 Estimation and Control over Communication Networks

Estimation and Control over Communication Networks

Product Description

Rapid advances in communication technology have created the possibility of large-scale control systems with distribution of control tasks among several processors via communication channels. Such control systems may be distributed over large distances and may use large numbers of actuators and sensors. The possibility of such networked control systems has motivated the development of a new chapter in control theory in which control and communication issues are integrated, and all the limitations of communication channels are considered.

Although there is an emerging literature on this topic, this is the first book that attempts to present a systematic theory of estimation and control over communication networks. Using several selected problems of estimation and control over communication networks, the authors present and prove a number of results concerning optimality, stability, and robustness having practical significance for networked control system design. In particular, various problems of Kalman filtering, stabilization, and optimal control over communication channels are considered and solved. The results establish fundamental links among mathematical control theory, Shannon information theory, and entropy theory of dynamical systems.

Key features and topics of the work:

* Offers accessible but precise development of important mathematical models and results

* Covers estimation and stabilization of both linear and nonlinear systems

* Addresses limited capacity communication channels, noisy discrete channels, systems with disturbances, irregular transmission times, and switched sensors

* Presents state-of-the-art developments and cutting-edge results in the field

This essentially self-contained monograph offers accessible mathematical models and results for advanced postgraduate students, researchers, and practitioners working in the areas of control engineering, communications, information theory, signal processing, and applied mathematics who have an interest in the emerging field of networked control systems.

Storage Networks

Storage Networks

Rather than being based on a specific vendor offering, Storage Networks will appeal to any systems administrator, architect or manager with large data resources to manage.
Applicability of the technology to non-traditional IT buyers such as video and music production studios, medical diagnostic imaging and GIS applications is stressed. With the rapid adoption of digital processing for images and sound, storage networks have a great use outside of the data center. At the same time, the benefits of recoverability, performance and manageability required by the large glass house operation will benefit any storage network user. This book will appeal to both sets of readers.

Managing Internet Traffic

Network Congestion Control: Managing Internet Traffic

Product Description
As the Internet becomes increasingly heterogeneous, the issue of congestion control becomes ever more important.

In order to maintain good network performance, mechanisms must be provided to prevent the network from being congested for any significant period of time. Michael Welzl describes the background and concepts of Internet congestion control, in an accessible and easily comprehensible format.

Throughout the book, not just the how, but the why of complex technologies including the Transmission Control Protocol (TCP) and Active Queue Management are explained. The text also gives an overview of the state-of-the-art in congestion control research and an insight into the future.

Network Congestion Control:

  • Presents comprehensive, easy-to-read documentation on the advanced topic of congestion control without heavy maths.
  • Aims to give a thorough understanding of the evolution of Internet congestion control: how TCP works, why it works the way it does, and why some congestion control concepts failed for the Internet.
  • Explains the Chiu/Jain vector diagrams and introduces a new method of using these diagrams for analysis, teaching & design.
  • Elaborates on how the theory of congestion control impacts on the practicalities of service delivery.
  • Includes an appendix with examples/problems to assist learning.
  • Provides an accompanying website with Java tools for teaching congestion control, as well as examples, links to code and projects/bibliography.

This invaluable text will provide academics and researchers in computer science, electrical engineering and communications networking, as well as students on advanced networking and Internet courses, with a thorough understanding of the current state and future evolution of Internet congestion control. Network administrators and Internet service and applications providers will also find Network Congestion Control a comprehensive, accessible self-teach tool.

Designing Large-Scale LANs

Designing Large-Scale LANs

Large networks are complex systems, with many interdependent devices held together only by the strength of the network designer’s specifications. It takes a lot of knowledge–and a lot of time–to make sure that the capacity of links and nodes is neither wasted nor overloaded.

Designing Large-Scale LANs explains how the pieces of a large local area network (LAN) interoperate. A LAN, in author Kevin Dooley’s working definition here, is a building-size data network, or perhaps a campus-size system with a backbone running Gigabit Ethernet, ATM, or FDDI. Dooley does a good job of teaching his readers about, for example, the processing overhead involved in address translation or protocol tunneling, and why techniques like those should be used sparingly in a LAN that needs to be fast and efficient.

That said, Dooley spends a lot of time on network fundamentals. He explains subnet masking in his own rather appealing way, and takes readers on a tour of the Open Systems Interconnect (OSI) seven-layer model. He explains the function of split horizon and poison reverse in Routing Information Protocol (RIP), as well as the improvements more modern routing protocols make on RIP. In short, there’s an awful lot of background information here. Designers of big networks need to understand this stuff, but you might expect to see comparisons of competing vendors’ equipment here–there’s not enough of that–and less broad, conceptual information. On the other hand, you could do far worse than to study this book in preparation for a networking certification exam. –David Wall
