(Sorry if this goes to the list twice, I accidently sent it last time from
an unsubscribed list)
Tenet currently uses telkom as a service provider. To my knowledge (and Im
open to correction here), Telkom has been looking at v6 for a while now,
however they are at this point not ready to roll out native v6 on their
network. When this will happen Im not sure.
As a result, we needed transit, to this end I approached both Occaid and
RealRoute international, who kindly agreed to give us v6 transit as an
educational institution. (The realroute transit is temprorary until such
time our other means of transit via another source goes live). (Many thanks
to both Occaid and RealRoute for this btw).
These tunnels run to endpoints in europe with the v4 tunnel backend going
over Telkom current infrastructure, with what is actually incredibly low
latency (about 153ms on the faster of the 2, which is only about 2ms higher
than the latency over v4 to the european based v4 router we use)
As a result, the v6 connectivity for Tenet at the moment is actually very
very efficient (and in the case of US connected v6 hosts, like
ftp.freebsd.org, the connectivity over the v6 tunnels via our transits is
actually BETTER than going native v4 via our upstream to the states. (With
about 400% increase in transfer speeds over FTP when using v6 versus the
purely because the route it takes via v6 is better than the upstream v4
As a result of this, while obviously this is up for much discussion and
view point could drastically change, and this is merely my own personal
viewpoint, even if our upstream providers did go native v6, while obviously
we would like to utilize that, we may well decide to also keep our Occaid
transit tunnel in place as a backup, and also as a primary route in some
cases because of how efficient it has proved to be.
By the way, as a side note, Tenet opted to go for a FreeBSD routing
for v6 for now, and while this could change in the future as we move
forward, I just wanted to stress to those looking at v6, that you do NOT
need to invest large amounts of money in new routers, IOS upgrades on your
routers etc in order to do roll out v6 routing. Using FreeBSD and doing
announcements from FreeBSD based platforms works like a dream, and if
wants more information on this, feel free to contact me.
Anyway, thats just a bit more information.
