  Local area networks (LAN) are extremely popular in both the consumer and enterprise markets. The LAN has become ubiquitous throughout both of these markets as the Internet has grown in size and use, PCs have become readily available at an attractive price point, and high-speed broadband connections have become readily available. Yet, with all the usage of LANs for connecting computer equipment of all types, there is no standard, formal industry accepted definition for a local area network (Comer, 2006, 15). According to the Institute of Electrical and Electronics Engineers (IEEE), a local area network is describes as being “distinguished from other types of data networks in that they are optimized for a moderate-sized geographic area, such as a single office building, a warehouse, or a campus” (2001). Some definitions include a distinction concerning physical proximity (Palmer & Sinclair, 2003, 2), while others provide definitions based on topology, physical medium, or performance characteristics. Vendors, governing/standards bodies, and even network managers have yet their own definition of the exact meaning of what a local area network is and means. These definitions tend to use terminology loosely and allow the end user to determine actual meaning based on context and technologies used. The following discussion will give the reader the foundational information of LANs, including LAN addressing (both MAC and IP addressing), architecture, and protocols.Request access from your librarian to read this chapter's full text.

  When network services must be distributed over large geographic areas, it is essential to have an understanding of the telecommunication systems on which such distribution depends. One of the most significant differences between wide area networks (WANs) and local area networks (LANs) is the general dependency on third-party carriers to provide these transmission services. Whenever data is being sent across a WAN it must be routed between locations.Request access from your librarian to read this chapter's full text.

• Creation of a security solution selection matrix for WLAN implementations using real options

  Annual Information Security Symposium · 2004-03-23

  article

  The purpose of this project was to create a Security Solution Selection Matrix for WLAN implementations using Luehrman's Real Options methodology. The methodology was used to evaluate the effectiveness of WLAN security techniques for the following environments: Small Office Home Office (SOHO)/Home, Corporate, and Public Access. The matrix allowed for the security techniques to be compared to one another so that a WLAN user or network administrator could select the appropriate technique, or a combination of techniques, to implement based on the individual's environment. Through this project a method is developed for applying Real Options to a technologically-associated, assessment paradigm. This poster presents this approach of employing Real Options for a technologically-associated, assessment paradigm.

• Strategic decisions on technology selections for facilitating a network/systems laboratory using real options & total cost of ownership theories

  2003-10-16 · 12 citations

  articleSenior author

  This paper addresses the selection of technologies that provide each student group a dedicated environment on a non-dedicated host machine. The authors investigated different combinations of enabling technologies and approaches, such as virtual machine technology, storage technology, and host operating system. Performance tests were developed and executed to profile the performance of the technologies. The results of this work provide an evaluation of the studied technologies and a selection guide for institutions to assist in technology selection to facilitate a system and networking laboratory.

• Developing a public key infrastructure for use in a teaching laboratory

  2003-10-16 · 2 citations

  article1st authorCorresponding

  Founded on the principle of easy information interchange the Internet is an inherently unsafe communication medium. Despite this inherent insecurity electronic mail continues to grow as a key communication technology. Individuals and businesses both large and small have come to rely on electronic mail. Fortunately technologies have evolved that address the lack of security in the base Internet electronic mail standards. Through the use of Public Key Infrastructure (PKI) technologies it is possible to build and deploy a secure electronic mail system that addresses the three key areas of security: authentication, authorization, and non-repudiation.This paper presents an implementation plan for deploying a PKI infrastructure for use in teaching these technologies to students in a laboratory environment. The techniques implemented and problems encountered are representative of those likely to be experienced by students in a real world implementation.

  From the Publisher: These days, networks and information systems are more than just a technological service segment of a company, they are vital variables in the business equation. This book takes a business-first approach to networks focusing on how to analyze, implement and manage local area networks. Drawing on extensive case studies, it provides a thorough examination of the business application, data, network, and technology issues surrounding the successful implementation of local area network-based client/server systems. It also provides working models which readers can use to organize their own systems.
