In short, in our model, ISPs provide Source Address Selection

The consumer edge router receives those policies (from

End nodes put them into policy table, which leads to
appropriate source address selection.

Hm, I'm worried about the policy information becoming too extensive to fit comfortably in DHCP or RA packets. I guess it would be possible to broadcast basic policy information this way and then create a cache of more specific information on-demand, e.g. when ICMP messages come in.


(The advantage of using RA here is that when connectivity changes, a lot of hosts can be informed quickly about a new policy.)

Why must the padding be ones? On many systems, newly allocated memory is filled with zeros, so this would be easier. And then there's tradition. :-)
