Selecting an Address
How do we know there is a problem?
The address went away (certain)
DPD failed (certain…but might be a transient problem)
Lack of TCP progress, ICMP, … (hmm...)

Existing protocols: SCTP, STUN/ICE
Multi6, hip, and mobike looking at this too
Probable that the solutions need to be integrated relatively closely to what is being done, e.g., SCTP or IKEv2
