hi to all,
I'm trying to trace SCTP trafic,to explore the cwnd and rto values.
Unfortunately when I added the suitable lines to trace the agent I got this
error.
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o51: no target for slot 0
_o51 type: Classifier/Hier
I need your help to resolve this problem.Do you have any advice?
Below are the lines that I've added to trace agent trafic
set sctp0 [new Agent/SCTP]
$ns_ multihome-attach-agent $sgsn $sctp0
$sctp0 set fid_ 0
$sctp0 set debugMask_ -1
$sctp0 set debugFileIndex_ 0
$sctp0 set mtu_ 1500
$sctp0 set dataChunkSize_ 1448
$sctp0 set numOutStreams_ 1
$sctp0 set oneHeartbeatTimer_ 1
$sctp0 set initialCwnd_ 2
$sctp0 set useMaxBurst_ 1
$sctp0 set trace_all_ 1
set trace_ch [open trace.sctp w]
$sctp0 trace cwnd_
$sctp0 trace rto_
$sctp0 trace errorCount_
$sctp0 attach $trace_ch
