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.

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.

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.

This book, one of the first of its kind, presents mechanisms, protocols, and system architectures needed to attain end-to-end Quality of Service over heterogeneous wired and wireless networks in the Internet.

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.

The term Quality of Service, abbreviated QoS, refers to network resource control mechanisms. Quality of Service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. This book brings all of the elements of network quality of service (QoS) together in a single volume, saving the reader the time and expense of making multiple purchases. It introduces network QoS, explains the basics, describes the protocols, and discusses advanced topics, by the best and brightest experts in the field. It is a quick and efficient way to bring valuable content together from leading experts in the field while creating a one-stop-shopping opportunity for customers to receive the information they would otherwise need to round up from separate sources.

Excellence in customer service is the hallmark of success in service industries and among manufacturers of products that require reliable service. But what exactly is excellent service? It is the ability to deliver what you promise, say the authors, but first you must determine what you can promise. Building on seven years of research on service quality, they construct a model that, by balancing a customer's perceptions of the value of a particular service with the customer's need for that service, provides brilliant theoretical insight into customer expectations and service delivery. For example, Florida Power & Light has developed a sophisticated, computer-based lightening tracking system to anticipate where weather-related service interruptions might occur and strategically position crews at these locations to quicken recovery response time. Offering a service that customers expect to be available at all times and that they will miss only when the lights go out, FPL focuses its energies on matching customer perceptions with potential need. Deluxe Corporation, America's highly successful check printer, regularly exceeds its customers' expectations by shipping nearly 95% of all orders by the day after the orders were received. Deluxe even put U.S. Postal Service stations inside its plants to speed up delivery time. Customer expectations change over time. To anticipate these changes, Metropolitan Life Insurance Company regularly monitors the expectations and perceptions of their customers, using focus group interviews and the authors' 22-item generic SERVQUAL questionnaire, which is customized by adding questions covering specific aspects of service they wish to track. The authors' groundbreaking model, which tracks the five attributes of quality service -- reliability, empathy, assurance, responsiveness, and tangibles -- goes right to the heart of the tendency to overpromise. By comparing customer perceptions with expectations, the model provides marketing managers with a two-part measure of perceived quality that, for the first time, enables them to segment a market into groups with different service expectations.
