The question is whether "some data" is better than "no data". Honestly, I'm not sure.
Yes, Patrick, I was just trying to be diplomatic about saying "not such a good idea" so he'd keep reading through to the end, where I suggested some other, possibly better, research topics. I am, however, certain that other people could suggest even better research topics. Good research topics are in demonstrably short supply among networking grad-students, so if y'all want to be helpful...
I'm currently looking for data characterizing BGP updates. This page calls out 'bad' guys: http://bgpupdates.potaroo.net/instability/bgpupd.html but I haven't found anything yet which defines the terms or methodologies used. Is there a key for this page somewhere? Are there similar data sources for BGP update stats that go into more detail? I'm personally interested in being able to tell the difference between new announcements/withdrawals of a prefix to the Internet as a whole (insufficient redundancy?) vs. changes in best path (next hop). If I can get my hands on raw BGP update traffic info, I would even consider taking a stab at doing the analysis myself. Pointers to data/previous results (as well as comments on why this is a stupid question) are welcome. Thanks, Bill Bogstad
