Hi,

how can we get drop packets during a simulation?

What do you mean by drop packets? Packets don't just disappear for no
reason in real world. Are you saying you want to drop packet because
buffer's full? Packet drop because of collisions in wireless
situation? packet drop because SINR is too low in wireless situation?

yes, when I said lost packets i was referring to, for example, lost
packets because the buffer is full.
How can I get the value that represents the number of packets lost?

Have a look at the TraceSources for the specific implementation of the
NetDevice/MAC. Eg. A CsmaNetDevice has "PhyRxDrop", WifiPhy has
"MacRxDrop", etc.

Hi Bruno,

You need to read the tutorial document, particularly the Tracing
Section, in order to get comfortable with trace sources and sinks. You
can see the whole list of trace sources in

http://www.nsnam.org/doxygen-release/index.html

under Modules -> Core -> The list of all trace sources.

As a tip, the trace source you're looking for is MacRxDrop, I guess.

Best regards,
S�rgio Figueiredo

Quincy, thanks for the help! Now i'll try to see how TraceSources works.

Hi Sergio,

actually i have read a little bit of the Tracing Section tutorial but now i understand that i must read it entirely... Yes, this is what i'm looking for.

Thank you for the reply

"Obrigado"
