[ns] Problem generating a Trace File

Dear all, I am new to NS and I am sucked with a problem that I can't solve, I need to generate tarffic with arbitrary sizes, I mean each packet with a diffrent size, I know how to generate traffic using CBR with fixed packet size (this is simple), but I think I must use trace file as input, I
