So to include the exchange point
presentation I want to have a quick look
at some of the subject areas we've been
discussing.
We'll have a look at policies and politics first.
Exchange points have
acceptable use policies which are
minimum rules for connection.
We've talked about fees some exchange points
charge No Fee some are operate cost
recovery and a few exchange points
operate on a commercial basis nobody is
obliged to peer agreements are left to
the ISPs and are never mandated by the
exchange point the typical exchange
point etiquette is that members should
not point to fault rights to other
exchange point participants this should
be aware of how the bgp third-party
next-hop works and only announced
aggregate ratts
reading the ripe 399 and right 5 3 2
documents are quite important as they
describe the what is expected by network
operators for announcements to the
internet and of course filter as we've
learned in the BGP series is very very
important
filter what we sent to other peers and
filter what we receive from our other
peers the typical features we see it
exchange points our redundancy and
reliability after the exchange point
starts quite often we see a second
switch being installed quite often at a
second location a UPS is absolutely
essential and many exchange points will
often have a generator to backup the UPS
and the public power supply support is
quite often a feature well as a network
operations center providing 24 by 7
cover this nor can be provided by the
hosting facility or agreed upon by the
exchange point members we usually see
DNS rad collect and route servers
content caches and
TP servers location needs to be neutral
secure and accessible for all members as
for address space we use public
addresses for the peering land and
public addresses for the exchange point
services land an es number is required
of the exchange point operates a route
server and operates ixb services the
larger exchange points implement route
servers for scaling the BGP mesh and
statistics are very important to be made
available for the membership via the
exchange point website as for creating
exchange points no economy or
circumstance is unique or different we
quite often see excuses like oh we don't
need one or oh it's different here you
don't understand
every locality has its differences but
every locality also wants to keep local
traffic local improve network
performance and QoS for the users in
that community and improve the overall
internet economy in the locality the
available technology is the same for
every network operator everywhere so
there's absolutely no excuse for
improving the local internet economy
exchange points also help develop the
ecosystem around them we create an
exchange point Association which is
formed by the members who have a port on
the exchange part an exchange point
Association is usually what operates the
exchange point the exchange point
members meet regularly they will have
board meetings as well as operational
strategy and direction the ixb technical
community could also meet and these will
be the network operators the forks
involved in operating the network and
the systems infrastructure within each
member and these meetings could be
aligned with exchange
Association and exchange point member
meetings and it could lead to the
creation of a local network operators
group the IXP could facilitate the
creation of this nog because the same
technicians and same engineers are
involved in both a local internet
exchange point is defined as a public
peering point serving the local internet
industry and local means when it becomes
cheaper to interconnect with other ISPs
at a common location than it is to pay
transit to another ISP to reach the same
consumer base and of course local can
mean different things in different
regions a regional internet exchange
point is also a local exchange point but
they also attract regional ISPs and ISPs
from outside the locality the regional
ISPs will pair with each other at
regional ixs and indeed they will show
up at several of these regional exchange
parts a regional exchange point also
means that local ISP scan pier with ISPs
from outside the locality they don't
compete with each other and means the
local ice bees don't have to pay transit
costs and quite often ice piece of
disparate sizes and different peering
policies will happily appear with each
other because it allows all of them to
defray transit costs under word about
industry associations euro X was the
first internet exchange point
association formed of the exchange
points based in Europe Euro IX also has
associate members from around the world
and the Euro X website shown on the
screen has all the information needed to
help start an internet exchange part it
also includes the exchange point best
practice documentation mentioned earlier
in Asia there is the Asia Pacific
internet exchange association modeled on
Euro IX and members are from the
asia-pacific region it meets twice a
year during
per quart and a panic conferences other
regions of the world also have their
exchange point association we see them
farmed in Africa and Latin America as
well for further information about
interconnects tele geography maintains
an extensive list of ISP interconnect
parts be careful though these are not
all internet exchanges even though
telegraphy lists them as the internet
exchange map there is P interconnect
parts summarizing all of the discussion
about exchange points an exchange point
is a layer to infrastructure at least
three players are required to is okay as
well meeting in an open and neutral
location the need to be minimum rules
minimal BRE RSA and the need to operate
on a cost recovery basis and the
industry should encourage participation
by all autonomous networks.
The minimum requirement for each
autonomous network is that they have
their own independent address space,
their own autonomous system number
and their own transit arrangements.
An exchange point is well known and
well proven to help develop the local
internet ecosystem and are strongly
encourag ed for all regions of the world.
