Please Help, its a bit urgent.
Hello,
I am currently doing a project on Multimedia Streaming and want to simulate
it using NS2. I searched the Mailing Archives and I found some previous work
done in this area by 'smallko'.
I got his files 'mpeg4_traffic.cc' and all. But I am facing some problems
using it. I followed the following steps:
1.) Downloaded the files. Saved the file 'mpeg4_traffic.cc' and the folder
'Video_Model' in a new folder named 'MPEG4' in the ns-2.31 directory.
2.) Added the following in the MakeFile
'MPEG4/mpeg4_traffic.o \'
under 'OBJ_CC'
3.) Performed 'make depend', 'make' and 'make install' in the ns-2.31directory.
4.) Then, I used the file 'part-of-example.txt ' to write a TcL code and
saved it in ns-2.31/tcl/lib
5.) Tried to run this file, but gives me the following error:
invalid command name "Application/Traffic/MPEG4"
while executing
"Application/Traffic/MPEG4 create _o84 "
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 Application/Traffic/MPEG4"
invoked from within
"set vdo [new Application/Traffic/MPEG4]"
(file "part-of-example.tcl" line 79)
I have attached the TcL code which I was trying to run. You can see traces
of Mark Claypool's Simple Simulation Example in the code. :)
Hoping for a swift reply. Thank You.
P.S.: I am using NS-2.31. Output of uname -a
