title: How could I find or calculate the throughput, delay, and packet loss rate of TCP flow from the pcap file, using Python?

  <blockquote>
  <ol>
  <li>I want to do it from reading the <strong>pcap</strong> file , and using <strong>Python</strong></li>
  <li>Now I use the <strong>dpkt</strong> module to caculate the throughput of TCP flow, accumulate the total length of all packets of one TCP flow, and
  divide total length by (endtimestamp - starttimestamp), is it correct?
  And how to find delay and pcaket loss rate?</li>
  <li>The data was captured in LTE network.</li>
  </ol>

  <p>Thanks a lot.</p>
