FWIW, our router at MAE-East says: IP packet size distribution (38569M total packets): 1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480 .000 .400 .046 .016 .018 .012 .008 .009 .011 .012 .006 .007 .005 .004 .004 512 544 576 1024 1536 2048 2560 3072 3584 4096 4608 .010 .006 .120 .000 .099 .197 .000 .000 .000 .000 .000 It's been up for some weeks and the sample size is, well, OK. As expected, large number at the low end, but I'm not sure what to think about the 2048 slot. I would have thought that once packets are bigger than ethernet MTU, they would also be bigger than 2048. If the numbers are true, then close to 1/3 of all packets (1536 slot plus 2048 slot) are larger than 576. -- ------ ___ --- Per G.
