Abstract

Recent growth of the Internet has greatly increased the amount of information that is accessible and the number of resources that are available to users. To exploit this growth, it must be possible for users to find the information and resources they need. Existing techniques for organizing systems have evolved from those used on centralized systems, but these techniques are inadequate for organizing information on a global scale. This article describes Prospero, a distributed file system based on the Virtual System Model. Prospero provides tools to help users organize Internet resources. These tools allow users to construct customized views of available resources, while taking advantage of the structure imposed by others. Prospero provides a framework that can tie together various indexing services producing the fabric on which resource discovery techniques can be applied.

Abstract

Purpose

This paper seeks to present six key articles from the archives of Internet Research within a research framework, covering infrastructure, organization, commerce, governance, linking, and interface.

Design/methodology/approach

The six articles are introduced, summarized, and used to focus attention on each of the core areas of research that impacted the growth of the Internet.

Findings

The prism of time is one of the most powerful tools of observation available to scientists and researchers. Palaeontologists think in terms of aeons, archaeologists consider millennia a mere starting‐point, even the biologists, chemists, and physicists have centuries of prior research to consider. Internet Research, the Journal, is only 20 years old – and the field only slightly older than that. Yet what decades those have been. Six articles from the early years of Internet Research epitomize much of the innovation, excitement, challenges and vision that would reshape the world. While tremendous advances in technology have been made in the past 20 years, a number of the original issues and challenges remain unresolved.

Practical implications

The paper serves to frame the historic articles within a broader research context.

Originality/value

The paper provides a conceptual framework for researchers seeking insights into some of the early formative research on the Internet and web.

Abstract

Purpose

This paper aims to discuss the Silver and Golden ticket exploits that usually exists in the existing systems. To overcome these challenges, the data is first encrypted and then the ticket is granted to the validated user. The users are validated using the user privileges. The security levels of the proposed model are compared with the existing models and provide a better performance using the Key Distribution Centre (KDC). The number of authentication and authorization levels present in the existing and proposed model is also evaluated.

Design/methodology/approach

The methodology designed in this paper is discussed in this section. The existing models are designed in such a way that the client ID first asked to send an authorization request to the Authentication Server. The server looks up the user in its database and then sends back a ticket generated by it to the client to obtain services for the Service center. Numerous models have some additional features to these systems where the theme of KDC was introduced. The Key Distribution Centre (KDC), which is a set of nodes in a network where the data could be distributed and stored, such that any kind of attack on a single KDC will not impact other KDC and the data stored in it. The nodes other than the KDC in the network are termed as the slave nodes. The slave nodes communicate with each other within the network depending on the topology of the entire network. In this paper, the authors have used the Kerberos protocol for adding more security functions in the entire network. The system developed consists of a client, server and a set of nodes connected to each other in a ring fashion.

Findings

The proposed model provides security to the information being used by making use of the Kerberos protocol. Additional features and algorithms such as the use of the ticket-granting approach have been added at the protocol to make it more secure than the existing models. The ticket generation is done at the server-side that makes the user have proper authentication to make use of the services available from the server-side. The model is designed in such a way that it could remain operational even during the time of denial of service. As future work, use of machine learning and deep learning could be used to predict the attack on the network well before it is being misused.

Originality/value

The paper discusses the Silver and Golden ticket exploits that usually exists in the existing systems. To overcome these challenges, the data is first encrypted and then the ticket is granted to the validated user. The users are validated using the user privileges. The security levels of the proposed model are compared with the existing models and provide a better performance using the Key Distribution Centre (KDC). The number of authentication and authorization levels present in the existing and proposed model is also evaluated.

Abstract

Explains the necessity for measurement of Internet growth so that capacity, commercial potential, etc. may be planned and assessed. Argues that this cannot be measured merely by packet counts and user registrations. Presents detailed analysis of over 13,000 sites, worldwide. Develops a mathematical model which can be used to predict growth, by individual countries and globally. Offers further topics for future research.

Abstract

This article summarizes a study that identified and described federal information inventory/locator systems. Such locator systems provide an important means of accessing a range of government information not previously available to the public or other government officials. Overall, the study's goal was to improve access to and use of U.S. government information. The study produced a final report describing study efforts, identifying issues and conclusions, and recommending the design of an networked‐based government‐wide information inventory/locator system (GIILS) (Volume I), the Federal Locator Database (FLD) — a machine‐readable database of descriptive information on some 250 federal databases, of which fifty‐three met the study's criteria as a locator, and a user's guide to that database (Volume II includes a machine‐readable version of the database and the user guide and codebook). The study recommends that the U.S. Office of Management and Budget develop a policy framework requiring agencies to design and maintain machine‐readable locators, meeting certain requirements and standards and that these be accessible over the Internet/NREN.

Abstract

Project REEL (Resources for Early Educator Learning) was a quasi-experimental, delayed-treatment professional development (PD) design to provide training, coaching, and materials to 220 early childhood educators (ECEs) in 85 diverse, high-needs settings (family, group, and center-based) across Tennessee. Its two primary goals were to (1) increase the frequency of research-based classroom learning experiences that promote language/literacy, numeracy, and social/emotional development among diverse early learners through training and coaching to ECEs and (2) improve the language/literacy, numeracy, and social/emotional readiness of children in low-income areas through research-based training of ECEs and parents. Even with differences in ECEs’ educational backgrounds and diverse settings, teachers in both treatment groups improved and maintained their knowledge and skills in response to the intervention. Preschool children in two cohorts showed significant improvements in most language and literacy measures over the course of an academic year, and improvements were often beyond that due to maturation (using age-controlled measures). Given the amount of improvement seen across a wide array of measures, there is substantial convergent evidence that the Project REEL PD approach was successful in promoting long-lasting improvements in the practices of ECEs in diverse settings and from diverse backgrounds. This chapter follows the development, implementation, and results of two literacy-related modules (“Print Awareness” and “Book Strategies”) for directors and teachers of three- and four-year-olds. These modules are representative of our training design, with its intensive focus on coaching in the diverse settings, and will provide the most beneficial model for other ECE professional developers to follow.
