I don't understand this clearly. IPv4 isn't "legacy" and won't be until after most of the world's billion or so Internet users and their ISPs have been convinced to change over to IPv6, which for a long time will be a network where only a subset of other hosts can be reached on. Even if IPv4 applications are in the minority, and still need to run, I don't understand your reference to 14 million /24 prefixes. >> Multihoming 10%, 50% or probably anything less than 95% of traffic >> does not strike me as useful. > > Hm, I'd rather redownload 5 out of 10 files when my ISP craps out than > 10 out of 10. Partial deployment for multihoming is still useful. Yes, but I would say that for any substantial organisation, running servers or having a bunch of desktop users or both, that they are not going to invest in some new technology, more complexity, new addressing arrangements perhaps and a second ISP if the new multihoming scheme is only going to work for half their traffic. I think they would need a much higher figure - such as 90%, 99% or something like - this before the multihoming could be regarded as substantial enough to justify the investment. >> Until that level is reached, there are only costs and risks in >> installing the new system.

Yes, but Ivip with its OITRDs (Open ITRs in the DFZ) and LISP with its PTRs (Proxy Tunnel Routers) can provide multihoming for 100% of traffic, no matter how few other networks are upgraded. - Robin _______________________________________________ rrg mailing list [email protected] https://www.irtf.org/mailman/listinfo/rrg
