[CII] One possible scenario

[John Osmon]

In periods of limited connectivity, BGP and DNS still work.
However, the outcome often looks like "the Internet is broke"
to lay persons.

Think about a situation where all the "big boys" get knocked out.  I
imagine it would look something like a situation where the small/mid
sized service providers have lost all their transit relationships, but
still have their peer relationships.

Those that rely only on transit relationships would only have internal
connectivity.  Those that had large degrees of route splay would have
a correspondingly larger view of the Internet (or what was left of it).

In such a situation, we could signal the imporatance of a given IP 
address via BGP communities.  The amalgamation of large splay 
providers could start trasiting this subset of routes, while still
only peering for "normal" traffic.  This could be dealt with via
a well-known community, and standardized among providers...

Is this an option worth looking at within this community?  Can
anyone point to similar work that we could build upon?
