This book addresses the multiple technical aspects of thedistribution of synchronization in new generation telecommunicationnetworks, focusing in particular on synchronous Ethernet andIEEE1588 technologies. Many packet network engineers struggle withunderstanding the challenges that precise synchronizationdistribution can impose on networks. The usual “why”,“when” and particularly “how” can causeproblems for many engineers. In parallel to this, some othermarkets have identical synchronization requirements, but with theirown design requirements, generating further questions. This bookattempts to respond to the different questions by providingbackground technical information. Invaluable information on stateof-the-art packet network synchronization and timing architecturesis provided, as well as an unbiased view on the synchronizationtechnologies that have been internationally standardized overrecent years, with the aim of providing the average reader (who isnot skilled in the art) with a better understanding of this topic.The book focuses specifically on synchronous Ethernet and IEEE 1588PTP-based technologies, both key developments in the world ofsynchronization over the last 10 years. The authors address theneeds of engineers and technical managers who are struggling withthe subject of synchronization and provide an engineering referencefor those that need to consider synchronization in NGN. The marketapplications that are driving the development of packet networksynchronization and timing architectures are also discussed. Thisbook provides a wide audience with everything they need to knowwhen researching, implementing, buying and deploying packetsynchronization architectures in telecommunication networks. Contents 1. Network Evolutions, Applications and Their SynchronizationRequirements. 2. Synchronization Technologies. 3. Synchronization Network Architectures in Packet Networks. 4.

A common sense of time among the elements of a distributed measurement and control system allows the use of new techniques in solving problems with complex synchronization requirements or arising from the interaction of many sensors and actuators. Such a common sense of time may be accomplished using the standard IEEE 1588-2002 to synchronize real-time clocks integral to each component of the system. IEEE 1588, expands the performance capabilities of Ethernet networks so that they become relevant for measurement and control; this monograph embodies the first unified treatment of the associated technology, standards and applications. Readers will gain understanding of the technological context of IEEE 1588 and its role in a variety of application settings. To engineers this monograph provides detailed discussion of the complex features of the standard. Together with the essential material on best practice and implementation issues, these provide invaluable assistance in the design of new applications.

Random SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks. The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the saturation zone. In this context, game theory has demonstrated his ability to lead the network to a more efficient equilibrium. This, we were led to propose our model code set that formalizes the behavior of nodes during transmission within SALOHA networks and CSMA respectively.

Nowadays, the Internet has become an irreplaceable tool, feeding us information about new innovations and the evolution of the markets relating to all human activities. What the Internet lacks, though, is a guiding narrative thread, which is crucial to understand the evolution from old technologies into the technologies available today, and to benefit from the commentary which could elucidate that process of evolution. In spite of its inherent richness, no encyclopedia can constitute the one and only referential information source. The actors involved also have the right to be heard: all those who have devoted their working lives to the collective effort of edifying networks can, of course, present their personal views about the evolution of the world of telecommunications, and thus provide invaluable testimony to companies in this area who can make use of it. It is that approach which is adopted in this book. Whilst the primary objective of this book is to encourage SMEs to use digital technologies, and help them to organize with that goal in mind, it has proved necessary to describe the transformations currently under way in the field of networks, and to outline the efforts to obtain a competitive edge in terms of clerical applications, compare the various techniques that are available for high data rate communications, and touch upon the advent of the "Internet of Things", cloud computing and various new multimedia technologies. All in all, this book should help companies – particularly SMEs – to garner overall information about the current movement in the area of networking, and assist them in putting in place and managing their own communications systems.

The complete guide to timing and synchronization in advanced service provider networks and enterprise applications As networks have advanced, so has the need for precise timing and synchronization--including highly accurate phase synchronization. Without it, networks become increasingly vulnerable to outages, data loss events, and inefficiencies that can be notoriously difficult to diagnose. 5G telecom networks have especially stringent requirements, but they also apply to a growing number of enterprise applications in finance, factory automation, IoT, media, and beyond. Synchronizing 5G Mobile Networks is the definitive, comprehensive guide to all aspects of timing and synchronization. Drawing on extensive experience developing and implementing timing and synchronization systems, three leading experts cover standards, protocols, clock design, architecture, solution design, deployment tradeoffs, day-to-day operations, troubleshooting, and more. This book will be valuable to professionals with diverse backgrounds, even those with no timing or synchronization experience.

We present queueing-based algorithms to calculate the bandwidth required for a video stream so that the three main Quality of Service constraints, i.e., end-to-end delay, jitter and packet loss, are ensured. Conversational and streaming video-based applications are becoming a major part of the everyday Internet usage. The quality of these applications (QoS), as experienced by the user, depends on three main metrics of the underlying network, namely, end-to-end delay, jitter and packet loss. These metrics are, in turn, directly related to the capacity of the links that the video traffic traverses from its source to destination. The main problem that this book addresses is how much bandwidth we should allocate on the path from source to destination of a video traffic flow such that the end-to-end delay, jitter and packet loss of the video packets are within some expected required bounds.

This book deals with the field of identification and sensors, more precisely the possibility of collecting information remotely with RF waves (RFID). The book introduces the technology of chipless RFID starting from classical RFID and barcode, and explores the field of identification and sensors without wire, without batteries, without chip, and with tags that can even be printed on paper. A technique for automatic design of UHF RFID tags is presented , aiming at making the tags as insensitive as possible to the environment (with the ability to increase the reading range reliability), or, conversely, making them sensitive in order to produce sensors, meanwhile keeping their unique ID. The RFID advantages are discussed, along with its numerous features, and comparisons with the barcode technology are presented. After that, the new chipless RFID technology is introduced on the basis of the previous conclusions. Original technological approaches are introduced and discussed in order to demonstrate the practical and economic potential of the chipless technology.

This book reviews the concept of Software-Defined Networking (SDN) by studying the SDN architecture. It provides a detailed analysis of state-of-the-art distributed SDN controller platforms by assessing their advantages and drawbacks and classifying them in novel ways according to various criteria. Additionally, a thorough examination of the major challenges of existing distributed SDN controllers is provided along with insights into emerging and future trends in that area. Decentralization challenges in large-scale networks are tackled using three novel approaches, applied to the SDN control plane presented in the book. The first approach addresses the SDN controller placement optimization problem in large-scale IoT-like networks by proposing novel scalability and reliability aware controller placement strategies. The second and third approaches tackle the knowledge sharing problem between the distributed controllers by suggesting adaptive multilevel consistency models following the concept of continuous Quorum-based consistency. These approaches have been validated using different SDN applications, developed from real-world SDN controllers.
