Christian, you are absolutely right. However, avoiding any impact on the users has been the number ONE objective of LISP. And now, by moving even to LISP-DDT,i.e. dumping allegeable worse variants, the consequences will be disasterous. Heiner

I think that we are giving up too early on the feasibility of updating all hosts. Indeed, any substantial change in routing and addressing would most probably end up changing all hosts, or at least most of them. I also think that a research group should not necessarily shy away from investigations that affect all hosts. If research comes out with a brilliant shiny star on the horizon, then engineering might follow. If the best we can do is hack on the edges of current solutions, then engineering groups can definitely do that, no need for a research group. -- Christian Huitema _______________________________________________ rrg mailing list rrg@irtf.org http://www.irtf.org/mailman/listinfo/rrg
