title: How to create a time-space diagram showing how data is transferred in TCP?
body: <p>I need to draw a time space diagram of a client connecting to the server, then requesting data, and server sending x bytes of data then server closing the connection. </p>
  
  <p>First, I am not sure exactly how many trips back and forth there would be, I am thinking:</p>
  
  <ol>
  <li>Client requests connection</li>
  <li>Server accepts
  3  Client sends ACK</li>
  <li>Client requests data</li>
  <li>Server sends x bytes of data</li>
  <li>Client sends ACK</li>
  <li>Server closes connection</li>
  <li>Client sends ACK</li>
  </ol>
  
  <p>Is that correct??</p>
  
  <p>Also, I need to specify  SEQ, ACK numbers and SYN/ACK/FIN bits, I get the first part but what are the SYN/ACK/FIN "bits"?</p>
