Noting the silence, I do have one topic to suggest. In prior conversations with you, you have suggested that the broad architectural approach I prefer for path selection - i.e. topology distribution, with unified path computation (although perhaps 'monolithic' is a better term than 'unified', since the latter term was used elsewhere in routing) - is problematic. I don't recall your reasoning exactly (not that I ever got it in detail, I don't think), IIRC it was something to do with a combination of: i) ISPs didn't want to hand out topology information ii) ISPs like the kind of policies about traffic flow they can impose with destination vector architectures iii) the overhead of path computation needs to be distributed So perhaps a discussion about what you see as the shortcomings of that approach, and discussion about whether those issues are or are not handlable, would be a good thing to do here?
