WinPcap capture with Jumbo frames</DIV>
<DIV><BR></DIV>
<DIV class=Section1>
<P class=MsoNormal><SPAN style="COLOR: #1f497d">Hi WinPcap
users,<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: #1f497d">I’ve used winpcap library in
my application to capture TCP/IP packets and extract DICOM info from those
packets.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: #1f497d"><o:p> </o:p></SPAN></P>
<P class=MsoNormal>It looks like the <SPAN
style="COLOR: #1f497d">Winpcap</SPAN> is only able to capture “normal” size
ethernet frames(1600 bytes) and not jumbo or super jumbo frames(e.g. 16kb).
<o:p></o:p></P>
<P class=MsoNormal>Maybe the default setting of WinPCap is to capture only
normal size frames?<o:p></o:p></P>
<P class=MsoNormal> <o:p></o:p></P>
<P class=MsoNormal>Can we configure ethernet frame size in
WinPCap?<o:p></o:p></P>
<P class=MsoNormal>We are missing DICOM data in case of Jumbo frames in Fast
gigabit Ethernet.<SPAN style="COLOR: #1f497d"><o:p></o:p></SPAN></P>
