Quality of Service (QoS) is continuously growing in importance in the telecommunications industry because competition is growing fiercer by the day. By drawing on 30 years of experience, William C. Hardy explains how to examine specific tools and techniques that he has developed for the measurement and evaluation of QoS and understand the underlying analysis perspectives and methodologies. Details the basic concepts of QoS, together with the methodologies for organizing, structuring, and carrying out analyses of QoS from scratch. Describes the atttributes of the telecommunications service that determine user perception of quality in non-technical terms. Discusses specific measures, measurement techniques and evaluation criteria for all of the factors that affect user perception of QoS. Addresses user concerns including: * Will I be able to get to the service when I want to use it? * How long does it take before I know a connection is being set up? * How good will voice sound over a connection? * Includes valuable tips for QoS analysis and the perspectives vital for describing QoS in ways that are useful and operationally meaningful. Whether you have a limited technical background or are a telecommunications professional this simple and straightforward approach will be an essential tool to understanding QoS.

Providing an efficient Quality of Service measurement model is a challenging problem in today's mobile computing and telecommunications networks. Currently, most of QoS techniques utilize service measurements that are collected by the network elements to evaluate the network performance. However, this process does not take into account the service performance from the clients perspective and might contradict with the Service Level Agreement. In order to overcome the limitations of service side QoS monitoring, a number of research studies have been conducted to present alternative architectures and algorithms for client side QoS service assessment in computer networks. The client side QoS approach gives the major role to the clients to evaluate the dedicated services through gathering the network measurements and reporting the necessary information. The service providers consider clients feedback to revise and resolve service performance issues. This model can be considered as a cooperative approach that provides a compromised service plan for both the service providers and the network clients to achieve a better network service performance. In this research, we study the tradeoffs between network side and client side QoS monitoring and present a client based architecture for the evaluation and prediction of service degradations in mobile networks. The client side approach should be capable of utilizing multi level service performance analysis in a scalable mobile network environment. The service performance analysis consists of three levels: service monitoring and evaluation, verifying and enhancing the network measurement accuracy, and performance prediction in single and multi hops networks. In addition, this approach should support short and long term service evaluation scenarios. The short term scenario gives the ability to service providers to react in a timely manner to the clients feedback to preserve a certain level of service performance. The long term scenario helps to clarify the service behavior by predicting the service degradation over the monitoring and evaluation sessions. Furthermore, this scenario allows the service providers to refine the degraded services and maintain the SLA.

Download QoS for Fixed and Mobile Ultra-Broadband Book in PDF, ePub and Kindle

Provides extensive coverage of standardized QoS technologies for fixed and mobile ultra-broadband networks and services—bringing together technical, regulation, and business aspects The Quality of Service (QoS) has been mandatory for traditional telecommunication services such as telephony (voice) and television (TV) since the first half of the past century, however, with the convergence of telecommunication networks and services onto Internet technologies, the QoS provision remains a big challenge for all ICT services, not only for traditional ones. This book covers the standardized QoS technologies for fixed and mobile ultra-broadband networks and services, including the business aspects and QoS regulation framework, which all will have high impact on the ICTs in the current and the following decade. QoS for Fixed and Mobile Ultra-Broadband starts by introducing readers to the telecommunications field and the technology, and the many aspects of both QoS and QoE (Quality of Experience). The next chapter devotes itself to Internet QoS, starting with an overview of numerous technology protocols and finishing with business and regulatory aspects. The next three chapters look at QoS in NGN and Future Networks, QoS for fixed ultra-broadband, and QoS for mobile ultra-broadband. The book also provides readers with in-depth accounts of services in fixed and mobile ultra-broadband; broadband QoS parameters, KPIs, and measurements; network neutrality; and the QoS regulatory framework. Comprehensively covers every aspect of QoS technology for fixed and mobile ultra-broadband networks and services, including the technology, the many regulations, and their applications in business Explains how the QoS is transiting from the traditional telecom world to an all-IP world Presents all the fundamentals of QoS regulation, as well as SLA regulation QoS for Fixed and Mobile Ultra-Broadband is an excellent resource for managers, engineers, and employees from regulators, ICT government organizations, telecommunication companies (operators, service providers), ICT companies, and industry. It is also a good book for students and professors from academia who are interested in understanding, implementation, and regulation of QoS for fixed and mobile ultra-broadband.

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.
