[ns] Problem with RSVP

[Elena Scialpi]

   I have problem running RSVP(rsvp patch file - 2.1b8)/NS(ns-2.26).
when I run ns rsvp_conf.tcl, I get the following error:

(_o3 cmd line 1)
    invoked from within
"_o3 cmd duplex-rsvp-link _o10 _o17 1Mb 1s 0.3 50 5000 Param Null"
    invoked from within
"catch "$self cmd $args" ret"
    (procedure "_o3" line 2)
    (SplitObject unknown line 2)
    invoked from within
"$ns duplex-rsvp-link $n0 $n1 1Mb 1s 0.3 50 5000 Param Null"
    (file "rsvp_conf.tcl" line 42)

What kind of error it is?
Please, help me!
Thanks,
Elena
