Network - Over 10k users. Common bandwidth to INTERNET more then 1 GBs
All computers have BGP and turn on multipath.
Cisco can't do load sharing by Packet (its can resolve all my problems 
=((( ). Only by DST IP, SRC IP, or +Level4.
Ok. User must have speed 1mbs.
Lets look variants:
1. Create rules to user = (1mbs/N computers). If user use N connection 
all great, but if it use 1 connection his speed = 1mbs/N - its not look 
good. All be great if cisco can PER PACKET load sharing =(
2. Create rules to user = 1mbs. If user use 1 connection all great, but 
if it use N connection his speed much more then needed limit =(

Why i use 20 PC? Becouse 1 pc normal forward 100-150mbs... when it have 
100% cpu usage on Sofware Interrupts...

Any idea how to resolve this problem?

In my dreams (feature request to netdev ;) ):
Get PC - title: MASTER TC.  All 20 PC syncronize statistic with MASTER 
and have common rules and statistic. Then i use variant 2 and will be 
happy... but its not real? =(
Maybe have other variants?


Thanks for help!
Slavon.
P.S. Sorry for my english =(
