OSI Model Layering of a Military Local Network

Article Abstract:

A new local area network (LAN) is organized in accordance with the ISO Open Systems Interconnection (OSI) Reference Model. The LAN provides flexibility of signal interconnection between various resource devices that form a node of the communications system. The diverse signals require a circuit- switched service and can take advantage of the benefits provided by the standards. The seven Reference Model layers are used to decompose the LAN into seven primary modules using structured analysis techniques. Local system operation of the LAN is validated by stacking the layers up and following a represenative sampling through setup and operation. Diagrams illustrate LAN layering and layer interaction.

The OSI Network Layer: Standards to Cope with the Real World

Article Abstract:

The Open Systems Interconnection (OSI) Network Layer provides end-to-end communications capability to the Transport layer entities above it. The Connection-Oriented Network Service uses Network Connections to provide communications capabilities. The Connectionless Network Service transfers units of data without a Network Connection. The Network Layer is more complex than other layers of the OSI model because it contains components which are outside of end systems as well as functions in subnetworks. Tables and diagrams illustrate architecture and parameters of the Network Layer.

On Determining a Computable Ordering of a Digital Network

Article Abstract:

Determining a computable ordering of a digital network is the same as topologically sorting the nodes of an acyclic directed graph. Topological sorting can be easily implemented using depth- first search. An algorithm is given for topological sorting.
