| Tutorial Contents |
The Internet, and in particular the World Wide Web (WWW), have become an integral part of people’s life. With the increase in popularity, however, users have to face more and more problems when using the Internet - high access delays, poor quality of service and unreliable services. This tutorial helps participants in understanding the reasons for these problems. It explains the challenges in making content available on the WWW, describes basic concepts and principles for improving the current situation and outlines possibilities for tapping into the huge potential of custom-tailored provisioning of converged services over the Internet.
The tutorial starts with a short summary of fundamental techniques and protocols for moving content on the Internet, followed by an introduction to fundamental web caching techniques. From there, the tutorial outlines the evolution from web caching towards a flexible and open architecture to support a variety of content-oriented services. Evolutionary steps include support for streaming media, systems for global request routing, and the design of APIs and protocols enabling value-added services, such as compression, filtering, or transformation. The tutorial also explains how the different components interact with each other and how they can be used to build complex content networks.
The participant will learn how the technology evolved from traditional web caching towards more sophisticated content services. The participant will get a better understanding of the key components in modern content networks and of the protocols that make the components interact with each other. Various examples will help the participant to better understand how this technology can be deployed and how it could help their business. All parts of the tutorial will have a mix of research and industry flavor, addressing seminal research concepts and looking at the technology from an industry angle. |
