Wouldn't it be nice to have mrtg graphs of both WIX and APE like whats been done with LINX http://www.linx.net/tools/stats/index.thtml
It would indeed but life isn't always as straightforward as we'd like! I'd conjecture that the LINX total volume measures are calculated by summing all the traffic injected into the Exchange (both byte and packet stats). (Or you could measure all the outbound stats instead). The WIX peering environment runs on top of Citylink's Ethernet network which has over 60 switches distributed across the city. Some customers peer with the WIX route servers, some don't. For those that peer some proportion of their traffic in/out of their switch port is being routed based on information gleaned from the route servers and some is destined for their ISP based on a static route in many (most?) cases. So it's far from obvious how we'd measure the "WIX traffic" and aggregate it up for display. The APE is closer to the LINX model but there's still some proportion of the traffic that isn't peering related on the switches we manage and there's peering traffic that's part of the APE environment that doesn't traverse those switches so I'd be reluctant to publish statistics that weren't measuring what they claim to measure! That's not to say we aren't thinking of ways to catalogue and measure the benefits of having the exchanges. Perhaps measures of the round trip times between various points on the network would be of more interest. A job for the lads at Waikato's WAND group funded by InternetNZ?
