as would be solving world hunger, war, bad cooking, especially bad cooking. route leaks, as much as i understand them o are indeed bad ops issues o are not security per se o are a violation of business relationshiops o and 20 years of fighting them have not given us any significant increase in understanding, formal definition, or prevention.
let me try to express how i see the problem. to do this rigorously, i would need to form the transitive closure of the business policies of every inter-provider link on the internet. why i say it is per-link and not just inter-as (which would be hard enough) is that i know a *lot* of examples where two ass have different business policies on different links. [ i'll exchange se asian routes with you in hong kong, but only sell you transit in tokyo. we have two links in frankfurt, one local peering and one international transit. ] it is not just one-hop because telstra was 'supposed to' pass some customers' customers' routes to optus. i find this daunting. but i would *really* like to be able to rigorously solve it. please please please explain to me how it is simpler than this. randy
