Hi, Does anyone have any /recent/ information on the breakdown of packet sizes crossing the net right now? I have seen some of the older data, but am interested in whether or not the percentages are changing over time, and if so, how. I.e. I could see people moving from interactive services such as telnet for reading mail and news to going to a client based system would up the packet sizes. Likewise, the use of some of the streaming video and audio applications out there might lower it again. In my mind, recent is anything that has been done in the last 6 months or so.

i can't give you historical data but here's current netflow data from our mae-west (san jose, not nasa/ames) and mae-east peer routers: peer1.sjc1#sh ip ca fl IP packet size distribution (9577M total packets): 1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480 .001 .500 .032 .013 .016 .009 .009 .009 .020 .017 .006 .009 .009 .007 .003 512 544 576 1024 1536 2048 2560 3072 3584 4096 4608 .008 .004 .088 .042 .188 .000 .000 .000 .000 .000 .000 peer1.wdc1#sh ip ca flow IP packet size distribution (12535M total packets): 1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480 .000 .646 .045 .010 .010 .005 .006 .005 .015 .013 .015 .009 .005 .005 .003 512 544 576 1024 1536 2048 2560 3072 3584 4096 4608 .003 .006 .095 .014 .078 .000 .000 .000 .000 .000 .000 i guess everyone is pinging these days :) -brett
