Gensym Corp, Cambridge, Massachusetts developer of the G2 Real Time Expert System, has announced and demonstrated G2 Network, claiming it to be the first architecture to support co-operating expert systems for distributed applications. G2 Network is written for standard computer networks, enabling users to create expert systems that co-operate in real time. It was demonstrated using a TCP/IP Ethernet link between G2s running on computers from Sun Microsystems, Hewlett-Packard and Texas Instruments, and also on a DECnet connection between DEC VAXstations. G2 Network consists of four elements: G2 Real-Time Expert Systems; Intelligent Communications Protocol – ICP – networking software, Telewindows remote window system, and the G2 Standard Interface interface development package. The key addition, the Intelligent Communications Protocol, is a network protocol layer enabling knowledge-based applications to share information across a network of co-operating applications, data servers, user interfaces, and support software. It runs on top of the likes of Ethernet, DECnet, TCP/IP, and other Open nets. Telewindows enables access to any number of G2 real-time expert systems in a network with multi-user access to a knowledge base; no prices or delivery given.
