[Planetlab-users] Bandwidth

[Alex Sherman]

Robert,

does BWLIMIT specify the cap for the physical machine or for each
individual sliver on that machine ? If BWLIMIT is for the whole machine
is that shared evenly by all slivers on that machine ? Is there some
way that I can get the value of the cap for my sliver or there is no
such thing ?

thanks again for your reply

-Alex
