Hi, Tony, I have two problems in communication:
o I'm in fact not a routing expert, even without any field experience. I'm just a teacher, so that I have to know clearer to teach my students in the right direction. o Over more than 40 years, English is still my foreign language so that I sometimes have a problem in extracting the full meaning/implication out of beautiful/concise wordings. And so, please be patient with me a little bit more, and let me give you an ensuing question below.

This allows us to migrate to a PA based addressing > architecture. Suppose the same situation in the current Internet that a site is multi-homed. So, for example, my site has got two sets of PA addresses from two ISPs. Then each host in my site would have two IP addresses. Then, think about any host transitioning across these two addresses. Is there any other problem with this activity than the one you described above in terms of ILNP? To me, it looks quite equivalent. My host will know of the two in existence, and will switch between the two as need arises. I assume we're talking about multi-homing, not mobility here specifically in this context. If it's about mobility, I can see that ILNP has an advantage for TCP connection is not associated with locator while it would be with the current IP address. But as long as you were talking about multi-homing, you would not mean fast transitioning without breaking a TCP connection. You would implicitly mean a situation where the same host would be associated with a connection at one point in time and with another at a different point in time. Or even with two simultaneous yet separate connections. In all these connection scenarios, I would assume that the effect would be the same in both cases of ILNP and the current Internet. I must be missing a critical point here. But, if I'm not, wouldn't it the description of yours apply in the same way to the current Internet? The same situation with multiple PA addresses? Remember, in my scenario, I'm not using PI addresses. Help me out, please. > > Tony > > > _______________________________________________ > rrg mailing list > [email protected] > http://www.irtf.org/mailman/listinfo/rrg > -- DY _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
