Optical switching / par El-Bawab, Tarek S. Publication : [S.l.] : Springer, 2006 . 450 p. ; , Optical Switching is the most comprehensive and up to date reference book on its subject. After three decades of research and development efforts, optical switching has started to be deployed in cutting-edge networking initiatives. The optical devices, optical networks, and telecommunications/data networking communities are in need of a reference book that compiles diverse optical switching research, from device technologies to system and network architectures, into one properly structured volume. This book provides such a service to these communities. The book is structured into three parts. The first part provides the foundation for understanding the potential role of optical switching in communication networks. The second part is focused on optical switching technologies and on devices based upon them. Theories, operation principles, and fabrication techniques are discussed. The third part covers optical-switching fabrics, systems, and networks. Applications of optical switching in communication networks are discussed, involving optical circuit, packet, and burst switching. The chapters are self-contained with minimum overlap. They bring together academic and industrial contributions, analytical and descriptive treatments, and cover theories, experimentation, and practice. The material has been carefully coordinated to form a homogeneous manuscript having a progressive and logical development of ideas and concepts. The book embraces a number of distinctive innovations. Old and new terminologies are investigated, clarified, redefined where necessary, and used consistently throughout the entire volume. The treatment of the subject is original, not only in terms of comprehensive coverage, but also in terms of structure and organization.   24 cm.

Understanding intrusion detection through visualization / par Axelsson, Stefan. Publication : [S.l.] : Springer, 2005 . 145 p. ; , With the ever increasing use of computers for critical systems, computer security that protects data and computer systems from intentional, malicious intervention, continues to attract attention. Among the methods for defense, the application of a tool to help the operator identify ongoing or already perpetrated attacks (intrusion detection), has been the subject of considerable research in the past ten years. A key problem with current intrusion detection systems is the high number of false alarms they produce. Understanding Intrusion Detection through Visualization presents researchïɪħon why false alarms are, and will remain a problem; then appliesïɪħresults from the field of information visualization to the problem of intrusion detection. This approach promises to enable the operator to identify false (and true) alarms, while aiding the operator to identify other operational characteristics of intrusion detection systems. Thisïɪħvolume presents four different visualization approaches, mainly applied to data from web server access logs. 24 cm.

Video traces for network performance evaluation : a comprehensive overview and guide on video traces and their utilization in networking research / par Seeling, Patrick. Publication : [S.l.] : Springer, 2006 . 274 p. ; , Multimedia networking, especially the delivery video over the Internet, accounts for a large fraction of todayЀ™s and future computer networks. Working with actual video provides several challenges on different technical and social levels. Video traces - a representation of video data and video quality in textual format - present a different approach to facilitate studies with video traffic. Video Traces for Network Performance Evaluation provides a comprehensive introduction to video traces and their use in networking research. After first providing the basics of digital video and video coding, video traces are introduced, covering the metrics captured in the traces, the trace generation, as well as the statistical characteristics of the video characterized in the traces. Attention is then turned to the use of the video traces in networking research, examining the practical aspects of transporting video over Internet Protocol (IP) networks and the simulation of video transport using traces, including the simulations that incorporate the impact of transmission errors using offset distortion traces. Software tools and utilities that facilitate the use of video traces in network simulations and other video networking related software tools are also presented. 24 cm.
