insertion of vbr and VBR end end delay more
 
Hi this is sam I am using Ubuntu marvic amd64 10.10.
I installed ns-allinone 2.34. then I inserted vbr traffic according to one of forum from this linux " Insertion steps of VBR into NS2.34"

I made the following changes
Makefile, line 36 : CC = gcc-4.3
Makefile, line 37 : CPP = g++-4.3
vbr_traffic.cc in ns2.34/tools then Makefile : tools/vbr_traffic.o\ of 183
then I use the command
cd ns-allinone-2.34/ns-2.34/ && mv ns ns234 && make after that I delete the ns.
with the new command I run the script with every time puase time 0 and simulation time 200, 10 250, 20 300, 40 400..... with DSR after completion of simulation, when i was try to plot graph between throughputs of receiving bits vs Maximul end to end delay, every time I got the delay more than 90, 100, etc
so how can I reduce that problem. please help me its really urgent to me.

I thought problem was in insertion of vbr.

please help me if any ideas on this I would happy for that
thank you
with reagards

insertion of vbr and vb delay
 
I want to to tell u one thing that when run the simulation with cbr traffic, the rate was utilized properly bus for in vbr traffic its showing as I saw in generated traffic file.

this 100 nodes with 20 pause time of 1000*1000
I made made the cbr traffic as follows
ns234 cbrgen.tcl -type cbr -nn 20 -seed 1.0 -mc 10 -rate 6.0 > c100 and it generated as

nodes: 20, max conn: 10, send rate: 0.20000000000000001, seed: 1.0 it showed me 25 maximal end to delay

this is also 100 nodes with 50 pause time of 1000*1000
and for the vbr traffic as follows
ns234 cbrgen.tcl -type vbr -nn 20 -seed 1.0 -mc 10 -rate 6.0 > p50 and it generated as
nodes: 10, max conn: 5, send rate: 0.0, seed: 1.0
and i tried for other pause time also its same showing rate was 0.0

I thought main problem was in insertion of vbr. please help me of this one. this is really urgent to me. please help me

thanks

with regards
sam
