Internet QoS


Book Description

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.




Architectures for Quality of Service in the Internet


Book Description

Providing Quality of Service (QoS) in the Internet is currently the most ch- lenging topic for researchers, industry and network providers. Now, the only available service in the Internet is the best e?ort service, which assumes tra?c is processed as quickly as possible, but there is no guarantee as to timely or actual delivery. On the other hand, there is pressure to o?er new applications in the Internet (like VoIP, videoconferencing, on-line games, e-commerce, etc. ) but this requires some packet transfer guarantees from the network (e. g. , low packet transfer delay, low packet losses). To meet these requirements, new architectures for providing IP- based QoS in the Internet are proposed: Integrated Services (IntServ) and Di?erentiated Services (Di?Serv). However, these architectures need some enhancements to provide adequate solutions for resource mana- ment, signaling, tra?c engineering, tra?c handling mechanisms, etc. In the European research community, a number of projects inside the Fifth Framework Programme were addressed solving the above issues; among these AQUILA (Adaptive Resource Control for QoS Using an IP-Based Layered - chitecture), CADENUS (Creation and Deployment of End-User Services in P- mium IP Networks), and TEQUILA (Tra?c Engineering for Quality of Service in the Internet at Large Scale) are excellent examples. The main achievements from these projects are the prototypes for ?xed QoS IP networks. The extension of these proposed solutions into the wireless environment is the next step.

Quality of Service


Book Description

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 Competitive Internet Service Provider


Book Description

Due to the dramatic increase in competition over the last few years, it has become more and more important for Internet Service Providers (ISPs) to run an efficient business and offer an adequate Quality of Service. The Competitive Internet Service Provider is a comprehensive guide for those seeking to do just that. Oliver Heckmann approaches the issue from a system point of view, looking not only at running a network, but also at connecting the network with peering and transit partners or planning the expansion of the network. The Competitive Internet Service Provider: Offers an advanced reference on the topic, drawing on state-of-the art research in network technology. Clearly defines the criteria enabling ISPs to operate with the greatest efficiency and deliver adequate Quality of Service. Discusses the implications of the future multiservice Internet and multimedia applications such as Voice over IP, peer-to-peer, or network games. Delivers a comparative evaluation of different feasible Quality of Service approaches. Explores scientific methods such as queuing theory, network calculus, and optimization theory. Illustrates concepts throughout with mathematical models and simulations. This invaluable reference will provide academic and industrial researchers in the field of network and communications technology, graduate students on telecommunications courses, as well as ISP managers, engineers and technicians, equipment manufacturers and consultants, with an understanding of the concepts and issues involved in running a successful ISP.




Networks on Chip


Book Description

As the number of processor cores and IP blocks integrated on a single chip is steadily growing, a systematic approach to design the communication infrastructure becomes necessary. Different variants of packed switched on-chip networks have been proposed by several groups during the past two years. This book summarizes the state of the art of these efforts and discusses the major issues from the physical integration to architecture to operating systems and application interfaces. It also provides a guideline and vision about the direction this field is moving to. Moreover, the book outlines the consequences of adopting design platforms based on packet switched network. The consequences may in fact be far reaching because many of the topics of distributed systems, distributed real-time systems, fault tolerant systems, parallel computer architecture, parallel programming as well as traditional system-on-chip issues will appear relevant but within the constraints of a single chip VLSI implementation.
