Digital Technical Journal

This journal issue provides a technical overview of Digital's networking architecture (DNA) and its evolution through four phases. It covers the following key areas:

• Digital Network Architecture (DNA) Overview: An introduction to the layers, design goals (like transparency and reliability), and the evolution of DNA, including the role of Ethernet.
• Performance and Modeling: Case studies on analyzing and optimizing network performance at various layers, from physical layer adapter placement to application layer protocols.
• DECnet/SNA Gateway: A detailed look at how Digital bridged its proprietary network architecture (DNA) with IBM's SNA environment.
• Extended LAN Architecture and LANBridge 100: Discussion on bridging technologies to extend Ethernet capabilities, manage traffic, and ensure scalability.
• Terminal Servers and LAT: A description of the Local Area Transport (LAT) protocol developed for terminal servers to provide flexible, cost-effective terminal-to-host connections.
• DECnet-VAX and DECnet-ULTRIX: Technical papers detailing how DNA was integrated into the VAX/VMS and ULTRIX operating systems.
• DECnet-DOS: An overview of implementing network services on the MS-DOS platform.
• Network Management: Articles on the evolution of network management, including the NMCC/DECnet Monitor and the transition towards integrated, intelligent, and distributed network management.
