<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>i would like to know how reliable NPF timestamps
are. When i capture the traffic i created with an application using PACKET.DLL
between two notebooks, i note that they are very strange. I've tried to capture
with Wireshark too, but the results are the same. If i measure interspace time
between two consecutive frames, i see very often that the timestamps indicate a
too short interval. For example, wireshark gives me these two
lines:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial
size=2>No. Time Source Destination Protocol Info</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>...</FONT></DIV>
<DIV><FONT face=Arial
size=2>9 0.000911 xxxx ...</FONT></DIV>
<DIV><FONT face=Arial
size=2>10 0.000912 xxx ...</FONT></DIV>
<DIV><FONT face=Arial size=2>...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>How possible that a frame is arrived after one
usec? The traffic i create is done with a nominal interframe time of 0.01 ms
(that should be over the effective router capacity).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I'm using a 802.11N router with PCMCIA wireless
card with atheros chipset AR5008 and Windows XP/Vista on the two
notebooks.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Who can help me?</FONT></DIV></BODY></HTML>
