There=E2=80=99s a difference between the cost and the product. As =
regards the cost, Arnold is exactly right. Across the many hundreds of =
exchanges that we=E2=80=99ve worked with over the past 22 years, our =
observation has been that, at a rough average, most IXPs spend 45% of =
their first-year effort on location selection, 45% on governance =
definition and establishment, and 10% on technical decisions and =
implementation. But the total effort and the governance portion both =
increase drastically for those that choose to handle money; at a very, =
very rough average, about four-fold. In subsequent years, location =
selection generally drops away to near zero, except in cases like the =
JINX, and technical work dips for the first couple of years, and then =
spikes once every three years or so as switches are replaced and new =
configs are needed. Many exchanges have an annual in-person meeting =
where elections are conducted and policy changes ratified, so that =
typically becomes the largest ongoing expense, as Arnold implies.
As regards the product, no, Seth, the layer 2 peering fabric is merely a =
necessary precondition for producing bandwidth. The actual bandwidth =
production has other preconditions as well: peers physically connected =
to the peering switch fabric, BGP sessions established between the =
peers, routes advertised across those sessions, a reasonable matching of =
potential traffic sources and sinks available through those routes, and =
a set of customer behaviors that prefer those source/sink matchings. =
Only then does an IXP produce bandwidth. So, the role of a salesperson =
or advocate or evangelist or tout can be a net beneficial one, if they =
do a good job of recruiting participants, making sure they follow =
through with peering, and encouraging the preference of =
locally-available content. WAIX was among the first IXPs to do this =
well, in my opinion.
