<P><SPAN LANG="de-at"><FONT SIZE=2 FACE="Arial">I was wondering if anyone has a test tool to verify the correct implementation of RFC1323 RTTM (and Van Jacobson's RTO calculation with sRTT + 4 * varRTT), especially during loss recovery...</FONT></SPAN></P>
<P><SPAN LANG="de-at"><FONT SIZE=2 FACE="Arial">TBIT only verifies if Timestamp option is negotiated and properly reflected back if sent during a session, but not if the sender correctly uses the timestamps in RTO calculation...</FONT></SPAN></P>
<P><SPAN LANG="de-at"><FONT SIZE=2 FACE="Arial">And other tools which would be capable of generating arbitrary options and verifying the *packet* contents, are typically stateless and don't look at timing information by themselves (ie. scapy).</FONT></SPAN></P>
