Hi Tony,
5) Section 7 of http://www.cs.berkeley.edu/~zmao/Papers/sig02.pdf 'Selective Route Flap Damping' makes some really interesting proposals that sound promising. There is some similarity with my point 3 above, and it contains some potential alluding to the long forgotten transitive attribute DPA that never got off the ground. I particularly like i) Only treat withdraws as bad events and ii) wait until the next announce before triggering further penalties. For the authors, would these alterations alone to the damping spec have a large positive affect on the overall stabiulity of BGP systems ?
To answer your question, I believe this proposal would reduce the likelihood of suppressing routes due to a single originating withdrawal. However, from the BGP Beacon experiments we are conducting, (where we have controlled originating withdrawal and announcement) we have also observed that a single withdrawal has caused alternating announcement and withdrawal messages. We plan to quantify the impact of this proposal, once we obtain more data. Thanks. --Morley
