Tutorial #1 Tutorial type: full-day Author:James P. G. Sterbenz, University of Kansas Title:High-Speed Networking: A Systematic Approach to High-Bandwidth Low-Latency Communications Description: This tutorial presents a comprehensive introduction to all aspects of high-speed networking, based on the book High-Speed Networking: A Systematic Approach to High- Bandwidth Low-Latency Communication, James P.G. Sterbenz and Joseph D. Touch, John Wiley, 2001. The target audience includes computer scientists and engineers who may have expertise in a narrow aspect of high-speed networking (such as switch design), but want to gain a broader understanding of all aspects of high-speed networking and the impact that their designs have on overall network performance. This tutorial is not about any particular protocols and standards, but is rather a systemic and systematic approach to the principles that guide the research and design of high-speed networks, protocols, and applications. The network is a complex system of systems, and high-speed networking does not result from the design of individual components or protocols in isolation. Thus, this tutorial presents a systemic approach to high-speed networks, where the goal is to provide high bandwidth and low latency to distributed applications, and to deal with the high bandwidth-x-delay product that results from high-speed networking over long distances. A set of fundamental axioms is presented (Know the past present and future, Application primacy, High-performance paths, Limiting constraints, and Systemic optimisation), followed by the major topics: Network architecture and topology Network control and signalling Communication links Switches and routers End systems End-to-end protocols Networked applications A set of design principles are defined and applied to each of the topics: 1. Selective optimisation 2. Resource tradeoffs 3. End-to-end arguments 4. Protocol layering 5. State management 6. Control mechanism latency 7. Distributed data 8. Protocol data unit structure A set of design techniques (scaling time and space, masking the speed of light, specialised hardware implementation, parallelism and pipelining, data structure optimisation, cut-through and remapping) are introduced and applied as appropriate.
