Bill, I see most of my comments all over the years addressed by strategy B, however please specify what you mean by "perform plain old hierarchical aggregation on the LOCs". I am afraid you mean Nimrod/PNNI topology aggregation to which I formerly looked up with glee - but not anymore. During the last time I praised Google-map, e.g. how a route from NY,Broadway, to Sausolito, Main-Street, is drawn "across differently zoomed maps". But meanwhile I see that Google-map cannot catch-up with TARA either: If you see the blue line passing the entire US and you want to zoom closer, let's say at some place half-way down, like Chicago, it cannot be done :-( Routing technology could need some big push everywhere :-) Heiner In einer eMail vom 11.11.2008 21:39:36 Westeuropäische Normalzeit schreibt [EMAIL PROTECTED]:
Hi Folks, I'm trying to put together a more or less concise summary of the general architectures we've discussed here these past couple years. This is not a comparison of specific proposals (which Robin Whittle has done an excellent job of) but rather a summary of the universe of general strategies we've looked at and haven't resolutely rejected. I'd appreciate your constructive criticism: http://bill.herrin.us/network/rrgarchitectures.html Particular answers I'm interested in: 1. Have I overlooked any viable approaches to the problem? If so, what are they? 2. Have I overlooked any architectural elements? I'm looking for architectural elements here, not engineering issues. For example, I left out path-MTU issues because that's a "how do we shoehorn this into IPv4 of IPv6" engineering issue. It's only relevant in an engineering compatibility context. Obviously engineering compatibility issues will greatly inform the final architecture, but that's not what I'm after in this document. 3. Do you see any areas where I could offer a more clear description? How would you word it? 4. Have I listed anything for which we have a strong consensus that we can discard the approach from consideration due to some uncorrectable defect which is obvious even without an engineering viability study? By strong consensus, I mean "nearly unanimous." Thanks in advance, Bill Herrin -- William D. Herrin ................ [EMAIL PROTECTED] [EMAIL PROTECTED] 3005 Crane Dr. ......................
