Multi6 people might like to look at this and consider whether a
successful DNA solution might form part of the multihoming toolkit.
The model would be that a signal from DNA that the network attachment
had changed would be a strong hint that a multihoming event is
about to occur.

If you think any of the goals listed in the draft need to be
modified to assist multihoming, please have that discussion on
the dna mailing list, not here.

At the time a host establishes a new link-layer connection, it may or
   may not have a valid IP configuration for Internet connectivity.  The
   host may check for link change, i.e.  determine whether a link change
   has occurred, and then, based on the result, it can automatically
   decide whether its IP configuration is still valid or not.  While
   checking for link change, the host may also collect necessary
   information to initiate a new IP configuration for the case that the
   IP subnet has changed.  In this memo, this procedure is called

   Rapid attachment detection is required when a host has on-going data
   traffic.  Current DNA schemes are inadequate to support real-time
   applications.  The existing procedures for advertising network
   information incur reception delays and do not provide enough
   information to properly determine the identity of links.  For
   to-be-defined, efficient DNA schemes, a way to correctly represent a
   link change, a complete and consistent procedure for network
   information advertisement and a rapid delivery of the advertisements
   will be necessary.
