Subject: IP namespace representation / proposal
This is coming back to that discussion about IP namespace representation in the Directory some days ago. I have now finished writing the proposal which arose from Soft Pages. It describes IP address related objects in a three-level structure: 1) network non-leafs for each class-A, class-B and class-C subnetwork 2) node non-leafs for each IP address attached to a "connected device" 3) line entries for each (logical) point-to-point connection Using this method, we have modelled the backbone of the Internet within Japan and put it into our Soft Pages Directory. Thus, we are able to compare connections between our site and other sites (namely anonymous ftp servers) with respect to certain properties like estimated speed, cost etc. The proposed scheme works for that purpose very well. Currently, this Directory information still is not accessable from other sites (and not connected to _the_ Directory) but we're working to change that. If you are interested in more details, please get a copy of our paper via anonymous ftp from ftp.tohoku.ac.jp:pub/spp/ip.ps. ASCII is available as well but the figures are missing there. I'd appreciate any comments on this paper as it might/should become a draft for the Internet community. Even though the format of IP addresses might change (that class-B problem...), we certainly should make efforts to put the whole configuration info into the Directory ASAP.
