Fw: [afripv6-discuss] IPv6 - The current status in the tertiaryeducation sector in South Africa

(Sorry if this goes to the list twice, I accidently sent it last time from 
an unsubscribed list)

Hi Jordi,

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 
v4,
 purely because the route it takes via v6 is better than the upstream v4
 route)

 As a result of this, while obviously this is up for much discussion and 
this
 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 
solution
 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 
bgp
 announcements from FreeBSD based platforms works like a dream, and if 
anyone
 wants more information on this, feel free to contact me.

 Anyway, thats just a bit more information.

 Thanks
