Why implement service quality? Is it possible to ensure reliable service quality in multi-service IP networks? Which technologies help in making end-to-end quality of service a realistic business proposition? In "Implementing Service Quality in IP Networks," Vilho Risnen answers these questions and more. The author discusses the business drivers for multi-service IP networks from various different angles. He defines service quality, explains how to estimate and measure the end-user experience and discusses different ways of conveying service quality requirements to the network. Turning theory into practice, he uses Service Level Agreements (SLAs) as a framework for discussing inter-domain management and measurement of multi-service IP networks. Bandwidth broker assisted signalling is presented as an evolutionary step towards dynamic SLAs. Finally, a case study describing service quality support in an IP-based Radio Access Network (RAN) illustrates the techniques introduced in the book. Features: A service-centred approach to Quality of Service A 'system solution' for end-to-end service support An overview of QoS support technologies such as Differentiated Services (DiffServ), Multi-Protocol Label Switching (MPLS), traffic engineering, policy management, and SLAs Management solutions for network administrators Application in an IP-based wireless Radio Access NetworkA practical guide which will appeal to all network planners, managers, administrators and designers, as well as students on network management courses, this book demonstrates that implementing service quality in IP networks is a realistic business goal. "IP-based services and networks are already dominatingfixed services and will do the same in mobile within a few years time. In order to improve network utilization, manage service levels for end-users and between operators QoS is absolutely necessary.

Never before have communications technologies moved so quickly or changed so dynamically. The use of standard computing hardware and the influence of the Internet have lead to so-called next-generation networks. This book explores the evolution to the new world of 'Next-Generation Networks' and services: The telecommunications industry is facing one of its toughest challenges yet - the transition from circuit-switched to packet-switched voice networks. Companies need to seize the opportunity of the convergence of voice networks and the Internet to deliver exciting and useful services. "Next Generation Network Services" explains technologies that have, and will influence this change, and brings together technologies such as softswitching, IP telephony, network directories and application frameworks. Features: Fixed and wireless telephony. Internet technologies. Standards. Understanding business goals in implementing a next-generation telecommunications network. A forward look at future services via telecommunications networks and their implications. Network-based services and hosted solutions for customers from computer telephony integration (CTI) through to the rise of the Application Service Provider.This book will interest telecommunications professionals as well as engineers who are working on current circuit-switched and future networks.

Network Information Service - The Network Information Service or NIS is Sun Microsystems' "Yellow Pages" (YP) client-server directory service protocol for distributing system configuration data such as user and host names between computers on a computer network.

Denial-of-service attack - A denial-of-service attack (also, DoS attack) is an attack on a computer system or network that causes a loss of service to users, typically the loss of network connectivity and services by consuming the bandwidth of the victim network or overloading the computational resources of the victim system.

Directory service - A directory service is a software application—or a set of applications—that stores and organizes information about a computer network's users and network shares, and that allows network administrators to manage users' access to the shares. Additionally, directory services act as an abstraction layer between users and shared resources.

Banyan VINES - Banyan VINES (for Virtual Integrated NEtwork Service) was a computer network operating system and the set of computer network protocols it used to talk to client machines on the network. The Banyan company based the VINES operating system on Unix, and the network protocols on the archetypical Xerox XNS stack.
