Re: [Add] draft-arkko-abcd-distributed-resolver-selection

[Adam Roach <[e-mail]>]

Not relating to the question at hand as much as the contents -- it's 
probably useful in any treatment of this topic to include a discussion 
of how to handle additional records. E.g., if the query distribution 
algorithm would ordinarily query server A for record X, but has already 
received record X as additional information from server B, what behavior 
would we recommend?

(A simple analysis would say to use the already-received information, 
since it minimizes transmission of queries altogether.)
