Well, I fully support the idea of a new layer above the transport with new names and whatever names resolution system requires. I think that because the idea is hanging in the air during so long time and being researched by academy during number of years, there is definitely a need for a new

Regarding (a) and (b) alternatives it would be nice to have both. However it is not clear why multihoming for v6 and v4 are different issues. Handling of multiple addresses per host is the stack design issue. The major problem is not to choose the right interface and to send data through it.

(regarding the complexity of putting a general-purpose layer to survive address changes between L4 and L7) But why do you assert that it will take lots of complexity and overhead? Can you point to some code where they tried this? As far as I know, nobody has really given this an earnest

Regarding this discussion about an indirection layer, I am thinking we really should propose the formation of some forum for discussion of these issues. [...] Call it an indirection layer or a stabilisation layer or whatever you want, but we need a forum where we can specify the problem we

Keith; (regarding the complexity of putting a general-purpose layer to survive address changes between L4 and L7) It is not merely complex but also useless to have such a layer. The basic problem of the approach to have such a layer is that only the application layer has proper knowledge on

well, the reason I named a specific time interval was to provoke discussion, so I suppose I shouldn't be disappointed... I am not sure that one week is the best figure. I imagine that figure could reasonably be picked to be anywhere between several hours on the low end to a few weeks on the high

It's not uncommon to see a FQDN point to several IP addresses so that the service identified by the FQDN can be provided either by (a) multiple hosts, or (b) a host with multiple addresses. Now if we want to support moving from one addresses to another in the middle of an (application
