Internet Tomography: An Introduction to Concepts, Techniques, Tools and Applications

Internet tomography, introduced from basic principles through to techniques, tools and applications, is the subject of this book. The design of Internet Tomography Measurement System (ITMS) aimed at mapping the Internet performance profile spatially and temporally over paths between probing stations is a particular focus. ITMS design criteria addressed include: minimally-invasive, independent and autonomous, active or passive measurement, flexibility and scalability, capability of targeting local, regional and global Internet paths and underlying IP networks, compliance with the standardised performance methodologies and QoS metrics, e.g., those of the IETF IPPM Working Group. The book also features the use of Internet tomography measurement in modelling support, through network simulation and emulation, for real network and service design and analysis, and new service deployment; the exploration of spatial and temporal Internet performance variations by means of scenario-based analysis using real-time Internet performance data; aspects of Internet tomography in next generation wireless network -wireless NGN- architectures; and the role of ITMS in Service Level Agreement design, implementation and compliance.
