Hi,
We are in the process of evaluating different means of providing QoS
(and whether this is sane or not is not the topic of this mail :) .
The performance indications we have from our vendors are based on
different packet size distributions, so we'd like to see how the distribution
is on the Net in general.
Our own statistics show:
Router#sh ip cache flow
IP packet size distribution (93363M total packets):
1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480
.002 .433 .054 .022 .014 .012 .008 .010 .008 .008 .008 .009 .007 .006 .005
512 544 576 1024 1536 2048 2560 3072 3584 4096 4608
.004 .004 .148 .035 .194 .000 .000 .000 .000 .000 .000
But we may have a few "nonstandard" applications within our network that
could push the distribution towards smaller packets.
Anyway, if anyone could provide me with their view of packetsizes I'd
appreciate it (private mail would probably be appreciated by the list ;) .
/Niels Chr.
