Re: [RRG] Six/One: A (Different) Solution for Routing and Addressing in IPv6




Hi Christian,

Thanks very much, yes, that's much clearer.

Since hosts adopt a new IP address after a rewrite, network-enforced
provider changes (i.e., path changes) are visible to both hosts of a
connection.  Hosts can then do whatever is necessary to adapt to the
path change efficiently (e.g., by resetting TCP RTT estimations and
triggering Slow Start mode).

I'm not clear on this. Specifically, are all policy selections truly visible
to both sides?  Suppose host A selects provider 1, only to be
overridden by his administration to use provider 2.  However,
correspondent host B exercises its prerogative and sends the packet
to destination provider 3.  When A receives the packet, it has no
idea that provider 2 was ever involved...
