<DIV><FONT size=2>Hello,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I am trying to model a wireless link empowered with
link-level recovery as an error-free link with variable bandwidth.</FONT></DIV>
<DIV><FONT size=2>I suppose link-level loss recovery (such as snoop or
combination of FEC+RLP) can completely hide link-specific
errors.</FONT></DIV>
<DIV><FONT size=2>Dupacks are assumed to be either eliminated at the wireless
link (by snoop) or ignored at the TCP sender (by TCP-Eiffel). The only way
that a link-level error can be seen by upper-layer is by link-level timeout
(in the snoop), which is assumed to be very rare.</FONT></DIV>
<DIV><FONT size=2>IMHO, this link will be seen to upper-layer as an
error-free variable bandwidth link, but unfortunately I find it difficult
how to actually model it.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I would be very grateful if one of you kindly give me a piece
of advice.</FONT></DIV>
<DIV><FONT size=2>Thanks in advance.</FONT></DIV>

<DIV><FONT size=2>PS : Intuitively, any shared medium access link (including
Ethernet) could be modeled as a variable bandwidth (or variable delay) link. Is
this wrong, or just hard to do?</FONT></DIV>
