References: Does anyone have any information on the Lawrence Livermore Lab Intelligent Gateway Processor (IGP) project? I have an abstract called "Gateway Technology as a Tool for Interoperability in the DAITC Information Network" and I'd like to get more information on this. Thanks. ps: when I was a kid we called it the "rad-lab"! I guess LLNL sounds better... -brad Brad Parker Cayman Systems harvard!cayman!brad -- Brad Parker Cayman Systems "Mama's little baby likes violent sex..." harvard!cayman!brad - from a song I heard on the radio.

Brad, The Intelligent Gateway Processor is a generic term for software originally developed at LLNL, and now commercially marketed by Control Data Corporation's Professional Services Division as ASCENT. The software comprising this system was developed as a generic front-end to heterogeneous systems for scientists at the Lab. It consists of two major pieces of software, the Network Access Machine, and a menu- oriented user interface. Without going into a great deal of detail, NAM uses an interpretive language to initiate and manage "connections" over a wide variety of "communication methods": direct RS-232, TCP/IP networks, X.25, dial-up phones, etc. This software strictly resides on a UNIX (or perversion thereof) host, and requires no additional hardware or software on the attached hosts. Basically, the software is used to insulate users from the complexities of various network configurations, intermediate devices (dataswitches, network interface units for broadband LANs, protocol converts, etc) and connection procedures in large, heterogeneous computing environments. Additionally, it has the capability for handling portions of, or entire, sessions with a host on behalf of a user. In a current commercial implementation, we use this technology to support connections to DEC VAXES, CDC Cybers, NAS 5000 & 7000s, and Data General Workcenters over TCP/IP and X.25 networks from users coming into the IGP via dial-up, DDN telnet, broadband LANS, and Fiber-Optic muxes. The IGP is being used currently by various DoD agencies, mostly the Air Force, Department of Energy, and the Defense Logistics Agency, among others. Over the past several years there have been several papers published or presented concerning this technology. Although I don't have my copies here at home, I'd be happy to supply a list of references to them and where you can get copies if interested. I just recently (Friday) completed the latest such paper (which is why I'm finally getting to my EM now) entitled "Connectivity and Beyond." I feel (somewhat biased naturally) this paper gives a good overview of the reasons for this technology, and how it works in heterogeneous environments. As soon as it has complete being cleared for public dissemination (since it references a military project), I will be happy to provide copies of it. Barry D.

Non-commercial inquiries should probably be addressed to the Technology Information Systems (TIS) Program at LLNL. I don't know the specific person to contact, but a message to postmaster@lll-tis.arpa or root@lll-tis.arpa will probably get you some information.
