Introduction to Minicomputer Networks

This document, published by the Digital Equipment Corporation in 1974, acts as a technical handbook for designing and implementing minicomputer networks. Key topics covered include:

• Network Foundations: The evolution from timesharing to distributed minicomputer networks, including the benefits of resource sharing.
• Topologies & Switching: Analysis of various network layouts (star, hierarchical, ring, distributed) and switching techniques (circuit, message, and packet switching).
• Network Functions: Detailed roles of components such as host processors, front-end communication processors, and remote concentrators.
• Hardware & Software: Building blocks including modems, interfaces, and operating systems (COMTEX, RSX-11M, RSX-11D, RSTS/E, and RT-11).
• Communication Protocols: In-depth examination of line control procedures, including BSC, DDCMP, and SDLC.
• Practical Implementations: Case studies for industrial, laboratory, reservation, and credit card verification environments.
