Clarify "multiple networks to choose between" #62

Open nidhijaju opened 3 weeks ago

nidhijaju commented 3 weeks ago

From Jen Linkova on the mailing list:

The charter says "The algorithm takes as input a fully-qualified domain name (FQDN), and results in a single established connection to a single server IP address on a single network. While the algorithm could apply to scenarios with multiple networks to choose between or to use simultaneously, or could deal with pools of multiple connections, such scenarios are out of scope for the working group deliverables."

IMHO " multiple networks to choose between" needs clarifying. Does multihoming, especially "multi-prefix, multi-router single-link" topology or mPVD scenario are in scope?

@furry13 would "multiple network attachments" be any better? I think the intent is to cover all of the examples you gave, in the sense that what we'd be writing down is specific to multiple attempts originating a single source IP address.

Thank you Eric, I think it's definitely more clear and specify that multi-interface multihoming is out of scope, but a single interface multihoming is I guess that would mean that something might to be said in the draft about DNS resolution - like it's performed over the same interface? or do we ignore DNS split horizon? anyway, it's another issue). I'll send a PR for this one.
