In the particular fcc MBA context, a concrete example is to change the
subscriber tier (end point property). But since you mentioned map, I
guess you are saying e2e (e.g., more narrowly bounded app flow).
[RP] hummm…Not necessarily e2e. If I write to a map and change the cost
of reaching the IP address associated with my application, I need to
be put in a different PID. I believe the same is true for endpoint
properties if you want to actually influence the cost map.
Reinaldo: Interesting ... you are proposing an alto.put() mutator,
whereas what we have now is mostly alto.get() accessors.
Once we do this, we are perilously close to sdn/i2rs type of thinking
(I think). However, if I understand you correctly, you are advocating
a bounded alto.put() functionality ... perhaps an endpoint migrating to
a different PID. I don't think you are advocating a wholesale
application-specified state insertion into the network.
The use of ALTO in scenarios that require changing the basic networking
plumbing has been discussed in academic papers, at least (at the cost of
a self reference, see [1]). There has been some discussion in the ALTO
mailing list of such functionality as well, but to date my impression
is that such discussion has been limited due to the overlap between
sdn/i2rs type of work.
