Traffic Volume Manager ? (Previously: RE: Regional differences in P2P)

["Hendrianto Muljawan" <muljawan () siemens com>]

Hello,

the discussion here is getting interesting for me, because people are
talking about not only capping the Bandwidth but also capping the volume
of the traffic sent by a customer.

So far people are used to do the capping of bandwidth with a Bandwidth
Manager device, which does traffic shaping based on e.g.
application/protocols, etc.

Now, since we are talking about capping on the volume, what is the
product available on the market which can do both bandwidth and volume
capping ?

thanks,
Muljawan

Ridiculous is the word here. Download two service packs and you're done
for the month? I can understand this happening in Brazil or India, where
caps are a tool to attract enough customers so they bring revenue that
in turn will be re-injected in much needed backbone upgrades, but in
Norway or the US it does not make a lot of sense to me.

There is a need for capping 10 and 100 meg residential though; if you
want to run your 100 Mb/s pipe full all the time it represents 26TB per
month in each direction; you can't give 2/3rds of an OC-3 to a customer
for $110/mo. A 300GB/mo cap means that the customer is using their line
an average of 1.15%, which brings the interesting question of what a
reasonable speed/cap ration should be.

  1.5 Mb/s =    389 GB/mo
 10   Mb/s =  2.6   TB/mo
100   Mb/s = 26     TB/mo

Speed/cap ratios:
  1.5 Mb/s capped at   1 GB/mo = 0.25% ridiculous IMHO
 10   Mb/s capped at  40 GB/mo = 1.54%
100   Mb/s capped at 300 GB/mo = 1.15%

Thoughts, anyone?

Michel.
