[Ns-developers] NS-3 sockets data sent callback, again

[Gustavo Carneiro]

  I'd like to draw attention to
http://www.nsnam.org/bugzilla/show_bug.cgi?id=131#c2

  I had already discussed that the "output callback" in NS-3 sockets is not
in conformance with the BSD sockets interface.  IIRC the responses at the
time were like "NS-3 interface is simplified".  As I already suspected back
then, this interface makes life more complicated, not easier, and I request
reevaluation of the output callback interface.  In my opinion it really
should stick to BSD socket semantics, i.e., the output callback should be
called when the socket has buffer space available to accept more data from
the application, not when some data has been sent.
