Post vbr dealy and problem


Hi
Sorry to tell you that I still have problem in simulation of vbr. Because when I was trying to create the traffic with vbr it was not working properly. because rate was took as rate=0.0.and the delay was more than 100. And It was working fine with cbr.

I want to ask one thin that the in above message said addition of indep-utils/webtrace-conv/dec/Makefile : CC = g++-3.3 but while insertion of vbr I used in ns-2.34 of make file cc=gcc-4.3 and ccx= g++-4.3. So it make any difference to that files. Because g++-3.3 is lower version than g++-4.3.

I am doing my project on vbr and tcp traffic with 100 nodes with DSR
Please help its really urgent to me.......

Thanks in advance

with regards
Khan

# 16, @ khan1354.

I don't remember why I wrote g++-3.3 in post #15.

g++-4.3 should do OK in ns-2.34. And : It really doesn't matter. AFAIK.
As long as it gets compiled, and you have the binary : dec-tr-stat

( ns-allinone-2.34/ns-2.34/indep-utils/webtrace-conv/dec/dec-tr-stat ).

ns234 cbrgen.tcl -type vbr -nn 100 -seed 1.0 -mc 20 -rate 4.0
Looks OK here. See the attachment.
