"This book is by far the most comprehensive and orderly treatment of the subject. It is the work of experts with a wealth of both theoretical and practical experience with the subject and its connecting disciplines. It is an integral work... concepts and notation are at the same consistent level throughout the book. Quality of Service (QoS) is an absolutely critical part of any telecommunication services. This work fills a gap in the literature of what possibilities there are for satellites in providing global Internet services." Excerpted from the Foreword by Raymond L. Pickholtz, The George Washington University
Broadband Satellite Communications for Internet Access is a systems engineering methodology for satellite communication networks. It discusses the implementation of Internet applications that involve network design issues usually addressed in standard organizations. Various protocols for IP- and ATM-based networks are examined and a comparative performance evaluation of different alternatives is described. This methodology can be applied to similar evaluations over any other transport medium.
This book, suitable as a teaching text as well as a reference, covers:
-Satellite networks: technology, history and broadband communication satellites planned and launched into service.
-Trends Analysis: satellite networks covering physical, MAC, IP, transport layer protocols with an emphasis on TCP enhancements to account for fading, errors, noise, Doppler shifts and nomadic behavior.
-Quality of Service (QoS): end-to-end QoS model, framework and architectures including IntServ, DiffServ and MPLS traffic engineering for satellite IP networks, application QoS mapping.
-Satellite IP: design and implementation, DiffServ based QoS performance models for TCP and UDP traffic for GEO and MEO configurations.
-Interactive Multimedia over Satellite: TDMA and CDMA based return channel protocol models and analysis for DVB-RCS networks.
-Satellite ATM: analysis of fundamental questions (e.g. buffer requirements, TCP/ATM, efficiency, fairness, and multiple access models).
-International Standards: definitions, processes and agreed objectives for satellite IP and satellite ATM networks-ITU-R, ITU-T, IETF, ETSI, ATM Forum.
Whether you're a researcher, systems engineer, or a telecommunications/network specialist, Broadband Satellite Communications for Internet Access provides a comprehensive perspective on satellite networks. It addresses the end-to-end protocol stack, satellite design principles, QoS methodologies and international standards for building satellite network systems for multimedia applications.


Introduction To Satellite Oceanography

Satelli te oceanography, as the term is used in this book, is a generic term that means application of the technology of aerospace electromagnetic remote sensing to the study of the oceans. The key words here are "application of technology **. to the study of the oceans." The goal is to learn more about our planet's hydrosphere. As such, remote sensing technology is another tool in the oceanographer's sea bag, just like a bathythermograph or a plankton net. But is a whole book necessary if remote sensing is just another tool? While it is true that no one has written a whole book on plankton nets, volumes have been written about what is found in those nets. Today's state-of-the-art measurements from spacecraft or aircraft first must be interpreted in terms of their physics; then the interpretations must be understood in terms of oceanic processes. This is not materially different from the analogy to Ii plankton net; marine biolo- gists still argue about what didn't get caught in the net.


National Government And Control Of The Internet

Over the last decade, the Internet has transformed how information can be made available-it is now used to transfer information about things as varied as financial transactions and celebrity gossip and to link and coordinate activities between otherwise isolated people, from protest groups to lonely hearts. This unprecedented ease of access to a wealth of information and contacts presents a challenge to national governments who wish to control and restrain some of this activity.
In recent years, Internet control has become one of the major indicators to assess the balance between freedom and security in democracies. This book explores and compares how, why, and to what extent, national governments decide to control the Internet and how this impacts on crucial socio-economic activities and fundamental civil rights. The author provides detailed studies on the US, Germany, Italy and further case studies on Brazil, Canada, India, the Netherlands, South Africa and Switzerland, to address topics such cyber terrorism, the protection of information infrastructure, and the impact on individual privacy and freedom of speech.
This is the first cross-country, comparative study on the issue of Internet control. It will be of interest to international relations scholars and students, and particularly those with an interest in the Internet.
