional or systems administrator. This free software lets you analyze network traffic in real Wireshark is a network protocol analyzer, and is the standard in many industries. It is the continuation of a project that started in 1998. Hundreds of developers around the world have contributed
RTT, or round-trip time, is the time that it takes to send a message and receive the result from server. As I searched this, this seems to be the same as ping in network jargon. Are there some important differences between the two concepts/terms or ping can be considered as RTT?
Capture filters with protocol header values. We can create capture filters by making use of offset values within protocol header fields. The syntax used is proto[offset:size(optional)]=value, where proto is the desired protocol to filter, offset is the position of the value in the header, size is the length of the data you are looking for and value is the data you want to find.
