[rrg] Locator Path Liveness concerns

[HeinerHummel at aol.com]

I think rerouting inside the path between multi-homed source user A  and  
multi-homed destination user B ought to be possible at which ever  point prior 
getting to B. It may be at A and at any router in the  path. It should not 
involve B nor the application being run at B. And it should  not involve the 
application at A either.
 
Rerouting may either be done such that the packets are  still forwarded 
towards the same destination location, or, if  this becomes necessary/advantageous 
(e.g. for reasons of traffic balancing),  that
the destination location is changed-  e.g somewhere in the middle of  the 
path or at/by the egress router in the first place.
 
Is this a wanted objective ? If so, any architecture, including TARA, needs  
to do something about it.
E.g. a natural approach is to convey an armed destination location as well  
the potential alternatives while a packet is transmitted. Right ?
