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?
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).
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?
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
