Subject: [afripv6-discuss] IPv6 rollout? 
X-Mailer: Apple Mail (2.1485)

Hi Guys,

So, while i'll be sending out a lot more data soon, with a lot more information 
on exactly what we did and how we did it etc, I thought  I would share some 
news that I for one found rather exciting.

Yesterday evening starting at around 7pm one of the South African universities 
turned up IPv6, in a fairly consistent manner.  Now, I'm not talking about 
turning up IPv6 on a few servers, I'm talking about integrating it into every 
part of their network.  By 2:30am this morning it was running on all their 
proxy servers, all their residence networks, the wireless networks, all the lab 
PC's and a good portion of the staff network.  The topology used was identical 
to that of the IPv4, and as the rest of the network is migrated to the new IPv4 
topology V6 will be implemented on everything in dual stack along side that as 
well.

Now, here is where things get interesting, another network dual stacked is no 
real news, so lets talk about traffic levels.

The University in question is now running anywhere between 30 to 50 percent of 
its internet traffic on IPv6, and its working flawlessly so far.  So flawlessly 
infact that even with Apple's default implementation of Happy Eyeballs that 
tests RTT and defaults to v4 if the v6 latency is higher, the apples we tested 
on running lion and mountain lion were still choosing ipv6 most of the time.

I am not going to say this little rollout has been easy though, we had to 
rearchitecture the entire network (that had to happen anyway for various 
reasons), and we added the v6 as part of that project.  It would not have been 
possible to do that without first getting our hands on another /15 worth of 
IPv4 space though to allow that rearchitecturing to happen properly.

As I said though, in coming days we'll write up what we did with a lot more 
detail and send through some graphs and other information, I just had to share 
the fact that we're seeing at points half the traffic on a standard university 
coming in from the internet over ipv6!

Thanks
