since we are on the subject of availability of good data, i'd like to ask the list what i have been contemplating for some time now. understanding of routing (especially inter-domain) in the research community is really primitive. this precludes us from having realistic routing models. we recently started working on understanding prevalent inter-domain routing policies. the ultimate goal is to improve the efficiency, robustness and expressiveness of routing protocols. http://www.cs.washington.edu/research/networking/policy-inference/ if you run a network that has choices to make (more than one BGP speaking neighbor), you can help us by donating your bgp config files. abstracted or anonymized versions are ok. http://www.cs.washington.edu/research/networking/policy-inference/donation.h... further down the road, we'll need your help to better understand our findings. if you are willing to answer our (possibly naive) questions, please respond off-list; i am compiling a list of folks whom i can pester for answers. thanks, -- ratul
