"This book is an invaluable resource for anyone interested in understanding the rationale and technology driving the evolution of the Web. I especially liked the way the authors tie together the various elements and protocols that make up content distribution systems over the Web." --Prof. Dr. Ralf Steinmetz, Head of Multimedia Communications Lab (KOM), Darmstadt University of Technology, Germany"Finally, there is a comprehensive and authoritative text on all aspects of content delivery networking, the true Intelligent Network of the Internet! I will certainly use this book in teaching graduate students." --Igor Faynberg, Technical Manager, Internet Standards, Bell Labs/Lucent Technologies, and Adjunct Professor of Computer Science, Stevens Institute of Technology"This book closes a major gap in current literature: it gives a comprehensive overview of all aspects of content delivery networks. It is easy to read, yet provides an in-depth understanding of the algorithms and communication protocols involved." --Prof. Dr. Wolfgang Effelsberg, University of Mannheim, Director, Computer Networks and Multimedia Technology Research Group
