Design of a Local Computer Network for the Air Force Institute of Technology Digital Engineering Laboratory

摘要

A local computer for the Air Force Institute of Technology Digital Engineering Laboratory was designed and the network command language interpreter modules were implemented. The requirements for this network were specified by interviewing nine faculty members associated with the Digital Engineering Laboratory and then translating their functional requirements into a detailed set of hardware and software system requirements. Structured Analysis was used to produce a structured specification for the applications, host-to-host, network, and link protocol requirements. Yourdon and Constantine's Transform Analysis and Transaction Analysis techniques were then used to develop a set of module structure charts for the software design. The network uses a loop topology for the software design. The network uses a loop topology for the nodes with a star of up to four hosts connected to each node. The nodes are implemented using a Universal Network Interface Device (UNID) developed at the Air Force Institute of Technology. Initially, the network will include an Intel Series II Microcomputer Development Station, a Digital Equipment Corporation VAX-11/780, and a Data General Nova.
