Current estimates and measurements predict that Internet traffic will continue togrow for many years to come. Driving this growth is the fact that the Internet hasmoved from a convenience to a mission-critical platform for conducting andsucceeding in business. In addition, the provision of advanced broadband servicesto end users will continue to cultivate and prolong this growth in the future. As aresult, there is a great demand for gigabit/terabit routers and switches (IP routers,ATM switches, Ethernet switches) that knit together the constituent networks ofthe global Internet, creating the illusion of a unified whole. These switches/routersmust not only have an aggregate capacity of gigabits/terabits coupled withforwarding rates of billions of packets per second, but they must also deal withnontrivial issues such as scheduling support for differentiated services, a widevariety of interface types, scalability in terms of capacity and port density, andbackward compatibility with a wide range of legacy packet formats and routingprotocols.This edited book is a modest attempt to provide a comprehensive venue foradvancing, analyzing, and debating the technologies required to address the abovementionedchallenges, such as scaling the Internet and improving its capabilities.In particular, this book is a collection of chapters covering a wide range of aspectspertaining to the design, analysis, and evolution of high-performance Internetswitches and routers. Some of the topics include switching fabrics, networkprocessors, optical packet switching and advanced protocol design. The authors ofthese chapters are some of the leading researchers in the field. As a result, it is ourhope that this book will be perceived as a valuable resource to as many readers aspossible including university professors and students, researchers from industry,and consultancy companies. |
