So the first packet must be dropped. Well, is that latter really necessary? I know it's more complex to hold onto the packet until the mapping comes back, but if dropping that first packet causes problems, we could write that code without changing anything else in the system; i.e. it's an optimization we can add later, invisibly to the rest of the system, if it turns out we need it. > If there is some place packets for destinations that aren't mapped yet > can be sent to so they arrive anyway, even if this path is slower, this > takes a lot of pressure off of the encapsulation devices, Interesting idea. Let me ponder that... > The issue of determining rendezvous locations .. is simple enough: have > each rendezvous point handle a very long prefix, such as 96/6. How about piggybacking the user's data packet on the request for the EID->RLOC binding? When the request gets to whereever that binding is available, it's sent on to the ETR, while the mapping is sent back to the requestor? That avoids all the extra mechanism/configuration of rendezvous points. Noel _______________________________________________ RAM mailing list RAM@iab.org https://www1.ietf.org/mailman/listinfo/ram
