Hmm. I should have provided more detail...
Valdis is correct. We are a cost recovery organization. We
currently offer 10 or 100Mbs ports to the desktop. The switch port itself
is usually at fixed price based on an average number of active ports per
switch. Wiring is usually offered at a standard price, unless getting the
wire to the desktop requires difficult things like core drilling through
heavy masonry, etc. We consider core switches, fiber, building entrance
switches, WAN links, and other ancillary equipment to be infrastructure,
that is paid for out of a central fund.
We/I believe that there are some circumstances where there are
large compute clusters, typically doing either simulations or large image
manipulation (think of the various types of radiology), that may justify
something in excess of 100Mbps. We do have several of these that we know
Furthermore, there are what a colleague at another university
refers to as the "800 pound gorillas", that have the weight, and perhaps
the funding, to effectively press for higher speed service, whether or not
such speeds are justfiable. In the past we have been known to build
non-standard services on an as needed basis, where the customer paid full
freight for everything required because we were unable to spread the cost
over a user base, due to the uniqueness of the request.
So, we are looking for clues about how to build such a model.
Thanks for any ideas, current models, war stories, etc.
