Network Troubleshooting Tools: Help for Network Administrators
by Joseph D SloanOver the years, thousands of tools have been developed for debugging TCP/IP networks. They range from very specialized tools that do one particular task, to generalized suites that do just about everything except replace bad Ethernet cables. Even better, many of them are absolutely free. There's only one problem: who has time to track them all down, sort through them for the best ones for a particular purpose, or figure out how to use them?Network Troubleshooting Tools does the work for you--by describing the best of the freely available tools for debugging and troubleshooting. You can start with a lesser-known version of ping that diagnoses connectivity problems, or take on a much more comprehensive program like MRTG for graphing traffic through network interfaces. There's tkined for mapping and automatically monitoring networks, and Ethereal for capturing packets and debugging low-level problems.This book isn't just about the tools available for troubleshooting common network problems. It also outlines a systematic approach to network troubleshooting: how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise, so you can solve them more effectively.The topics covered in this book include:Understanding your networkConnectivity testingEvaluating the path between two network nodesTools for capturing packetsTools for network discovery and mappingTools for working with SNMPPerformance monitoringTesting application layer protocolsSoftware sourcesIf you're involved with network operations, this book will save you time, money, and needless experimentation.

Networked
by Lee Rainie Barry WellmanDaily life is connected life, its rhythms driven by endless email pings and responses, the chimes and beeps of continually arriving text messages, tweets and retweets, Facebook updates, pictures and videos to post and discuss. Our perpetual connectedness gives us endless opportunities to be part of the give-and-take of networking. Some worry that this new environment makes us isolated and lonely. But in Networked, Lee Rainie and Barry Wellman show how the large, loosely knit social circles of networked individuals expand opportunities for learning, problem solving, decision making, and personal interaction. The new social operating system of "networked individualism" liberates us from the restrictions of tightly knit groups; it also requires us to develop networking skills and strategies, work on maintaining ties, and balance multiple overlapping networks. Rainie and Wellman outline the "triple revolution" that has brought on this transformation: the rise of social networking, the capacity of the Internet to empower individuals, and the always-on connectivity of mobile devices. Drawing on extensive evidence, they examine how the move to networked individualism has expanded personal relationships beyond households and neighborhoods; transformed work into less hierarchical, more team-driven enterprises; encouraged individuals to create and share content; and changed the way people obtain information. Rainie and Wellman guide us through the challenges and opportunities of living in the evolving world of networked individuals.
Networked Affect
by Ken Hillis Michael Petit Susanna PaasonenInvestigations of affective experiences that emerge in online settings that range from Facebook discussion forums to “smart” classrooms.Our encounters with websites, avatars, videos, mobile apps, discussion forums, GIFs, and nonhuman intelligent agents allow us to experience sensations of connectivity, interest, desire, and attachment—as well as detachment, boredom, fear, and shame. Some affective online encounters may arouse complex, contradictory feelings that resist dualistic distinctions. In this book, leading scholars examine the fluctuating and altering dynamics of affect that give shape to online connections and disconnections. Doing so, they tie issues of circulation and connectivity to theorizations of networked affect. Their diverse investigations—considering subjects that range from online sexual dynamics to the liveliness of computer code—demonstrate the value of affect theories for Internet studies. The contributors investigate networked affect in terms of intensity, sensation, and value. They explore online intensities that range from Tumblr practices in LGBTQ communities to visceral reactions to animated avatars; examine the affective materiality of software in such platforms as steampunk culture and nonprofit altporn; and analyze the ascription of value to online activities including the GTD (“getting things done”) movement and the accumulation of personal digital materials.

Networked and Distributed Predictive Control
by David Muñoz de la Peña Jinfeng Liu Panagiotis D. ChristofidesNetworked and Distributed Predictive Control presents rigorous, yet practical, methods for the design of networked and distributed predictive control systems - the first book to do so. The design of model predictive control systems using Lyapunov-based techniques accounting for the influence of asynchronous and delayed measurements is followed by a treatment of networked control architecture development. This shows how networked control can augment dedicated control systems in a natural way and takes advantage of additional, potentially asynchronous and delayed measurements to maintain closed loop stability and significantly to improve closed-loop performance. The text then shifts focus to the design of distributed predictive control systems that cooperate efficiently in computing optimal manipulated input trajectories that achieve desired stability, performance and robustness specifications but spend a fraction of the time required by centralized control systems. Key features of this book include: * new techniques for networked and distributed control system design; * insight into issues associated with networked and distributed predictive control and their solution; * detailed appraisal of industrial relevance using computer simulation of nonlinear chemical process networks and wind- and solar-energy-generation systems; and * integrated exposition of novel research topics and rich resource of references to significant recent work. A full understanding of Networked and Distributed Predictive Control requires a basic knowledge of differential equations, linear and nonlinear control theory and optimization methods and the book is intended for academic researchers and graduate students studying control and for process control engineers. The constant attention to practical matters associated with implementation of the theory discussed will help each of these groups understand the application of the book's methods in greater depth.
Networked and Event-Triggered Control Approaches in Cyber-Physical Systems
by Jinhui Zhang Yuanqing Xia Zhongqi Sun Duanduan ChenThe insertion of communication networks in feedback control loops complicates analysis and synthesis of cyber-physical systems (CPSs), and network-induced uncertainties may degrade system control performance. Thus, this book researches networked delay compensation and event-triggered control approaches for a series of CPSs subject to network-induced uncertainties. The authors begin with an introduction to the concepts and challenges of CPSs, followed by an overview of networked control approaches and event-triggered control strategies in CPSs. Then, networked delay compensation and event-triggered control approaches are proposed for CPSs with network communication delay, data dropout, signal quantization, and event-triggered communication. More specifically, networked delay compensation approaches are proposed for linear/nonlinear networked controlled plants with time-varying and random network communication delays and data dropouts. To reduce computational burden and network communication loads in CPSs, event-triggered control, self-triggered control, co-design of event-triggered control and quantized control techniques, and event-triggered disturbance rejection control approaches are also presented. This book is an essential text for researchers and engineers interested in cybersecurity, networked control, and CPSs. It would also prove useful for graduate students in the fields of science, engineering, and computer science.

Networked Feminism: How Digital Media Makers Transformed Gender Justice Movements
by Rosemary Clark-ParsonsNetworked Feminism tells the story of how activists have used media to reconfigure what feminist politics and organizing look like in the United States. Drawing on years spent participating in grassroots communities and observing viral campaigns, Rosemary Clark-Parsons argues that feminists engage in a do-it-ourselves feminism characterized by the use of everyday media technologies. Faced with an electoral system and a history of collective organizing that have failed to address complex systems of oppression, do-it-ourselves feminists do not rely on political organizations, institutions, or authorities. Instead, they use digital networks to build movements that reflect their values and meet the challenges of the current moment, all the while juggling the advantages and limitations of their media tools. Through its practitioner-centered approach, this book sheds light on feminist media activists' shared struggles and best practices at a time when collective organizing for social justice has become more important than ever.

Networked Predictive Control of Systems with Communication Constraints and Cyber Attacks
by Zhong-Hua Pang Guo-Ping Liu Donghua Zhou Dehui SunThis book presents the latest results on predictive control of networked systems, where communication constraints (e.g., network-induced delays and packet dropouts) and cyber attacks (e.g., deception attacks and denial-of-service attacks) are considered. For the former, it proposes several networked predictive control (NPC) methods based on input-output models and state-space models respectively. For the latter, it designs secure NPC schemes from the perspectives of information security and real-time control. Furthermore, it uses practical experiments to demonstrate the effectiveness and applicability of all the methods, bridging the gap between control theory and practical applications. The book is of interest to academic researchers, R&D engineers, and graduate students in control engineering, networked control systems and cyber-physical systems.
Networked Press Freedom: Creating Infrastructures for a Public Right to Hear
by Mike AnannyReimagining press freedom in a networked era: not just a journalist's right to speak but also a public's right to hear. In Networked Press Freedom, Mike Ananny offers a new way to think about freedom of the press in a time when media systems are in fundamental flux. Ananny challenges the idea that press freedom comes only from heroic, lone journalists who speak truth to power. Instead, drawing on journalism studies, institutional sociology, political theory, science and technology studies, and an analysis of ten years of journalism discourse about news and technology, he argues that press freedom emerges from social, technological, institutional, and normative forces that vie for power and fight for visions of democratic life. He shows how dominant, historical ideals of professionalized press freedom often mistook journalistic freedom from constraints for the public's freedom to encounter the rich mix of people and ideas that self-governance requires. Ananny's notion of press freedom ensures not only an individual right to speak, but also a public right to hear. Seeing press freedom as essential for democratic self-governance, Ananny explores what publics need, what kind of free press they should demand, and how today's press freedom emerges from intertwined collections of humans and machines. If someone says, “The public needs a free press,” Ananny urges us to ask in response, “What kind of public, what kind of freedom, and what kind of press?” Answering these questions shows what robust, self-governing publics need to demand of technologists and journalists alike.
Networked Professional Learning: Emerging and Equitable Discourses for Professional Development (Research in Networked Learning)
by Allison Littlejohn Jimmy Jaldemark Emmy Vrieling-Teunter Femke NijlandOver the past decades a new form of professionalism has emerged, characterized by factors of fluidity, instability and continual change, leading to the necessitation of new forms of professional development that support agile and flexible expansion of professional practice. At the same time, the digitization of work has had a profound effect on professional practice. This digitization opens up opportunities for new forms of professional learning mediated by technologies through networked learning. Networked learning is believed to lead to a more efficient flow of complex knowledge and routine information within the organization, stimulate innovative behaviour, and result in a higher job satisfaction. In this respect, networked learning can be perceived as an important perspective on both professional and organizational development. This volume provides examples of Networked Professional Learning, it questions the impact of this emerging form of learning on the academy, and it interrogates the impact on teachers of the future. It features three sections that explore networked professional learning from different perspectives: questioning what legitimate forms of networked professional learning are across a broad sampling of professions, how new forms of professional learning impact institutions of higher education, and the value creation that Networked Learning offers professionals in broader educational, economic, and social contexts. The book is of interest to researchers in the area of professional and digital learning, higher education managers, organizational HR professionals, policy makers and students of technology enhanced learning.
