WIX changes Monday 13 June 2011
Hi all Around ~4am Monday morning I'll be moving ~35 of the busier peers on WIX into the new(ish) shiny(ish) dedicated-to-WIX vlan on Citylink. There will be an infinitessimally small outage for each peer being moved (long enough for "switchport access vlan" to take effect, and some MACs to be relearned), and I'll test each peer as I go for reachability. So there shouldn't be any particular impact to customers or the IX as a whole. The peers getting moved (and the others getting left behind) is discussed in gory detail at: http://scorchio.pure-guava.org.nz/posts/WIX_VLAN_Migration/ Cheers Simon -- Simon Blake simon(a)katipo.co.nz Geek for hire +64 22 402 0044

Woohoo! This is great news for those who've been asking for this for years. Thanks :)
Does this mean we might soon get to hear real peering traffic statistics for the IXPs, so that we might understand the traffic volumes in NZ a little better? Your blog post mentions the filtering bridge can do about 500Mbps and that should be fine, does that provide us a hint to the volume of traffic on WIX?

In the past, particularly in Wellington, the input sum of all the ports that had a MAC that was responding to a WIX IP address would have given a picture of WIX that was skewed to the point of uselessness, as most ISP's were also running transit operations on the same interfaces. As most ISP's have now moved their transit operations on Citylink into their own vlans, this is much less of an arguement - once FX and Vector are moved across, it ought to be possible to produce a graph that "is" WIX. Whether Citylink think such a graph should be public, that's a policy question for Citylink to answer. Technically, it's a lot closer now than in the past (at least in Wellington).

Not really, in that I was talking about how much traffic would go between the bulk of peers already in the WIX vlan, and the few remaining, as listed at http://scorchio.pure-guava.org.nz/posts/WIX_VLAN_Migration_part_2/ So traffic within the 100, and within the 25, doesn't cross the bridge, and so isn't relevant for the sizing of the bridge. My guess is that were one trying to run all the traffic on WIX through a central point, one would need need more than 500Mb, possibly more than GE. However, that's largely based on gut feel - there are now a significant number of peers on GE, and a few on 10GE. I haven't seen a working aggregate graph of all the WIX ports, so I'm as much in the dark as everybody else. Cheers Simon -- Simon Blake simon(a)katipo.co.nz Geek for hire +64 22 402 0044

Indeed. I was one of the annoying people who insisted on separate ports years ago, for this reason (and because my peering interfaces were on different routers from access..).

I surely hope that Citylink will make this available, if not publicly then at least for the IXP participants. And I'd love for it to be available for APE and the other IXPs as well. It would allow a /lot/ of uninformed speculation to become semi-informed fact.

That is interesting and approximately in-line with what I was thinking about WIX too. regards, aj
