[ns] Add New Queue, Trying to get 802.11e working on "ns by example"

[Sim Tec]

Hey all, after trying to get 802.11e in many ways, many packages, i have
started trying to do it through "ns by example".

I have the multimedia application running correctly

I encountered problems getting the "add new queue" working.
I have put dtrr-queue.cc and dtrr-queue.h
running  ns ex-dtrr-queue.tcl,


invalid command name "Queue/DTRR"
    while executing
"Queue/DTRR create _o68 "
    invoked from within
"catch "$className create $o $args" msg"
    invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
global errorInfo
error "class $..."
    (procedure "new" line 3)
    invoked from within
"new Queue/$qtype"
    ("default" arm line 3)
    invoked from within
"switch -exact $qtype {
ErrorModule {
if { [llength $args] > 0 } {
set q [eval new $qtype $args]
} else {
set q [new $qtype Fid]
}
}
intserv {
set qtyp..."
    (procedure "_o3" line 14)
    (Simulator simplex-link line 14)
    invoked from within
"_o3 simplex-link _o16 _o19 2Mb 10ms DTRR"
    ("eval" body line 1)
    invoked from within
"eval $self simplex-link $n1 $n2 $bw $delay $type $args"
    (procedure "_o3" line 8)
    (Simulator duplex-link line 8)
    invoked from within
"$ns duplex-link $node_(r1) $node_(r2) 2Mb 10ms DTRR"
    (file "ex-dtrr-queue.tcl" line 48)


All help appreciated,
