Re: Coop Peering Fabric??

Speaking of AtlantaIX, the new business model seems less attractive for
customers than the old one.  Can anyone speak to why it got sold?  Was it
failing financially or someone just wanted to cash out?

People are.  I (and others) mentioned SIX & TorIX, plus I mentioned PaNAP.
 Then there's AtlantaIX, although that recently got slurped by TelX.
 (Hrmmm, could one of the "dangers" of a coop be "borg'ed by for-profit
entity looking to rip out every cent they can"? :)

Tons of others exist, in big and little markets.  There's one in 365 Main
SF, there's KleyReX in the same building as DE-CIX, Big APE in 111 8th, NYCx
there too, ChicagoIX just opened, etc., etc.

Trust me, it _is_ being done.


Also, does your Equinix MSA contain a non-compete clause, which could
be interpreted to mean you can't run a competing IX (metro fabric,
exchange, whatever) out of their facilities?  I hear many do.


So don't run it in an Equinix or S&D cage.

Given Cogent (and others) recent pursuit of sub $4/mb/s transit... and
the
relatively flat cost of a "paid" peering fabric (even at 10G) and the
O(N)
costs for cross-connects, the thought of revisiting the old peering coops
presented itself again.

Assuming 10G PNI model: Assuming even nominal cross-connect fees of
$100-$300/month per fiber pair, plus router port costs for each private
peer
(assuming you aren't at >10% utilization on the port) at a commercial
exchange, you are eating a pretty significant cost per megabit you are
actually moving. (plug in your numbers here). Assumption: Above 1Gb/s
utilization, this makes sense or you are counting on growth.

Below 10% you would normally go to a paid peering fabric where you are
paying cross connect + a flat port charge + router port for 1->N peers
and
hoping that enough utilization occurs that you get >10% utilization (to
recover capex, opex, etc) and then whatever additional utilization you
need
to cover the flat port charge or you are counting on growth.

A "coop", best-effort switch fabric colo'd at a few sites would allow
participants to peer off traffic at a price of the order of a single
cross-connect (~$500/month per 10G port is possible, maybe less),
private-VLANs all-around, or to only-mutually approved peers (e.g. via an
automated web interface, prior art) to avoid many of the /old/ issues. No
requirement for multi-lateral peering. You could peer, sell transit, buy
transit, multicast, etc.

The way I figure it, it removes approximately an order of magnitude from
the
operational cost of peering with more than a handful of your largest
single
talkers. Especially as 100G LAN Ethernet becomes production before 100G
WAN
connections become commonplace. Economic theory (assuming that worked on
the
Internet) suggests this would allow for the increase in number of peers
by
approximately an order of magnitude (maybe more).

Does this actually improve the present-day "rationale" to peer, or are
most
operations' costs so far above (from long haul, etc) or so far below
(since
the cost of transit has dropped so much) that this is no longer a
relevant
part of the equation?

Warning: This may actually be operational too.
