Develop cost-effective, long-term solutions to your network traffic control problems. Even if you can find the money to do it, overengineering your network will not solve your traffic flow problems. As the authors of this groundbreaking guide clearly demonstrate, the best long-term solution to network congestion and bottlenecks can be found in a set of Quality of Service (QoS) architectures, policies, and technologies known as differentiated Classes of Service (CoS). Quality of Service is a valuable working resource for technical managers charged with solving the problem of how to handle the exploding volume of traffic on their companies' networks. The authors explore the roots of the current network traffic control crisis and they provide a realistic assessment of the gamut of standard, new, and emerging QoS/CoS technologies. They consider all crucial, design, cost, and support issues surrounding quality of service deployment for all types of networks, including intranets and multimedia networks. And they provide managers with a rational framework for finding the most cost-effective QoS/CoS solutions to their organizations' long-term networking goals. Key technical issues covered include: * Queuing disciplines, traffic shaping, and admission control techniques * Quality and differentiation hooks found in TCP/IP * Getting the most out of Frame Relay and ATM technologies * QoS/CoS techniques for dial-up services * Integrated Services Architecture and RSVP.

The complete resource for understanding and deploying IP quality of service for Cisco networks Learn to deliver and deploy IP QoS and MPLS-based traffic engineering by understanding: QoS fundamentals and the need for IP QoS The Differentiated Services QoS architecture and its enabling QoS functionality The Integrated Services QoS model and its enabling QoS functions ATM, Frame Relay, and IEEE 802.1p/802.1Q QoS technologies and how they work with IP QoS MPLS and MPLS VPN QoS and how they work with IP QoS MPLS traffic engineering Routing policies, general IP QoS functions, and other miscellaneous QoS information Quality-of-service (QoS) technologies provide networks with greater reliability in delivering applications, as well as control over access, delay, loss, content quality, and bandwidth. IP QoS functions are crucial in today's scalable IP networks. These networks are designed to deliver reliable and differentiated Internet services by enabling network operators to control network resources and use. Network planners, designers, and engineers need a thorough understanding of QoS concepts and features to enable their networks to run at maximum efficiency and to deliver the new generation of time-critical multimedia and voice applications. "IP Quality of Service" serves as an essential resource and design guide for anyone planning to deploy QoS services in Cisco networks. Author Srinivas Vegesna provides complete coverage of Cisco IP QoS features and functions, including case studies and configuration examples. The emphasis is on real-world application-going beyond conceptual explanations to teach actual deployment. "IP Quality of Service" is written for internetworking professionals who are responsible for designing and maintaining IP services for corporate intranets and for service provider network infrastructures. If you are a network engineer, architect, manager, planner, or operator who has a rudimentary knowledge of QoS technologies, this book will provide you with practical insights on what you need to consider when designing and implementing various degrees of QoS in the network. Because incorporating some measure of QoS is an integral part of any network design process, "IP Quality of Service" applies to all IP networks-corporate intranets, service provider networks, and the Internet.

Quality of Service (QoS) is a standards effort to provide consistent levels of service despite delivery problems. Providing students with an understanding of the technologies and techniques that will enable Internet QoS, this book is for courses in network management.

Guaranteeing performance and prioritizing data across the Internet may seem nearly impossible because of an increasing number of variables that can affect and undermine service. But if you're involved in developing and implementing streaming video or voice, or other time-sensitive Internet applications, you understand exactly what's at stake in establishing Quality of Service (QoS) and recognize the benefits it will bring to your company. What you need is a reliable guide to the latest QoS techniques that addresses the Internet's special challenges. Internet QoS is it-the first book to dig deep into the issues that affect your ability to provide performance and prioritization guarantees to your customers and users! This book gives a comprehensive view of key technologies and discusses various analytical techniques to help you get the most out of network resources as you strive to make, and adhere to, meaningful QoS guarantees.* Includes valuable insights from a Bell Labs engineer with 14 years of experience in data networking and Internet protocol design.* Details the enhancements to current Internet architectures and discusses new mechanisms and network management capabilities that QoS will require. * Focuses on the four main areas of Internet QoS: integrated services, differentiated services, MPLS (Multiprotocol Label Switching), and traffic engineering.

Der Datenverkehr in lokalen und globalen Datennetzwerken nimmt ständig zu. Quality of Service zu bieten, ist deshalb eine der vordringlichsten Aufgaben der Kommunikationsindustrie. Eine praxisnahe Einführung in die QoS-Implementierung bietet diese topaktuelle Buch, das auch neue Steuerungstechniken für die nächste Generation der Multimedia-Netze erläutert. Theoretische Forschungsergebnisse und Beispiele aus der ingenieurtechnischen Praxis werden gleichermaßen berücksichtigt.

Routing and Quality-of-Service in Broadband LEO Satellite Networks describes mechanisms for supporting Quality-of-Service (QoS) strategies that consider properties of low earth orbit satellite networks and their effects on link handover. A graph model representing the dynamic topology of a satellite constellation is introduced based on a new parameter, lifetime. Novel routing and resource reservation algorithms as well as connection admission control strategies are proposed to minimize the handover blocking probability while maintaining QoS requirements. The author also discusses the roles of satellites in an all-IP mobile network architecture and the problems of mobility, QoS provisioning, and routing. This work will be of particular interest to researchers and professionals working on mobility networking in next generation networks.
