Metropolitan Area Network - On Sun, 4 Jan 2004, Ronda Hauben wrote: Are you saying that the ARPANET is the same as the IMP subnetwork of the ARPANET? The whole point of the IMP subnetwork is to connect diverse computers and diverse operating systems. The ARPANET is the connection of these diverse computers and operating systems. It isn't the IMP subnetwork. The IMP subnetwork is the means of connecting the diverse computers, but is *not* the ARPANET.Ronda, were you a user of the ARPAnet in its halcyon days (1970-1982)?I was. I implemented the first 96-bit leader (32-bit address) ARPAnetNCP for the PDP-10 in 1978. I was very much part of the TCP/IPtransition in 1983, and the subsequent ARPAnet/Milnet split. I wrotesome of the earliest implementations of Telnet and SMTP. I even wrotean EGP.I have never heard the term "IMP subnetwork" used. Nor have I everheard of this strange case which you seem to be making.The notion that the wires of an LH or DH connection are part of a"network" is rather, uh, strange to anyone who actually dealt with iton an electrical basis. A better case may be made for a VDHinterface, but that in turn was more of a point-to-point network.So is the notion that the hosts on the ARPAnet were part of thenetwork. It's akin to saying that a human user of a telephone is"part of the telephone network."The notion that the only important difference between ARPAnet andInternet is that "Internet made it possible to connect differentnetworks, not just different computers" is laughable to anyone who wasactually there.In conclusion, I will echo John Levine: These facts are well known and easily checked by anyone who cares to do so, and you only make yourself look foolish by trying to argue that the situation was and is otherwise. I have no interest in arguing about facts, so this is my last message on this topic.-- Mark --http://staff.washington.edu/mrcScience does not emerge from voting, party politics, or public debate.Si vis pacem, para bellum.
