Is it possible to implement a simple ACK
filter-like protocol (where an intermediate node simply drops some of the ACKs
on the return link) in ns-2 WITHOUT coding a new protocol in C++ ? ie: I
wish to simply implement this in a tcl script, perhaps by using the
trace-callback function.
I already know the basics needed to use the
trace-callback feature in ns-2, but I need to know if there is a way to "drop" a
packet.
eg. trace-callback function:
if (packet is an ACK) {
if (this ACK should be dropped)
{
schedule event to delete
ACK from stream (ie: don't forward to next node)
}
}
else {
do nothing
}
Any help would be great.
