You and others keep asserting that a pull-based mapping distribution model is a "non-starter" because it "won't work". I've been trying to get from folks _concrete_ examples of applications that "won't work" in the face of increased latencies on the order of 10s or 100s of milliseconds after a cache miss. In response I get vague handwaving about voice or video (I know from personal experience that UDP-based NFS works fine in the face of an initial packet delay of 10s of milliseconds) or descriptions about classes of applications that would appear to be degenerate cases and asymmetric routing that would likely have unpredictable performance characteristics with pull or push. > >GIven the lack of data, it would seem we've descended to the realm of religion, so I'll give it a rest. Sorry, but I misunderstood you to be asking for what class of applications have this problem, and my reply was intended to answer that: those which do codec negotiation based on observed rate. Another class is those that use race conditions to select flow endpoints (e.g. anything that will use ICE). Not too many things use ICE yet (still not standardized), but there are plenty in the former category. Are you looking for something that has source code available, so you can see what changes it would take to adjust the paradigm, or ubiquity, or what?
