The German part would be interested; however, a couple of "incompatibilities"
between our local map and the rest of the world, which would have to be
addressed first and I would like some input as to how others have solved
these problems.
1- Since our maps currently are totally independent, a few duplicate names
have crept in.
Solution? Kick these guys out of our maps? Maintain two maps, one
(external) with the duplicates removed?
2- There exist some links between sites in "our" map and sites in the
"official" German map. Some of these cost real money and should either be
marked terminal or deleted from the global maps. This also tends to
indicate a necessity to split the maps into inter- and intra-network parts.
3- The official German maps consist mostly of entries marked HOURLY.
That tends to warp the routing decisions. :-(
This problem is aggravated by item 2, above.
In other countries, it's even worse; in France, for instance, all links
from inria.fr to other French sites are HOURLY, but there's no registered
back link -- pathalias considers these to be DEAD.
In the interest of avoiding flame wars about how to resolve these problems
and incompatibilities, please mail comments to me; I'll summarize.

Not on our side. We maintain stricly "UUCPMAP" conforming maps, with one extra file (u.mug.0) to define the gateways to other nets. This file can be skipped when a full set of maps is used, like I myself do. > 1- Since our maps currently are totally independent, a few duplicate names > have crept in. > Solution?

Matthias, I suggested this before: create an extra "gateways and other garbage" map file, which is ONLY to be used from within SubNetz. All other networks (like mine :-) can then skip that file... > 2- There exist some links between sites in "our" map and sites in the > "official" German map.

Yes, same here. Just define them DEAD. Since DEAD is always less expensive than not-at-all (i.e. for the SubNetz-only maps), that route will be followed anyway from people within SubNetz. We do the same trick here with some sites (can't tell their names because of bloody EUnet policies).. > 3- The official German maps consist mostly of entries marked HOURLY. > That tends to warp the routing decisions. :-( > This problem is aggravated by item 2, above. > In other countries, it's even worse; in France, for instance, all links > from inria.fr to other French sites are HOURLY, but there's no registered > back link -- pathalias considers these to be DEAD. The French maps are a bad joke, we all know that. However, some people ARE working on that now... > In the interest of avoiding flame wars about how to resolve these problems > and incompatibilities, please mail comments to me; I'll summarize. I did that, but posted it as well for general interest. Besides, people asked me to do so...
