Internet-based Quality of Service: Everyone wants it, a fortune has been spent pursuing it, but for most network professionals, it's still something of a mystery. In Internet QoS, Lucent Bell Labs researcher Zheng Wang demystifies QoS once and for all. Wang, who's been doing Internet-related research for 14 years, knows the subject as well as anyone (he holds multiple patents in the field). He starts with an overview of the big picture: why the Internet in its raw form does such a poor job at providing consistent service quality, and why activating allocating resources isn't enough, you have to organize them more efficiently -- which in turn requires new tools, protocols, and standards. The book contains a detailed introduction to Integrated Services, the first Internet QoS architecture, and Differentiated Services, a reasonably simple, coarse method for specifying levels of service. Next, Wang introduces Multiprotocol Label Switching (MPLS): concepts, architecture, and label distribution protocols. Finally, he focuses on Internet traffic engineering: the evolving techniques service providers use to optimize resource utilization in their networks, avoiding congestion. By the time you've finished this concise, cleanly written book, you'll clearly understand QoS -- and how to deliver it.(Bill Camarda)--Bill Camarda is a consultant, writer, and web/multimedia content developer with nearly 20 years' experience in helping technology companies deploy and market advanced products and services.
