'Due to their economic characteristics and also to their consequences on many aspects of collective life, information networks have always been at the edge of regulatory innovations and at the center of policy debates. The contributors of this volume combine long term visions of the factors determining regulatory policies with up-to-date analyses of technicalities to be dealt with, to provide the reader with an extended understanding of the issues and constraints shaping the future of digital networks.' Eric Brousseau, Université Paris-Dauphine, France and the European University Institute, Italy Digital markets worldwide are in rapid flux. The Internet and World Wide Web have traditionally evolved in a largely deregulated environment, but recently governments have shown great interest in this rapidly developing sector and are imposing regulations for a variety of reasons that are changing the shape of these industries. This book explores why the industrial organization of broadband ISPs, Internet backbone providers and content/application providers are in such turmoil. The expert contributors straddle the turbulent past of the telecoms sector and also contribute to its exciting though unpredictable future via positive analysis of past communications policies, which is then utilized to deduce lessons to guide future policy making decisions. It is illustrated that broadband ISPs no longer simply provide a conduit for service delivery; they are also involved in producing content and transaction services themselves, in competition with content and delivery providers. The blurring of the traditional lines between these three sectors, as each enters into the others' markets, is highlighted. The conclusion is that we are witnessing the emergence of powerful, competing platforms, linked in complex ways that challenge traditional economic analyses. Exploring governance issues, regulation and investment, next-generation service markets and wireless communication, this book will prove a fascinating and illuminating read for scholars, researchers, post-graduate students and policymakers with an interest in ICT, technology and innovation, economics and industrial organization.

Providing performance guarantees is one of the most important issues for future telecommunication networks. This book describes theoretical developments in performance guarantees for telecommunication networks from the last decade. Written for the benefit of graduate students and scientists interested in telecommunications-network performance this book consists of two parts. The first introduces the recently-developed filtering theory for providing deterministic (hard) guarantees, such as bounded delay and queue length. The filtering theory is developed under the min-plus algebra, where one replaces the usual addition with the min operator and the usual multiplication with the addition operator. As in the classical linear system theory, the filtering theory treats an arrival process (or a departure process ) as a signal and a network element as a system. Network elements, including traffic regulators and servers, can be modelled as linear filters under the min-plus algebra, and they can be joined by concatenation, "filter bank summation", and feedback to form a composite network element. The problem of providing deterministic guarantees is equivalent to finding the impulse response of composite network elements. This section contains material on: - (s, r)-calculus - Filtering theory for deterministic traffic regulation, service guarantees and networks with variable-length packets - Traffic specification - Networks with multiple inputs and outputs - Constrained traffic regulation The second part of the book addresses stochastic (soft) guarantees, focusing mainly on tail distributions of queue lengths and packet loss probabilities and contains material on: - (s(q), r(q))-calculus and q-envelope rates - The large deviation principle - The theory of effective bandwidth The mathematical theory for stochastic guarantees is the theory of effective bandwidth. Based on the large deviation principle, the theory of effective bandwidth provides approximations for the bandwidths required to meet stochastic guarantees for both short-range dependent inputs and long-range dependent inputs.

Retaining the first edition's technology-centred perspective, this book gives readers a sound understanding of packed-switched, circuit-switched and ATM networks, and techniques for controlling them.

This book provides a detailed analysis of the strategic and regulatory dimension of convergence. It offers policymakers and regulators examples from countries around the world as they address convergence.

Effective management of a communications network can be a difficult and costly activity, and even more so when the network crosses international borders. International network managers face a number of issues that are crucial to strategic decision-making, including the varying telecommunications regulations, operators, and services found within-as

Traditionally engineers devised communication services without reference to how they should be priced. In today's environment pricing is a very complex subject and in practice depends on many parameters of the actual market - including amount of traffic, architecture of the network, technology, and cost. The challenge is to provide a generic service model which accurately captures aspects such as quality and performance, and can be used to derive optimal pricing strategies. Recent technology advances, combined with the deregulation of the telecommunication market and the proliferation of the internet, have created a highly competitive environment for communication service prividers. Pricing is no longer as simple as picking an appropriate model for a particular contract. There is a real need for a book that explains the provision of new services, the relation between pricing and resource allocation in networks; and the emergence of the internet and how to price it. Pricing Communication Networks provides a framework of mathematical models for pricing these multidimensional contracts, and includes background in network services and contracts, network techonology, basic economics, and pricing strategy. It can be used by economists to fill in the gaps in their knowledge of network services and technology, and for engineers and operational researchers to gain the background in economics required to price communication services effectively. * Provides a broad overview of network services and contracts * Includes a primer on modern network technology and the economic concepts relevant to pricing and competition * Includes discussion of mathematical models of traffic flow to help describe network capability and derive pricing strategies * Includes coverage of specialist topics, such as regulation, multicasting, and auctions * Illustrated throughout by detailed real examples * Suitable for anyone with an understanding of basic calculus and probability Primarily aimed at graduate students, researchers and practitioners from electrical engineering, computer science, economics and operations research Pricing Communication Networks will also appeal to telecomms engineers working in industry.
