Implementing Service Quality In Ip Networks

While more and more data is shifted from circuit-switched to packet-switched networks, the users of these networks expect a smooth, continuously unproblematic service (unrelated to the amount of data transported). Therefore, the reliability of a network as well as the satisfaction of its users relies largely on Quality of Service (QoS). Service quality through resource management in IP networks will ensure that sufficient resources are available to fulfil the delay of applications and packet loss requirements. This year several books on QoS from the angle of operators/engineers have been published HOWEVER, none of these titles tackle the management side of the problem. This book shows how to determine quality requirements of services, it discusses and considers the various means of allocating network resources and of supervising the service quality. Furthermore, it explores strategies for allocating network resources and their relation to revenue or operator utility as well as service allocation optimization. The book concludes with a Nokia case study that illustrates the previously mentioned concepts. Essential reading for networking professionals wishing to understand service quality management in IP networks, as well as students needing to understand principles and basic techniques of service quality management.

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.

IP has a major role in the evolution of networks and services. Issues relating to end-to-end network and service management which offers advanced services, are addressed in this book; making it a defining work on this topic.

Public and private networks will eventually be configured in such a way that all voice calls are routed using Internet protocols Reviews existing and emerging standards for voice over IP Provides detailed guidance on how to engineer an efficient VoIP network Discusses quality of service (QoS) enforcement techniques Shows how to prototype and test a network's performance

Internet Protocol (IP) networks have, for a number of years, provided the basis for modern communication channels. However, the control and management of these networks needs to be extended so that the required Quality of Service can be achieved. Information about new generations of IP networks is given, covering the future of pervasive networks (that is, networks that arealways present), Wi-Fi, the control of mobility and improved Quality of Service, sensor networks, inter-vehicle communication and optical networks.

Learn how to use service modelling to streamline and optimize processes! Information about customer needs, the technical composition of services, and service performance are fundamental to effective service management. Service modelling is a structured approach to utilizing this information to improve the way services are delivered. Consistent application of service modelling provides the automation of processes and timely access to information. Service Modelling presents a comprehensive, up-to-date overview of the topic, presented in the context both of business processes, and of requirements stemming from the need to manage network resources. Vilho Raisanen delivers a justification for service modelling, and explains state-of-the-art concepts, frameworks and standards in detail. Service Modelling: Provides a complete and illustrated overview of state-of-the-art concepts for service modelling, covering requirements and frameworks. Includes industry initiatives, conceptual frameworks, and the work of standardisation bodies. Discusses different modelling approaches, and the positioning of modelling of services in service management and in the wider operational context. Sets the modelling framework in the context of business drivers and modelling paradigms. Illustrates principles with real-world use cases, providing both fixed Internet and mobile network examples. Relates concepts to the work of TeleManagement Forum, giving practical examples throughout. Service Modelling: Principles and Applications is an invaluable guide to service modelling for telecommunications and data communications professionals, including vendors, operators, consultants, training organizations, service and content providers, system architects and engineers for IP-based services. Educational organizations, advanced undergraduate and graduate students on telecommunications and networking courses will also find this text invaluable.

New, attractive services for communications systems are versatile and promise to make the next generation of communications a success. Yet, as the systems grow more complex and diverse, so do the challenges of managing them. Service management derives from technologies used in fixed telephony systems and has evolved towards supporting packet-based services in an increasingly open environment. It is common belief that 3G (and later 4G) services will change the way we communicate and interrelate. The user will be put at centre stage and systems will be able to handle intelligent user profiles, proactive service selection, context-aware service provisioning and ubiquitous computing. Managing, charging for, and controlling these services render traditional business models inadequate and demand new solutions. Managing Mobile Services Covers challenges, solutions and technologies for implementing IP-based services in a mobile environment, with special attention to security, flexibility and charging. Discusses business models, service management architectures and standardization efforts. Considers requirements and characteristics of services, and service modelling. Includes two case studies illustrating the challenges, technologies and solutions involved with real-world service management. This book gives telecommunications/data engineers, operators and service providers as well as students and academics an in-depth understanding of the issues involved in implementing and managing new value-added services.
