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 and 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.

Network security has become the latter-day equivalent of oxymoronic
terms like “jumbo shrimp” and “exact estimate.” Newspaper headlines are
routinely peppered with incidents of hackers thwarting the security put
forth by the government and the private sector. As with any new
technology, the next evolution of network security has long languished
in the realm of science fiction and spy novels. It is now ready to step
into the reality of practical application.

In Biometrics for Network Security,
biometrics security expert Paul Reid covers a variety of biometric
options, ranging from fingerprint identification to voice verification
to hand, face, and eye scanning. Approaching the subject from a
practitioner’s point of view, Reid describes guidelines, applications,
and procedures for implementing biometric solutions for your network
security systems.

Coverage includes:

• An introduction to authentication technologies and biometrics
• Dealing with privacy issues
• Biometric technologies, including finger, hand geometry, handwriting, iris, retina, voice, and face
• Security concerns related to biometrics, including attempts to spoof or fake results
• Deployment of biometric security systems, including vendor selection and roll out procedures
• Real-life case studies

For
security, system, and network administrators and managers, as well as
anyone who is interested in the application of cutting-edge biometric
technology, Biometrics for Network Security will prove an indispensable addition to your library!

Among the many functions
that networking technologies permit is the ability for organizations to
easily and securely communicate with branch offices, mobile users,
telecommuters, and business partners. Such connectivity is now vital to
maintaining a competitive level of business productivity. Although
several technologies exist that can enable interconnectivity among
business sites, Internet-based virtual private networks (VPNs) have
evolved as the most effective means to link corporate network resources
to remote employees, offices, and mobile workers. VPNs provide
productivity enhancements, efficient and convenient remote access to
network resources, site-to-site connectivity, a high level of security,
and tremendous cost savings.

“Professor Nassar has an uncanny ability to demystify the complexities
of telecommunications systems engineering.” Dale N. Hatfield, former
chief, Office of Engineering and Technology, Federal Communications
Commission

Book Provides a Worthy Telecomm Course:
Continuing
its Demystifying Technology series, LLH Technology Publishing’s
Telecommunications Demystified by Carl R. Nassar provides a
wide-ranging tutorial on theory and practical issues using the
requisite math and equations. This book does not provide primarily a
circuit-design or even a system-level, block-diagram treatment;
instead, it seeks to explain the underlying principles, problems,
techniques, and constraints of standard telecommunication functions.
The book covers networks, source coding/decoding, modulators and
demodulators, channel coding and decoding, trellis-coded modulation,
filtering and equalizers, signal detection and estimation, and error
detection and correction, among other topics.

I won’t mislead
you and say this book is an easy read or a quick read. If you plan to
get the most out of it, you need to pay attention and follow the
equations and derivations, which include integrals, differentials,
matrices, and more. Fortunately, the author clearly explains the
transitions from one equation to the next without those fear-inducing
phrases, such as “we can see,” “the derivation is left as an exercise
to the reader,” and “it can be shown.” If you want to increase your
understanding of the issues and answers in digital-communications
systems and some analog systems, this book should help. It also
includes a CD-ROM with a searchable version of the book and tutorials
that support topics in the text.
