Noel, Network layer is the matter of the network. The fact that there exist IETF activities which want to handle network congestions by informing the sending hosts doesn't prove that hosts are the right peers of the network layer. The network is a shared resource. A host however can only act in egoistic manner. And there are many more issues which are not the business of the user. Multihoming: Ok, the user should have the capability to express his preferences. But it is not only up to him. I cannot understand that there is a debate like this. Heiner

So it seems reasonable to me to accept this and start by optimizing for this case and move to the hosts over time. -Darrel _______________________________________________ rrg mailing list rrg@irtf.org http://www.irtf.org/mailman/listinfo/rrg -----Ursprüngliche Mitteilung----- Von: Darrel Lewis (darlewis) <darle...@cisco.com> An: Noel Chiappa <j...@mercury.lcs.mit.edu>; rrg@irtf.org Verschickt: Mi., 2.

Noel, I'd note that (most?) of the host based schemes for loc-id split seem to dd network middle boxes to aid in their initial deployment (hip-proxy, him6-proxy, et al).
