Download or read book Structured Peer to Peer Systems written by Dmitry Korzun and published by Springer Science & Business Media. This book was released on 2012-11-12 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of structured P2P systems has seen fast growth upon the introduction of Distributed Hash Tables (DHTs) in the early 2000s. The first proposals, including Chord, Pastry, Tapestry, were gradually improved to cope with scalability, locality and security issues. By utilizing the processing and bandwidth resources of end users, the P2P approach enables high performance of data distribution which is hard to achieve with traditional client-server architectures. The P2P computing community is also being actively utilized for software updates to the Internet, P2PSIP VoIP, video-on-demand, and distributed backups. The recent introduction of the identifier-locator split proposal for future Internet architectures poses another important application for DHTs, namely mapping between host permanent identity and changing IP address. The growing complexity and scale of modern P2P systems requires the introduction of hierarchy and intelligence in routing of requests. Structured Peer-to-Peer Systems covers fundamental issues in organization, optimization, and tradeoffs of present large-scale structured P2P systems, as well as, provides principles, analytical models, and simulation methods applicable in designing future systems. Part I presents the state-of-the-art of structured P2P systems, popular DHT topologies and protocols, and the design challenges for efficient P2P network topology organization, routing, scalability, and security. Part II shows that local strategies with limited knowledge per peer provide the highest scalability level subject to reasonable performance and security constraints. Although the strategies are local, their efficiency is due to elements of hierarchical organization, which appear in many DHT designs that traditionally are considered as flat ones. Part III describes methods to gradually enhance the local view limit when a peer is capable to operate with larger knowledge, still partial, about the entire system. These methods were formed in the evolution of hierarchical organization from flat DHT networks to hierarchical DHT architectures, look-ahead routing, and topology-aware ranking. Part IV highlights some known P2P-based experimental systems and commercial applications in the modern Internet. The discussion clarifies the importance of P2P technology for building present and future Internet systems.

Download or read book Peer to Peer Computing written by Quang Hieu Vu and published by Springer Science & Business Media. This book was released on 2009-10-20 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peer-to-peer (P2P) technology, or peer computing, is a paradigm that is viewed as a potential technology for redesigning distributed architectures and, consequently, distributed processing. Yet the scale and dynamism that characterize P2P systems demand that we reexamine traditional distributed technologies. A paradigm shift that includes self-reorganization, adaptation and resilience is called for. On the other hand, the increased computational power of such networks opens up completely new applications, such as in digital content sharing, scientific computation, gaming, or collaborative work environments. In this book, Vu, Lupu and Ooi present the technical challenges offered by P2P systems, and the means that have been proposed to address them. They provide a thorough and comprehensive review of recent advances on routing and discovery methods; load balancing and replication techniques; security, accountability and anonymity, as well as trust and reputation schemes; programming models and P2P systems and projects. Besides surveying existing methods and systems, they also compare and evaluate some of the more promising schemes. The need for such a book is evident. It provides a single source for practitioners, researchers and students on the state of the art. For practitioners, this book explains best practice, guiding selection of appropriate techniques for each application. For researchers, this book provides a foundation for the development of new and more effective methods. For students, it is an overview of the wide range of advanced techniques for realizing effective P2P systems, and it can easily be used as a text for an advanced course on Peer-to-Peer Computing and Technologies, or as a companion text for courses on various subjects, such as distributed systems, and grid and cluster computing.

Download or read book P2P Networking and Applications written by John Buford and published by Morgan Kaufmann. This book was released on 2009-03-11 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peer-to-Peer (P2P) networks enable users to directly share digital content (such as audio, video, and text files) as well as real-time data (such as telephony traffic) with other users without depending on a central server. Although originally popularized by unlicensed online music services such as Napster, P2P networking has recently emerged as a viable multimillion dollar business model for the distribution of information, telecommunications, and social networking. Written at an accessible level for any reader familiar with fundamental Internet protocols, the book explains the conceptual operations and architecture underlying basic P2P systems using well-known commercial systems as models and also provides the means to improve upon these models with innovations that will better performance, security, and flexibility. Peer-to-Peer Networking and Applications is thus both a valuable starting point and an important reference to those practitioners employed by any of the 200 companies with approximately $400 million invested in this new and lucrative technology. Uses well-known commercial P2P systems as models, thus demonstrating real-world applicability. Discusses how current research trends in wireless networking, high-def content, DRM, etc. will intersect with P2P, allowing readers to account for future developments in their designs. Provides online access to the Overlay Weaver P2P emulator, an open-source tool that supports a number of peer-to-peer applications with which readers can practice.

Download or read book Handbook of Peer to Peer Networking written by Xuemin Shen and published by Springer. This book was released on 2010-03-03 with total page 1500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peer-to-peer networking is a disruptive technology for large scale distributed app- cations that has recently gained wide interest due to the successes of peer-to-peer (P2P) content sharing, media streaming, and telephony applications. There are a large range of other applications under development or being proposed. The - derlying architectures share features such as decentralizaton, sharing of end system resources, autonomy, virtualization, and self-organization. These features constitute the P2P paradigm. This handbook broadly addresses a large cross-section of c- rent research and state-of-the-art reports on the nature of this paradigm from a large number of experts in the ?eld. Several trends in information and network technology such as increased perf- mance and deployment of broadband networking, wireless networking, and mobile devices are synergistic with and reinforcing the capabilities of the P2P paradigm. There is general expectation in the technical community that P2P networking will continue to be an important tool for networked applications and impact the evo- tion of the Internet. A large amount of research activity has resulted in a relatively short time, and a growing community of researchers has developed. The Handbook of Peer-to-Peer Networking is dedicated to discussions on P2P networks and their applications. This is a comprehensive book on P2P computing.

Available in PDF, EPUB and Kindle. Book excerpt: While people are now using peer-to-peer (P2P) applications for various processes, such as file sharing and video streaming, many research and engineering issues still need to be tackled in order to further advance P2P technologies. Peer-to-Peer Computing: Applications, Architecture, Protocols, and Challenges provides comprehensive theoretical and practical coverage of the major features of contemporary P2P systems and examines the obstacles to further success. Setting the stage for understanding important research issues in P2P systems, the book first introduces various P2P network architectures. It then details the topology control research problem as well as existing technologies for handling topology control issues. The author describes novel and interesting incentive schemes for enticing peers to cooperate and explores recent innovations on trust issues. He also examines security problems in a P2P network. The final chapter addresses the future of the field. Throughout the text, the highly popular P2P IPTV application, PPLive, is used as a case study to illustrate the practical aspects of the concepts covered. Addressing the unique challenges of P2P systems, this book presents practical applications of recent theoretical results in P2P computing. It also stimulates further research on critical issues, including performance and security problems.

Download or read book Peer to Peer written by Andy Oram and published by "O'Reilly Media, Inc.". This book was released on 2001-02-26 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "peer-to-peer" has come to be applied to networks that expect end users to contribute their own files, computing time, or other resources to some shared project. Even more interesting than the systems' technical underpinnings are their socially disruptive potential: in various ways they return content, choice, and control to ordinary users. While this book is mostly about the technical promise of peer-to-peer, we also talk about its exciting social promise. Communities have been forming on the Internet for a long time, but they have been limited by the flat interactive qualities of email and Network newsgroups. People can exchange recommendations and ideas over these media, but have great difficulty commenting on each other's postings, structuring information, performing searches, or creating summaries. If tools provided ways to organize information intelligently, and if each person could serve up his or her own data and retrieve others' data, the possibilities for collaboration would take off. Peer-to-peer technologies along with metadata could enhance almost any group of people who share an interest--technical, cultural, political, medical, you name it. This book presents the goals that drive the developers of the best-known peer-to-peer systems, the problems they've faced, and the technical solutions they've found.

Available in PDF, EPUB and Kindle. Book excerpt: Not since Marx identified the manufacturing plants of Manchester as the blueprint for the new capitalist society has there been a more profound transformation of the fundamentals of our social life. As capitalism faces a series of structural crises, a new social, political and economic dynamic is emerging: peer to peer. What is peer to peer? Why is it essential for building a commons-centric future? How could this happen? These are the questions this book tries to answer. Peer to peer is a type of social relations in human networks, as well as a technological infrastructure that makes the generalization and scaling up of such relations possible. Thus, peer to peer enables a new mode of production and creates the potential for a transition to a commons-oriented economy.

Download or read book Effective Peer Learning written by Keith Topping and published by Taylor & Francis. This book was released on 2017-03-31 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peer learning allows a positive use of differences between pupils, turning them into learning opportunities. Yet education professionals often remain unfamiliar with the principles necessary to guarantee its effectiveness. The aim of this book is to help practitioners establish well-structured and effective peer learning projects using a variety of methods. It introduces and defines cooperative learning (mutual peer interaction) and peer tutoring (directional peer interaction) – outlining general organisational principles that will help practitioners implement peer learning in either of these forms. The authors consider how to prepare and train learners to undertake their roles effectively, and how to organise and monitor the process of interaction as it is happening. They then look at how these systems actually operate in the classroom, exploring how the organisational principles work in practice and giving many practical examples. Subsequently three successive chapters consider how to structure peer interactions in cooperative learning, same-age peer tutoring and cross-age peer tutoring. Finally, the advantages and problems, and the potential and challenges, of peer learning are examined. The book should be read in stages, with each part being able to be read on its own – thus providing time for reflection. Within each part, readers can choose to focus on cooperative learning or peer tutoring. The successive focuses on definitions, general principles of implementation and practical issues of implementation should help practitioners build their skills and confidence. Many choices between methods are described, and when teachers are confident in one method they may then consider trying a new method. It is the authors' hope that the book will become a model for peer learning by sharing with readers the skills of other practitioners, and thereby helping all children to develop to their full potential.

Available in PDF, EPUB and Kindle. Book excerpt: Starting with Napster and Gnutella, peer-to-peer systems became an integrated part of the Internet fabric attracting millions of users. According to recent evaluations, peer-to-peer traffic now exceeds Web traffic, once the dominant traffic on the Internet. While the most popular peer-to-peer applications remain file sharing and content distribution, new applications such as Internet telephony are emerging. Within just a few years, the huge popularity of peer-to-peer systems and the explosion of peer-to-peer research have created a large body of knowledge, but this book is the first textbook-like survey to provide an up-to-date and in-depth introduction to the field. This state-of-the-art survey systematically draws together prerequisites from various fields, presents techniques and methodologies in a principled and coherent way, and gives a comprehensive overview on the manifold applications of the peer-to-peer paradigm. Leading researchers contributed their expert knowledge to this book, each in his/her own specific area. Lecturers can choose from the wide range of 32 tightly integrated chapters on all current aspects of P2P systems and applications, and thus individually tailor their class syllabi. R&D professionals active in P2P will appreciate this book as a valuable source of reference and inspiration.

This book was released on 2010-04-11 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: At times when the IT manager’s best friend is systems consolidation (which is a euphemism for centralisation), it may come somewhat as a surprise for you that this book investigates decentralisation in the context of content management systems. It may seem quite obvious that content will and should be managed by the party who creates and owns the content, and hence should be held in a—somewhat—centralised and managed location. However, over the past few years, we have been witnesses of some important trends and developments which call for novel ways of thinking about content management and maybe even broader, about computer systems in general. First, ongoing business globalization creates natural distribution of information at a corp- ate level, as well as decentralization of control over business resources and business processes. Changing alliances with partners require ?exible architectures for content management that canadapttochangingconstellations, roles, andaccessrights. Second, theneedforoutsourcing and resource e?ciency has brought about concepts of virtualization, recently culminating in the cloud computing buzzword. Virtualization of content management services requires - tremely scalable and ?exible underlying information and communication architectures. These kinds of solutions are theoretically and practically impossible to implement based on c- tralised client-server architectures. Third, we are currently experiencing a dramatic shift in the roles of consumers in the Internet. The times have gone when quality content was only delivered by publishers and news agencies. Wikis and other Web 2. 0 tools empower consumers to produce and publish their personal content.

Download or read book Peer to Peer Leadership written by Mila Baker and published by Berrett-Koehler Publishers. This book was released on 2014-01-06 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our leadership models are stuck in an Industrial Age, top-down mentality. But in our complex, data-drenched, 24/7 world, there is simply too much information coming from too many different directions too quickly for any one leader or group to stay on top of it. Hierarchy is breaking down everywhere—why should leadership be any different? Inspired by the peer-to-peer model of computing used in social networking and crowdsource technologies, Mila Baker shows a new way to lead. Organizations, she says, must become networks of "equipotent" nodes of power—peer leaders. The job of the leader is now to set the overall goals and direction and optimize the health of that network, not tell it what to do. In these organizations, leadership roles shift rapidly to fit the needs of any given situation. Information flows freely so those who need it can find it easily and act on it immediately. Feedback becomes an organic part of the workflow, enabling rapid course corrections. Baker shows how companies like Gore and Herman Miller have achieved long-term success practicing these principles and provides a structure that any organization can adapt to build flexibility, resiliency, and accountability.
