Re: Buying IP Bandwidth Across a Peering Exchange

The way our exchange works is 2 different products in regards to this.

1.Peering on the exchange.  This is a BGP exchange.
2.Private VLAN.  Each side gets a private VLAN between the two.

Either way you buy capacity on the exchange and it¹s up to you how you use
it.

I have some Equinix documents on their exchange port offerings if you are
interested.

Hi Colton,

The primary challenge in buying IP Transit across a Peering Exchange is
not so much of a technical configuration challenge, but rather a 'how do
we keep track of how much IP Transit you are using' ..a billing challenge.

and additionally, one is making the assumption that there is capacity to
do so on the IP Transit Providers Peering Port Connection.

While it is possible to deal with such issue, but you need someone
willing and able to do so, on the other side.


------------------------
I think the way most providers would do this would be to get a rack and
power with Equinix. Pay a cross connect fee from the wave provider to
our
rack. Pay for an exchange port (which includes a cross connect to the
exchange) for the 5GBPS of traffic going to Netflix, Google, etc. And
then
pay for yet another cross connect going to HE.net's cage to get pure IP
from them.
-------------------------

Yes, you are right, this is the traditional way of doing so, and yes, it
can get expensive.. For this exact reason, folks such as us and others
who are willing to provide access via their existing resources at
different facilities.

We are facilitating flexible connectivity needs of folks who are running
remote (from major metro areas) such as yours, in Miami, Atlanta, and I
know others who are doing so in Equinox Chicago, one in Texas and a
couple of the West Coast.

Feel free to ping me off list if you are interested in additional details.

The exchange in question is Equinix. Their sales team is leading me
to believe there are multiple exchange products. One where you can peer
with providers (Google, Netflix for example) and then one where you can
create virtual private layer 2 vlans between providers. Then there is
also
the traditional cross connect fee of $350 if you want to go from one
cage/rack to the other.

So in a situation where we are getting a 10Gig transport wave to
Equinix,
we would ideally like to split this wave's use to 5Gbps of traffic
going to
the peering exchange for traffic going directly to Google, Netflix, and
other CDN's, and then 5Gbps of pure IP transit going to a low cost
provider
like HE.net. Of course providers like HE.NET are also peers on the
peering
exchange, so it seems possible that we could just opening a peering
conenction with them.

I think the way most providers would do this would be to get a rack and
power with Equinix. Pay a cross connect fee from the wave provider to
our
rack. Pay for an exchange port (which includes a cross connect to the
exchange) for the 5GBPS of traffic going to Netflix, Google, etc. And
then
pay for yet another cross connect going to HE.net's cage to get pure IP
from them.

If I can buy transit directly I avoid the expenses of having to pay for
space, power, another router/switch, plus a second cross connect. Thats
quite a bit of money saved.

Are exchanges really that unreliable compared to a traditional cross
connect?

Hi Conor,

I know this is possible since Hurricane Electric does it for IPv6
transit,
however, I'm not sure if it violates any exchange rules or if it's
even a
good idea.

I know typically peering exchanges are made for peering traffic
between
providers, but can you buy IP transit from a provider on an
exchange? An
example, buy a 10G port on an exchange, peer 5Gbps of traffic with
multiple
providers on the exchange, and buy 5Gbps of IP transit from others
on the
exchange?

Some might ask why not get a cross connect to the provider. It is
cheaper
to buy an port on the exchange (which includes the cross connect to
the
exchange) than buy multiple cross connects. Plus we are planning on
getting
a wave to the exchange, and not having any physical routers or
switches
at
the datacenter where the exchange/wave terminates at. Is this
possible?
