Scalable Continuous Media Streaming Systems

Continuous media streaming systems will shape the future of
information infrastructure. The challenge is to design systems and
networks capable of supporting millions of concurrent users. Key to
this is the integration of fault-tolerant mechanisms to prevent
individual component failures from disrupting systems operations.
These are just some of the hurdles that need to be overcome before
large-scale continuous media services such as video-on-demand can
be deployed with maximum efficiency.

The author places the subject in context, drawing together
findings from the past decade of research whilst examining the
technology's present status and its future potential. The
approach adopted is comprehensive, covering topics - notably
the scalability and fault-tolerance issues - that previously have
not been treated in depth.

* Provides an accessible introduction to the technology,
presenting the basic principles for media streaming system design,
focusing on the need for the correct and timely delivery of
data.

* Explores the use of parallel server architectures to tackle the
two key challenges of scalability and fault-tolerance.

* Investigates the use of network multicast streaming algorithms
to further increase the scalability of very-large-scale media
streaming systems.

* Illustrates all findings using real-world examples and case
studies gleaned from cutting-edge worldwide research.

Combining theory and practice, this book will appeal to industry
specialists working in content distribution in general and
continuous media streaming in particular. The introductory
materials and basic building blocks complemented by amply
illustrated, more advanced coverage provide essential reading for
senior undergraduates, postgraduates and researchers in these
fields.
