Implementation of the Intelligent Gateway Processor Using UNIX

摘要

The Technology Information Systems (TIS) Program at Lawrence Livermore National Laboratory, jointly sponsored by several government agencies, has implemented a new approach to systems interconnection and user interfaces. The ''Intelligent Gateway Processor'' (IGP) is an integrated package designed to provide a single user interface to a variety of systems, automate access to information resources, and provide audit logging and authorization controls. The IGP software is UNIX-based, but the IGP approach is applicable to any heterogeneous environment. This paper discusses the implementation of the IGP software: why UNIX was chosen (and retained); the role of the individual IGP modules; how they were written to fit into (and improve on) the UNIX concept; and plans for the future of the IGP concept. 9 refs.
