<TITLE>TCP RFC's implementation Status</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>Hi,</FONT>
</P>
<P><FONT SIZE=2>I searched the list but couldn't find a site or message with the current TCP RFC's implementation status. There are a plethora of TCP extensions and since I'm coding a TCP Proxy I would like to know which ones are actually implemented out there. I'm interested on the availability of ECN, SACK, Limited Transmit, Eifel, etc, etc on Linux, windows, etc, etc.</FONT></P>
<P><FONT SIZE=2>I know that SACK seems to be widely avaialble, but not sure about all the others...</FONT>
