[ns] window probing in ns

[gmc50 <gmc50@student.canterbury.ac.nz>]

Hi,

Since ns-2 does not support dynamic advertised window, I suppose that it
does not support zero window probe. Is this assumption correct?  (that
is, if the advertised window (window_) = 0, does ns-2 support sender
timer freezing and sending probe packets with exponential backoff (RFC
1122) to probe for a new advertised window?)

If ns-2 does not support such sender action, is there any practical way
to implement this action or has anybody done this before?

Thank you in advance for your help,

Gustavo.
