From: Ron Tencati <TENCATI@JPL-VLSI.ARPA> Hello again, As Christmastime approaches, I find it that it is time for my monthly network inquiry. This month's topic is GATEWAYS. I am trying to come up with some kind of scheme whereby I could network together some computers here at JPL via some kind of Local Area Net, and then gateway those computers to the ARPANET. Currently, there is a broadband Ungermann/Bass LAN installed at the Lab. One method would be to net some machines together on this LAN, and put one of them onto the ARPANET to act as the gateway. Another idea is to implement some other kind of network for the LAN, and then do the gateway. I am seeking information (general and technical) from persons who have implemented LANs with ARPA gateways at their facilities. In general, I'm interested in types of configurations that are being used, and your experiences with them. I would also appreciate getting a feel for how traffic affects the gateways, as well as a feel for an implementation estimate with respect to manpower, software, time, and resources that were needed to implement your particular configuration. Our initial configuration will probably be all VAXes, but we would like to plan a LAN/GATEWAY that is flexible enough to support many different CPUs on the same LAN. If you'd rather not clog up the mailing list with replies, feel free to send them direct to me. Thank you for any help/info/assistance anyone can send my way. Ron Tencati JPL-VLSI.ARPA Tech.
