This thesis discusses the design issues and fundamental
techniques of a Local Area Network ( LAN) , designs and
chooses a LAN for the military. The three HQs and DoD of
Korea operate their own computer center with no connection
among them. All the exchange of data is performed manually
and slowly. But, they want to rapidly and accurately
exchange information among the fields of logistics,
intelligence and operations.
First, this thesis represents the overview of current
system; how the system is organized, how it functions and
what its existing facilities are. The thesis introduces the
system objectives; the improvement of combat readiness and
office automation. The overview and objectives of the system
are utilized as a basis for system analysis. Through the
system analysis phase, user's requirements are identified;
information production, information transmission and information
management. Based on user's requirements, LAN
requirements are identified; software, informations transmitted
on the network, security, reliability, interconnection
and interfacing. Through requirement analysis, the
evaluation criteria for a LAN design are produced and a
model of system is explained by using Data Flow Diagram
(DFD) and Data Dictionary (DD).
Additionally, the thesis examines the issues for
designing a LAN and goes on to select four fundamental technical
ingredients. These are (1) access control method, (2)
transmission media, (3) topology and (4) transmission techniques.
Finally, the thesis selects and recommends a
military LAN; a single-cable, midsplit broadband system.
