Regional Failure Events in Communication Networks
This book presents a comprehensive study covering the design and application of models and algorithms for assessing the joint device failures of telecommunication backbone networks caused by large-scale regional disasters. At first, failure models are developed to make use of the best data available; in turn, a set of fast algorithms for determining the resulting failure lists are described; further, a theoretical analysis of the complexity of the algorithms and the properties of the failure lists is presented, and relevant practical case studies are investigated. Merging concepts and tools from complexity theory, combinatorial and computational geometry, and probability theory, a comprehensive set of models is developed for translating the disaster hazard in informative yet concise data structures. The information available on the network topology and the disaster hazard is then used to calculate the possible (probabilistic) network failures. The resulting sets of resources that are expected to break down simultaneously are modeled as a collection of Shared Risk Link Groups (SRLGs), or Probabilistic SRLGs. Overall, this book presents improved theoretical methods that can help predicting disaster-caused network malfunctions, identifying vulnerable regions, and assessing precisely the availability of internet services, among other applications.
Guide to Disaster-Resilient Communication Networks
This authoritative volume presents a comprehensive guide to the evaluation and design of networked systems with improved disaster resilience. The text offers enlightening perspectives on issues relating to all major failure scenarios, including natural disasters, disruptions caused by adverse weather conditions, massive technology-related failures, and malicious human activities. Topics and features: describes methods and models for the analysis and evaluation of disaster-resilient communication networks; examines techniques for the design and enhancement of disaster-resilient systems; provides a range of schemes and algorithms for resilient systems; reviews various advanced topics relating to resilient communication systems; presents insights from an international selection of more than 100 expert researchers working across the academic, industrial, and governmental sectors. This practically-focused monograph, providing invaluable support on topics of resilient networking equipment and software, is an essential reference for network professionals including network and networked systems operators, networking equipment vendors, providers of essential services, and regulators. The work can also serve as a supplementary textbook for graduate and PhD courses on networked systems resilience.
Resilient Routing in Communication Networks
This practically focused monograph addresses the latest issues of resilient routing in networked systems. It consists of three parts and offers an in-depth introduction to the resilience of networked systems (Part I), a detailed description of schemes of resilient routing (Part II), and examples of the application of resilience mechanisms in selected communication scenarios (Part III). Topics and features: presents the essentials of network resilience; highlights the main causes of network node and link failures; elaborates on the costs and benefits of investing in resilience; discusses the taxonomy of challenges, faults, attributes, and disciplines of resilience; overviews the major metrics useful in evaluating resilience; provides a detailed classification of resilient routing schemes; analyzes the features of optimization models for selected problems of resilient routing; illustrates the properties of computationally efficient methods for determining the shortest sets of disjoint communication paths; shows the practical use of resilient routing mechanisms in selected communication scenarios with a particular focus on up-to-date concepts such as network virtualization or content-centric networking.
