[ns] error in BLUE implementation

[alok kumar]

hi everyone

  I am trying to run the BLUE AQM algorithm in ns-2 using Sunil
thulasidasan's implementation. I followed the instructions but i am getting the
following error:


can't read "q": no such variable
    while executing
"$q link [$link_($sid:$did) set link_]"
    (procedure "_o3" line 8)
    (Simulator simplex-link line 8)
    invoked from within
"$ns simplex-link $n1 $n2 1Mbps 100ms Blue"
    (file "test-blue.tcl" line 41)



Can anyone help me on this please?


thanks
