I have some questions. This might be better suited to another
group (is there one dedicated to arpa/internet access besides
this one?), but here goes.
What is the cost of having access to the net (via your
own machine)?
Somewhere on campus here, we had a Post script formatted
map of the network (showing who is on .mil, and who is on .com
etc etc)...does anyone know where I can find this?
thanks
John

It depends mostly on how close the nearest access point is to your computer and what kind of computer you have and what you purpose for connection is and and how much bandwitdh to the net you would like. Maybe a couple of examples might clarify. Ex. 1 Your network connection is a local machine across the room. Just string some ethernet cable across the room. Get the SysAdm to assign you a spare internet number and zoom! You are on the net. Ex. 2 You don't have a campus connection and want a 56k baud connection. Start with about 25k in equipment costs, add line connect charges, annual rental of line (say 40 miles), add private network gateway cost you should end up with 30k startup plus 20k recurring. This IS just an example, your milage my vary.

Not particularly germane to your question, but this sounds like an interesting map. How is the "class" of the user related to the network to which it is connected? Upon which network would I find *.gov, *.mil, *.com, *.edu, *.de, *.au, *.nz, etc.? How was this determined? As a discrete example, on which network would you find "contel.com"? (A hint--name all network(s) to which contel.com is a member--*.gov, *.mil, *.com, etc. doesn't suggest anything accept the "class" of activity in which the organization is involved.) Merton

well, there was a horizontal line and off from that broke the basic networks (.com .mil .gov etc) in vertical directions (some up, some down). Each "T" in the network was a further sub net (so, when the .edu broke off the base line, there were further breakoffs to .gatech and .mit and .berkeley etc) I think they put commercial orgs on .com even if they had an additional .mil address.. it wasn't meant to be a geographic map (from what I saw) but a network topology map. hope that explains it..if I find a copy, I'll send it to you.

John: I like your statements--they follow the party line. Let me insert a little reality before you send any maps--actually send the maps, I would like to take a look at this make believe world. The point of my interest was that the networks never devolved in the conceptual outlines that were anticipated years earlier. There is no *.org, *.gov, *.edu, or *.com networks. There is an *.mil network but it incorporates all of the preceding "classes" of users. There are regional networks that incorporate these "classes" of users. There are no networks, to my knowledge, that are composed of a single "class" of user. For example, *.contel.com is a member of several networks. The membership is partly historical, it is partly a matter of emphasis, and it is partly a matter of entry and sponsorship in the ARPA and MILNET domains. Actually, one might want to consider the role of acquisition in network membership. The domain *.imsd.contel.com is a MILNET member, all other *.contel.com domains are members of SURAnet. Another example is the *.radc.af.mil domain. The tops20.radc.af.mil system is part of NYSERnet. The lonex.radc.af.mil and subsidiary systems are strictly a part of MILNET. One can access the *.radc.af.mil domain either through NYSERnet or MILNET. Merton

My understanding on this issue (such as it is :-) ) is that the name space is independent from the actual network topology. E.g., having an "edu" domain does _NOT_ mean that one should expect to find an education net. If this thread goes much further, it would probably be more appropriate for name-droppers.

I guess what I wanted to say, is that the map that John is referring to is a map of the Domains of the internet. I remember seeing it once, and it is strictly a break-out of all the domains registered with the SRI-NIC... I don't know that that means you can get it from the NIC, however. I am sure that I did not get it from the NIC myself. I also remember that I got this "map" early this year, and it hadn't been revised since 88. If anyone does run across a really current one, I'd be interested in seeing how well it reflects our af.mil reality (:-> /matt jonson@server.af.mil I speak not for my organization.

Sorry if my statements were misleading. I know that the *.mil and *.edu\ don't denote a PHYSICAL network.. but a "logical" network.. The map is drawn along this "logical" network. I understood this, but I guess that didn't come across.. sorry. John -- Emporers Thought for the Day: | John E. Rudd jr.
