A Practical Guide to Content Delivery Networks, Second Edition

Following in the tradition of its popular predecessor, A Practical Guide to Content Delivery Networks, Second Edition offers an accessible and organized approach to implementing networks capable of handling the increasing data requirements of an always on mobile society. Describing how content delivery networks (CDN) function, it provides an understanding of Web architecture, as well as an overview of the TCP/IP protocol suite.

The book reports on the development of the technologies that have evolved over the past decade as distribution mechanisms for various types of Web content. Using a structural and visual approach, it provides step-by-step guidance through the process of setting up a scalable CDN.

• Supplies a clear understanding of the framework and individual layers of design, including caching and load balancing
• Describes the terminology, tactics, and potential problems when implementing a CDN
• Examines cost-effective ways to load balance web service layers
• Explains how application servers connect to databases and how systems will scale as volume increases
• Illustrates the impact of video on data storage and delivery, as well as the need for data compression
• Covers Flash and the emerging HTML5 standard for video

Highlighting the advantages and disadvantages associated with these types of networks, the book explains how to use the networks within the Internet operated by various ISPs as mechanisms for effectively delivering Web server based information. It emphasizes a best-of-breed approach to building your network to allow for an effective CDN to be built on practically any budget. To help you get started, this vendor-neutral reference explains how to code Web pages to optimize the delivery of various types of media. It also includes examples of successful approaches, from outsourcing to do it yourself.

Good overall coverage of CDN technology (2006-09-26)

Gilbert Held has covered many aspects of CDN technology right from the basics to implementation. While i was more interested in finding out vendor specific details i found that this book covers some but not all of it.
I still think it's a good reference for Systems Architects, Dev Leads and IT Operations folks interested in off-loading content for large-scale e-commerce web sites.

Advanced Statistical Steganalysis (Information Security and Cryptography)

Steganography is the art and science of hiding information in inconspicuous cover data so that even the existence of a secret message is kept confidential, and steganalysis is the task of detecting secret messages in covers. This research monograph focuses on the role of cover signals, the distinguishing feature that requires us to treat steganography and steganalysis differently from other secrecy techniques. The main theoretical contribution of the book is a proposal to structure approaches to provably secure steganography according to their implied assumptions on the limits of the adversary and on the nature of covers. A further contribution is the emphasis on dealing with heterogeneity in cover distributions, crucial for security analyses. The author's work complements earlier approaches based on information, complexity, probability and signal processing theory, and he presents numerous practical implications. The scientific advances are supported by a survey of the classical steganography literature; a new proposal for a unified terminology and notation that is maintained throughout the book; a critical discussion of the results achieved and their limitations; and an assessment of the possibility of transferring elements of this research's empirical perspective to other domains in information security. The book is suitable for researchers working in cryptography and information security, practitioners in the corporate and national security domains, and graduate students specializing in multimedia security and data hiding.

Data Compression In Imaging (Synthesis Lectures on Image, Video, and Multimedia Processing)

Image and Video Data Compression using Spline and Quadtree: Applications of Spline and Quadtree in Data Compression

Compression techniques have played an important role in the world of telecommunication and multimedia systems. We present two new techniques of video data compression. First technique is based on spline approximation of intensity variations of each pixel individually in the sequence of frames. This technique yields very precise control of accuracy. The second technique gives more consideration to achieve higher compression ratio, and applies fitting to group of pixels at correlated spatial locations in the sequence of frames. The second technique can be incorporated at the motion compensation stage of existing video coding schemes e.g., MPEG-1/2. For compression of synthetic image data, we presented a new hybrid scheme based on quadtree decomposition and parametric line fitting. This scheme consists of two phases. In the first phase, the input image is partitioned into homogeneous and non-homogeneous using quadtree quadrants decomposition. In the second phase luminance variations of are fitted using parametric line. The work of this book should be especially useful to students and professionals in Computer Science, Computer Engineering and Telecommunication fields.

Excerpt: Arithmetic coding is a form of variable-length entropy encoding used in lossless data compression. Normally, a string of characters such as the words "hello there" is represented using a fixed number of bits per character, as in the ASCII code. When a string is converted to arithmetic encoding, frequently-used characters will be stored with fewer bits and not-so-frequently occurring characters will be stored with more bits, resulting in fewer bi...
