Riassunto

An oft-repeated adage among telecommunication providers goes, There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can t do all ve, at least do the rst three. Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

Dalla quarta di copertina

The Internet is a critical infrastructure supporting our information-based society. Our dependence on this infrastructure is similar to our dependence on the world's power grids and global transportation systems. Failures of the network infrastructure or major applications running on it can have an enormous financial and social cost, with serious consequences to the organizations and consumers that depend on these services.

Supporting reliable networks and networked application services involves some of the most complex engineering and operational challenges that are dealt with in any industry. This unique and valuable guide addresses the challenges faced by service providers and the approaches they use to deliver reliable services to their users. The book offers a systematic, inter-disciplinary approach and coverage of practical problems arising in real, operational deployments. Leading practitioners and researchers present their unique perspectives on the subject matter, and provide "best practices" to help translate ideas into practice.

Topics and features:

• Introduces the challenges of building reliable networks and services, presenting an overview of the structure of a large ISP backbone network
• Examines network reliability modeling and network planning, covering router elements and their failure modes, and providing a theoretical grounding in performance and reliability modeling
• Investigates inter-domain reliability and overlay networks, presenting existing solutions and possible future research directions, and reviewing how overlay applications can increase network resilience
• Explores the critical function of network configuration management, and considers auditing from the perspective of bottom-up, network-wide configuration validation
• Discusses network measurement, with a focus on reliability and performance monitoring, covering both data-plane and control-plane measurements

• Covers network management systems and the tasks involved in supporting day-to-day operations of an IP network, including fault diagnosis, trouble-shooting, security management, and disaster recovery
• Presents an approach to the design and development of reliable network application software, and provides a comprehensive overview of server capacity and performance engineering

This comprehensive text/reference on reliable Internet services and applications is suitable for an advanced undergraduate or graduate course, and will be of value to researchers seeking to understand the challenges faced by service providers and to identify areas that are ripe for research. The guidebook will be particularly useful to practitioners who want to broaden their understanding of the field, and/or to deepen their knowledge of the fundamentals.
