David can speak for himself, but speaking on my own behalf as a implementer: if we define a canonical order, comparing two PDUs is a simple binary string comparison. If we don't define a canonical order, comparison is more complicated, hence more error-prone. Given that the rpki-rtr protocol requires duplicate elimination, we do need to perform such comparisons, so making them as simple as possible seems advisable. FWIW, I think David's suggestion is a good one, and I'm likely to implement it that way in my server whether required to do so or not. _______________________________________________ sidr mailing list [email protected] https://www.ietf.org/mailman/listinfo/sidr
