These numbers may vary quite a bit depending on the nature of your "real
internet traffic".
IP packet size distribution (34510M total packets):
1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480
.003 .316 .033 .024 .021 .018 .011 .010 .013 .013 .009 .010 .006 .006 .007
512 544 576 1024 1536 2048 2560 3072 3584 4096 4608
.005 .005 .413 .017 .049 .000 .000 .000 .000 .000 .000
