In this book, focuses on the world of the ISP and in particular on the efficiency of their network operation and on the QoS that they (aim to) provide. Structures the book into four parts, namely the ISP market, network architecture, interconnection issues, and traffic and network engineering. In that way he situates descriptions of the technology issues and emerging solutions in their proper …

The growing interest in PGPRs emerges from the wish to shed more light on a complex and fascinating biological system and from the potential these organisms have to increase productivity of crop cultures. The strains that exhibit a specific desired characteristic are selected, tested, and then used as an element in agricultural practices, though so far these strategies have not been extensiv…

Cisco's routers may be the heart of the Internet and of corporate WANs, but it's a wellknown fact that the documentation that comes with them is often too abstruse to be useful. That's why network administrators, especially IP novices, will appreciate Cisco TCP/IP: Routing Professional Reference. Author Chris Lewis, a contributing editor for Network Computing magazine, successfully walks th…

Chapter 1, Upgrading Drupal, focuses on preparing a Drupal environment for running a high performance Drupal website. We will discuss upgrading Drupal 5.x to Drupal 6.x, creating backups of our site files and databases, running the Drupal Status report, upgrading contributed modules to their latest 6.x versions, and running update.php. We will also tweak our PHP settings using the Drupal setti…

Aging is a progressive accumulation of molecular damage in nucleic acids, proteins and lipids. The inefficiency and failure of maintenance, repair and turnover pathways is the main cause of age-related accumulation of damage, which is also the basis of all age-related diseases. Research in molecular gerontology is aimed at understanding the genetic and epigenetic regulation of molecular mec…

If you know anything about Linux you know that there are a lot of commands that accomplish the same task. To borrow the motto of Perl, a very popular scripting language with a long *nix history: “There’s more than one way to do it.” It is possible that no two people will do the same thing the same way, yet get the same results. In our book, we have used what we feel is the quickest and e…

Before we can delve into the world of conducting router and switch forensics on Cisco devices, we need to discuss what makes a network secure. Thirty years ago we were using mainframe computers and “security” meant nothing more than the fact that a physical wall separated the people who worked with the data from the machines storing that data. As PCs and local area networks (LANs) have ga…

This book incorporates into one reference source the material you will need to understand how Ethernet networks operate, the constraints and performance issues that affect their design and implementation, and how their growth and use can be managed both locally and as part of an enterprise network. Assuming readers have varied backgrounds in communications terms and technology, the first two c…

This book would serve as the most comprehensive source for an expert as well as a beginner in the area of CNT-reinforced metal matrix composites and nanotechnology. This book will also be beneficial for graduate students and researchers in nanotechnology, materials engineers, mechanical engineers, and chemical engineers.

This book treats qmail more as an architecture than a mail server, and from that perspective guides the reader through the installation, administration, customization, and deployment of a qmail-based server. The book begins with a quick, minimal, step-by-step walkthrough of a bare-bones qmail server, and then introduces and explains the basic design of the qmail architecture in easily understo…
