Re: [mif] Happy Eyeballs Extension for MIF

Hi,

This is interesting work. Couple of questions:

Is the value of I initially zero for any destination/hostname that has not yet been connected to?

draft-ietf-mif-dhcpv6-route-option and RFC4191 allow definition of specific routes. In the presence of specific routes it sounds, for me at least, somewhat odd to send connection attempts via all interfaces. What about incrementing I for a destination address that matches a more specific route? Hence initial connection attempt would be sent over the interface that has matching route and other interfaces would be tried only if no reply on the preferred one?

How does the value of I relate to time? (i.e. if I is -1 does the node wait 10ms before trying corresponding less-preferred interface).

Why would the DNS query be sent over all interfaces? Is it because "I" for a destination name is initially a zero? Like in routing case, if Improved DNS Server Selection is in play, would the "I" be nonzero for those interfaces over which DNS suffix matching the requested name has been received on?

Best regards,

	Teemu
