Hi,
I have never done anything with TCP layer, so I'm not sure.
But a general rule I summarized is that
1) If the two layers you want to cross-access are adjacent, you can use
uptarget_/downtarget_
2) If they are not, it is a bit of difficult to make the pointer clear. My
Hi Basim,
The connection from a node to a TCP agent is fairly subtle. Basically, a
Node has an instvar dmux_ which is a classifier. It install a TcpAgent
and TcpSink in the slot of the classifier dmux_. This occurs when
you invoke commands like
$ns attach-agent $n0 $udp0

Hi,
I don't think you want to classify packets in mac layer. Instead, you want
your packets to be submitted to aodv. Thus, in aodv.cc, you need to identify
your packets in AODV::recv(Packet *p). In fact, as you know, all packets first
arrive at such a recv function in any layer. So if
