This book constitutes the refereed proceedings of the 5th International Conference on Autonomous Infrastructure, Management and Security, AIMS 2011, held in Nancy, France, in June 2011. The 11 revised full papers presented together 11 papers of the AIMS PhD workshops were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on security management, autonomic network and service management (PhD workshop), policy management, P2P and aggregation schemes, and monitoring and security (PhD workshop).

Networks as sets of autonomous organisations working together to achieve individual and shared goals are becoming increasingly important across many areas of public administration. The importance of networks is well known but most analysts would agree that we do not know enough about the dynamics and effectiveness of networks in relation to their internal operations. This is a significant problem as security, intelligence, law enforcement and many other agencies are increasingly required to organise in and through networks to provide national security. In this comprehensive analysis, Chad Whelan presents a highly innovative, qualitative study of networks in the field of national security. Developing our understanding of 'organisational networks' in organisational theory, management and public administration, and 'security networks' in criminology and international relations, he presents a multi-disciplinary analysis of network forms of organisation. Whelan puts forward a methodological framework involving five levels of analysis - structural, cultural, policy, technological and relational - with which we can better analyse and understand the dynamics and effectiveness of networks. This framework is applied to public sector networks operating in the field of counter-terrorism in Australia in a way that is highly relevant to researchers and practitioners in many contexts where government departments and agencies, and the private sector, need to work together. Networks and National Security: Dynamics, Effectiveness and Organisation not only advances our knowledge of networks and national security but also assists with the essential tasks of evaluating and managing networks. Written in a clear and accessible style and featuring a wealth of first-hand accounts concerning the inside operations of networks, this book deals with the crucial subject of inter-agency coordination in the important field of national security.

Collaboration of organizations reshapes traditional managerial practices and creates new inter-organizational contexts for strategy, coordination and control, information and knowledge management. Heralded as organizational forms of the future, networks are at the same time fragile and precarious organizational arrangements, which regularly fail. In order to investigate the new realities created by technology-enabled forms of network organizations and to address the emerging managerial challenges, this book introduces an integrative view on inter-firm network management. Centred on a network life cycle perspective, strategic, economic and relational facets of business networking are explored. The network management framework is illustrated onto a broad range of European inter-firm network examples in various industries rendering insights for new management practices.

This book provides a timely and comprehensive study of dynamic resource management for network slicing in service-oriented fifth-generation (5G) and beyond core networks. This includes the perspective of developing efficient computation resource provisioning and scheduling solutions to guarantee consistent service performance in terms of end-to-end (E2E) data delivery delay. Network slicing is enabled by the software defined networking (SDN) and network function virtualization (NFV) paradigms. For a network slice with a target traffic load, the E2E service delivery is enabled by virtual network function (VNF) placement and traffic routing with static resource allocations. When data traffic enters the network, the traffic load is dynamic and can deviate from the target value, potentially leading to QoS performance degradation and network congestion. Data traffic has dynamics in different time granularities. For example, the traffic statistics (e.g., mean and variance) can be non-stationary and experience significant changes in a coarse time granularity, which are usually predictable. Within a long time duration with stationary traffic statistics, there are traffic dynamics in small timescales, which are usually highly bursty and unpredictable. To provide continuous QoS performance guarantee and ensure efficient and fair operation of the network slices over time, it is essential to develop dynamic resource management schemes for the embedded services in the presence of traffic dynamics during virtual network operation. Queueing theory is used in system modeling, and different techniques including optimization and machine learning are applied to solving the dynamic resource management problems. Based on a simplified M/M/1 queueing model with Poisson traffic arrivals, an optimization model for flow migration is presented to accommodate the large-timescale changes in the average traffic rates with average E2E delay guarantee, while addressing a trade-off between load balancing and flow migration overhead. To overcome the limitations of Poisson traffic model, the authors present a machine learning approach for dynamic VNF resource scaling and migration. The new solution captures the inherent traffic patterns in a real-world traffic trace with non-stationary traffic statistics in large timescale, predicts resource demands for VNF resource scaling, and triggers adaptive VNF migration decision making, to achieve load balancing, migration cost reduction, and resource overloading penalty suppression in the long run. Both supervised and unsupervised machine learning tools are investigated for dynamic resource management. To accommodate the traffic dynamics in small time granularities, the authors present a dynamic VNF scheduling scheme to coordinate the scheduling among VNFs of multiple services, which achieves network utility maximization with delay guarantee for each service. Researchers and graduate students working in the areas of electrical engineering, computing engineering and computer science will find this book useful as a reference or secondary text. Professionals in industry seeking solutions to dynamic resource management for 5G and beyond networks will also want to purchase this book.

This monograph treats the application of numerous graph-theoretic algorithms to a comprehensive analysis of dynamic enterprise networks. Network dynamics analysis yields valuable information about network performance, efficiency, fault prediction, cost optimization, indicators and warnings. Based on many years of applied research on generic network dynamics, this work covers a number of elegant applications (including many new and experimental results) of traditional graph theory algorithms and techniques to computationally tractable network dynamics analysis to motivate network analysts, practitioners and researchers alike.

This book explores the basic traits of inter-organizational networks, examining the interplay between structure, dynamics, and performance from a governance perspective. The book assumes a novel theoretical angle based on the interpretation of networks as multiple systems, and advances the theory in the realm of network effectiveness and failure. Composed of two parts, theoretical and empirical, The Network Organization clarifies the literature on networks, offering a systematic review, and provides a new perspective on their integration with other streams of research focusing on under-studied issues such as agency, micro-dynamics, and network effectiveness. The second part proposes the analysis of the tourism destination of Venice, with a specific focus on the network between the Venice Film Festival, the hospitality system, and the local institutions. By exploring the pervasion of networks in modern social and economic life, this book will be valuable to students, researchers, practitioners and policy-makers.
