Hence, if that argument is valid against host based solutions, then we are completely out of luck. Yours, Joel Strategy A: LISP-ALT may be viewed as some outsourcing trick - however staying inside the same inertial frame. Strategy B: Appears to be out of luck - see above. Strategy C: Besides overcoming the scalability problem and making Moore's law applicable to routing etc., it would also enable multihoming where both network and/or end users may impose path changes such that different egress routers from different ISPs are passed. Multihoming can be considered as a special kind of ANYCAST whereby it makes sense to change the anycast dest. node within the IP packet flow and also a single packet's anycast destination node in the middle of the path (because each of these anycast destination nodes would deliver it to the same end user). Network reasons like traffic jam or temporary drop outs may cause detours and a detour might be such that a different anycast dest. node becomes more suitable to go for. Yes, these are not ECMP alternative paths but genuine detours which to offer/handle would be part of strategy C as well. Heiner
