The UUCP map is posted to newsgroup mod.map.uucp every month. This posting is being tried in June, and if it works out it will happen every month. The posting is staggered over the entire month to keep from flooding the net with 840K all at once. There are a total of 8 bundles; the first two are the single files att.nj and att.il, then the a's (asia, att, aus), Canada+Europe, and four alphabetically grouped USA bundles. Bundle sizes range from 88K to 138K. The map is also available on a demand basis at a number of hosts who have volunteered to make their copy available to the general public ; details of this access are posted separately to mod.uucp.map. The current map totals about 840K bytes. The largest file, att.nj, is about 112K, other large files are att.il (88K), usa.ca.n (80K), usa.ca.s (46K), usa.ma (35K), and can.on (31K). The largest bundle, Europe+Canada, is about 138K. The files are organized by region, where the regions are currently asia, aus, can. eur, usa, and att. (AT&T gets its own region because it accounts for nearly half of the map, and has its distribution organized internally.) This map can be used to generate mail routes with pathalias. Pathalias was posted to Usenet in January 1985 and will be posted again as need warrants. The map is also useful to determine the person to contact when a problem arises, and to find someone for a new site to connect to. Please check the entry for your host (and any neighbors for whom you know the information and have the time) for correctness and completeness. Please send corrections and additional information to uucpmap@cbosgd.UUCP or cbosgd!uucpmap or cbosgd!uucpmap@Berkeley-ARPA. This map is maintained by a group of volunteers, making up part of the UUCP Project. These people devote many hours of their own time to helping out the UUCP community by keeping this map up to date. The volunteers are: Rick Adams northeast Gordon Moffett north Bill Blue scal Greg Fowler ncal Rick Kiessig pacific Doug McCallum mountain Piet Beertema europe Bill Welch southeast Mike Schuh midwest Gary Murakami att The remainder of this file describes the format of the UUCP map data. It was last updated 6/1/85. Each host has an entry in the following format. The entry should begin with the #N line, end with a blank line, and not contain any other blank lines, since there are ed scripts that do /^#N $1/;/^$/p #N name of host #S system type #O organization #C contact person #E contact person's electronic address #T contact person's telephone number #P organization's address #L latitude and longitude #R remarks #U netnews neighbors #W who last edited the entry and when # name="name.domain" sitename connection(FREQUENCY), connection(FREQUENCY), connection(FREQUENCY) The formats for most of the lines above are not critical, but note that each line must begin with #, the key letter, a tab, and then the information. See any entry in the map for examples. The word "city" in the #L entry means that the lat/long given are for the city listed in #P, not precisely for the building containing the host. This information is intended to be used for machine generated maps, so the format of #L is important. The name="name.domain" entry should be given only if the host is a member of a domain other than the top level name.UUCP, which is assumed. Leave off a trailing ".UUCP", if present. Thus, the host cbosgd.ATT.UUCP woudl give name="cbosgd.att", a host Berkeley.UC.EDU would give ucbvax="berkeley.uc.edu", and a host xyzvax.UUCP would leave out this line. Currently very few domains are formed and even fewer are registered. The lines not beginning with # are to be interpreted by the pathalias program so their format is important. The reader is referred to the documentation for pathalias for details. Briefly, the host name (the UUCP 6 letter name, not the dotted domain name) is listed, along with the list of other hosts that the host has a direct connection to, and the cost of the link. This cost can be roughly thought of as the time to get mail from the local host to the neighbor. (This cost may be very different from the cost going in the other direction.) Pathalias looks at all the links on the network and their costs and finds a least cost path from the local host to all other hosts on the net. The different connection frequencies and implied connection costs are as follows: LOCAL 25 DEDICATED 95 ARPA 100 DIRECT 200 DEMAND 300 HOURLY 500 EVENING 1800 DAILY 5000 WEEKLY 30000 DEAD INF/2 There are a few other cost names that sometimes appear in the map; these are discouraged. Some are synonyms for the prefered names above (e.g. POLLED means DAILY), some are obsolete (e.g. the letters A through F, which are letter grades for connections.) It is not acceptable to make up new names or spellings. Arithmetic on these values is permitted, thus DEMAND+LOW adds a slight penalty to DEMAND to break ties in favor of some other link, while DAILY/3 means the cost is one third of a day (e.g. the hosts talk about three times per day,) and DAILY*3 means it takes three days to get mail over the link. !Funky!Stuff!
