[mat-wg] some thoughts on add-path and bmp at ripe/ris

alessandro,

real data and experience deeply appreciated.  a few questions.

  o once a collector commits to ADD-PATH, it's a promise to keep
    the data forever; well, it's been 26 years of RV and a few
    less for RIS.

    - Did operators find the ADD-PATH data sufficiently useful
      to be worth the cost?  How did they use the ADD-PATH data
      and how often?

    - Did researchers find the ADD-PATH data sufficiently useful
      to be worth the cost?  How did they use the ADD-PATH data
      and how often?

    - Did folk develop special tools to take advantage of
      ADD-PATH data?

  o On the problem of stream/peer identification.  You describe
    the divergence of BIRD and FRR.  What about commercial
    router vendors?

  o You say data were often redundant, though not fully.  Did
    you investigate mechanisms to reduce the storage, or did you
    see that as a path to complexity and fragility merely to
    save some spinning rust?

  o You mention the withdraw storm between your peer and their
    peer (and later an announcment storm, I presume).  For peers
    with large out-degree, this could be likely.  Were these
    data interesting in any way, or just more storage?

again, thanks so much for real experience.  gives me a bit more
clue.
