Available in PDF, EPUB and Kindle. Book excerpt: Design your networks to successfully manage their growing complexity Network professionals have often been told that today’s modern control planes would simplify their networks. The opposite has happened: Technologies like SDN and NFV, although immensely valuable, are exacerbating complexity instead of solving it. Navigating Network Complexity is the first comprehensive guide to managing this complexity in both deployment and day-to-day operations. Russ White and Jeff Tantsura introduce modern complexity theory from the standpoint of the working network engineer, helping you apply it to the practical problems you face every day. Avoiding complex mathematical models, they show how to characterize network complexity, so you can understand it and control it. The authors examine specific techniques and technologies associated with network control planes, including SDNs, fast reroute, segment routing, service chaining, and cloud computing. They reveal how each of these affects network design and complexity and help you anticipate causes of failure in highly complex systems.

Download or read book Complexity and Spatial Networks written by Aura Reggiani and published by Springer Science & Business Media. This book was released on 2009-08-14 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex systems analysis has become a fascinating topic in modern research on non-linear dynamics, not only in the physical sciences but also in the life sciences and the social sciences. After the era of bifurcation theory, chaos theory, syn- getics, resilience analysis, network dynamics and evolutionary thinking, currently we observe an increasing interest in critical transitions of dynamic real-world systems in many disciplines, such as demography, biology, psychology, economics, earth sciences, geology, seismology, medical sciences, and so on. The relevance of this approach is clearly re?ected in such phenomena as traf?c congestion, ?nancial crisis, ethnic con?icts, eco-system breakdown, health failures, etc. This has prompted a world-wide interest in complex systems. Geographical space is one of the playgrounds for complex dynamics, as is witnessed by population movements, transport ?ows, retail developments, urban expansion, lowland ?ooding and so forth. All such dynamic phenomena have one feature in common: the low predictability of uncertain interrelated events occurring at different interconnected spatio-temporal scale levels and often originating from different disciplinary backgrounds. The study of the associated non-linear (fast and slow) dynamic transition paths calls for a joint research effort of scientists from different disciplines in order to understand the nature, the roots and the con- quences of unexpected or unpredictable changes in complex spatial systems.

Download or read book Network Oriented Modeling written by Jan Treur and published by Springer. This book was released on 2016-10-03 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new approach that can be applied to complex, integrated individual and social human processes. It provides an alternative means of addressing complexity, better suited for its purpose than and effectively complementing traditional strategies involving isolation and separation assumptions. Network-oriented modeling allows high-level cognitive, affective and social models in the form of (cyclic) graphs to be constructed, which can be automatically transformed into executable simulation models. The modeling format used makes it easy to take into account theories and findings about complex cognitive and social processes, which often involve dynamics based on interrelating cycles. Accordingly, it makes it possible to address complex phenomena such as the integration of emotions within cognitive processes of all kinds, of internal simulations of the mental processes of others, and of social phenomena such as shared understandings and collective actions. A variety of sample models – including those for ownership of actions, fear and dreaming, the integration of emotions in joint decision-making based on empathic understanding, and evolving social networks – illustrate the potential of the approach. Dedicated software is available to support building models in a conceptual or graphical manner, transforming them into an executable format and performing simulation experiments. The majority of the material presented has been used and positively evaluated by undergraduate and graduate students and researchers in the cognitive, social and AI domains. Given its detailed coverage, the book is ideally suited as an introduction for graduate and undergraduate students in many different multidisciplinary fields involving cognitive, affective, social, biological, and neuroscience domains.

Download or read book Signposts in Cyberspace written by National Research Council and published by National Academies Press. This book was released on 2005-08-07 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Domain Name System (DNS) enables user-friendly alphanumeric namesâ€"domain namesâ€"to be assigned to Internet sites. Many of these names have gained economic, social, and political value, leading to conflicts over their ownership, especially names containing trademarked terms. Congress, in P.L. 105-305, directed the Department of Commerce to request the NRC to perform a study of these issues. When the study was initiated, steps were already underway to address the resolution of domain name conflicts, but the continued rapid expansion of the use of the Internet had raised a number of additional policy and technical issues. Furthermore, it became clear that the introduction of search engines and other tools for Internet navigation was affecting the DNS. Consequently, the study was expanded to include policy and technical issues related to the DNS in the context of Internet navigation. This report presents the NRC's assessment of the current state and future prospects of the DNS and Internet navigation, and its conclusions and recommendations concerning key technical and policy issues.

Download or read book Networks Complexity and Internet Regulation written by Andrés Guadamuz and published by Edward Elgar Publishing. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complexity theory as a subject has gained increasing prominence across numerous disciplines including physics, biology, sociology and economics. Large interconnected systems such as the Internet display a number of inherent architectural characteristics deeming them well-suited to the study of complex dynamic networks. This important book uses various network science-based tools to explore the contentious issue of Internet regulation. The author demonstrates that the Internet as a global communications space is a self-organizing entity that has proven problematic for regulators, and that in order to regulate cyberspace, one must first understand how the network operates. In order to illustrate how the world wide web operates, Andres Guadamuz presents case studies in copyright policy, peer-production and cyber crime, providing in-depth analyses of the challenges posed by the Internet's complex dynamic networks. The book concludes that regulatory efforts that ignore empirical evidence will ultimately encounter serious problems. Networks, Complexity and Internet Regulation introduces network theory to legal audiences and applies some of the characteristics of large distributed self-organizing networks to the topic of Internet regulation. As such, this fascinating book will prove invaluable to researchers, academics and students in the fields of Internet regulation and policy, intellectual property law and information technology law.
