Expanded telecommunications was deemed a serious need for end users. The "Local Market" and "Last Mile" market segments have largely consolidated into "natural utilities". Competition and access problems occur if new providers enter the local market and desire competitive access and service to end users. Local and…

Since the days Internet traffic proliferated, measurement, monitoring and analysis of network traffic have been critical to not only the basic understanding of large networks, but also to seek improvements in resource management, traffic engineering and security. At the current times traffic in wireless local and wide area networks are facing…

Based on a request for information (RFI) submitted to The University Community Next Generation Innovation Project (Gig.U), the paper describes a model for universities to develop next generation broadband infrastructure in their communities. In the our view universities can play a critical role in spurring next generation networks into their…

Discusses the need for standards allowing computer-to-computer communication and gives examples of technical issues. The seven-layer framework of the Open Systems Interconnection (OSI) Reference Model is explained and illustrated. Sidebars feature public data networks and Recommendation X.25, OSI standards, OSI layer functions, and a glossary.…

A compact atlas--"Information Highways: Mapping Information Delivery Networks in the Pacific Northwest"--provides a model for assimilating large volumes of information dealing with generic topics. It combines data and information blocks with information technology graphics blocks and maps showing the actual locations of information…

Describes Integrated Services Digital Networks (ISDN), which, combined with desktop workstations, will provide access to voice, text, and video telecommunications. Telecommunications technology is discussed, the use of desktop workstations to facilitate ISDN is described, and possible future uses of ISDN technology in distance education are…

Describes the layered model of Open Systems Interconnection (OSI); summarizes the three upper and lower layers; and discusses data communications standards associated with specific layers. Architectural concepts are explored, including hierarchy and abstraction, levels of dialogue, internetworking, and end-to-end communication. OSI is compared…

Explains how the Directory Service (CCITT X.500/ISO 9594) became an international standard in response to the difficulties of keeping data on information network users current and accessible. Uses of X.500 are described, a technical overview is provided, its functions and protocols are assessed, and directory projects and products are discussed.…

Provides an overview of the current state of networking technology in rural libraries and describes a model for educating rural librarians in accessing electronic networks. Topics discussed include information needs in rural libraries; telecommunications technology access in rural areas; and examples of services to enhance information access.…

Describes the use of infometry, or informational geometry, to meet the challenges of information service businesses. Highlights include theoretical models for cognitive coordination and genetic programming; electronic information packaging; marketing electronic information products, including cost-benefit analyses; and recapitalization, including…

This report describes and evaluates the first year of a demonstration project to develop an on-demand telecommunications network linking four remote hospitals in southwestern Ohio to the University of Cincinnati Medical Center. The Telecommunications Information Network (TIN) is designed to allow health care professionals at those hospitals to…

Discusses how various Open Systems Interconnection (OSI) application layer protocols can be used together, along with the Presentation and Session protocols, to support the interconnection requirements of applications. Application layer protocol standards that are currently available or under development are reviewed, and the File, Transfer,…

The edi conceptual model is being developed to define common structures, services, and processes that syntax-specific standards like X12 and EDIFACT could adopt. Open Systems Interconnection (OSI) is of interest to edi because of its potential to help enable global interoperability across Electronic Data Interchange (EDI) functional groups. A…

This report summarizes the roundtable on information technology which brought together leaders from business, government, the non-profit sector, and academia to explore the use of complex adaptive systems as a model for determining information technology's role in both the workplace and diverse societal settings. Topics covered in this document…

Communications media have long been acknowledged as the site of intense political struggle over issues of access to, control over, and representations in these media. That communications research is likewise the site of struggle between the various paradigms of the discipline is, however, troubling to the neophyte communication scholar. For well…
