Download or read book QOS Management with Adaptive Routing for Next Generation Internet written by Henry C. Quek and published by . This book was released on 2000-03-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up till today, the Internet only provides best-effort service, where traffic is processed as quickly as possible, with no guarantee as to timeliness or actual delivery. As the Internet develops into a global commercial infrastructure, demands for guaranteed and differentiated network quality of service (QoS) will increase rapidly. Several QoS service models have been developed to provide and support QOS in the Internet, namely: Integrated Service (IntServ), Differentiated Service (DiffServ) and MultiProtocol Label Switching (MPLS). QoS routing, such as Widest-Shortest Path, Shortest-Widest Path and Shortest-Distance Path, is required in order to support QoS and optimize the network resource utilization. The Server and Agent based Active network Management (SAAM) system is a network management system designed for the next generation Internet. It is capable of supporting all types of service. It will be able to control and optimize the utilization of the network through resource allocation and adaptive QOS routing. This thesis describes a design and implementation of the QoS Management component of a SAAM Server. This component optimizes the utilization of network resources and supports the various service classes in a cohesive manner. It utilizes an adaptive routing strategy to balance the network load.

This book was released on 2018-08-29 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently there are two approaches to provide Quality of Service (QoS) in the next generation Internet: An early one is the Integrated Services (IntServ) with the goal of allowing end-to-end QoS to be provided to applications; the other one is the Differentiated Services (DiffServ) architecture providing QoS in the backbone. In this context, a DiffServ network may be viewed as a network element in the total end-to-end path. The objective of this paper is to investigate the possibility of providing end-to-end QoS when IntServ runs over DiffServ backbone in the next generation Internet. Our results show that the QoS requirements of IntServ applications can be successfully achieved when IntServ traffic is mapped to the DiffServ domain in next generation Internet.Bai, Haowei and Atiquzzaman, Mohammed and Ivancic, WilliamGlenn Research CenterINTERNETS; QUALITY CONTROL; NETWORKS; PROTOCOL (COMPUTERS)...

Book Synopsis End-to-End Quality of Service by : Abdelhamid Mellouk
Download or read book End-to-End Quality of Service written by Abdelhamid Mellouk and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: A modern communication network can be described as a large, complex, distributed system composed by higher interoperating, smaller sub-systems. Today, the proliferation and convergence of different types of wired, wireless, and mobile networks are crucial for the success of the next generation networking. However, these networks can hardly meet the requirements of future integrated-service networks, and are expected to carry multimedia traffic with various Quality of Experience (QoE) and Quality of Service (QoS) requirements. Providing all relevant QoS/QoE issues in these heterogeneous networks is then an important challenge for telecommunication operators, manufacturers, and companies. The impressive emergence and the important demand of the rising generation of real-time Multi-service (such as Data, Voice VoD, Video-Conference, etc.) over communication heterogeneous networks, require scalability while considering a continuous QoS. This book presents and explains all the techniques in new generation networks which integrate efficient global control mechanisms in two directions: (1) maintain QoS requirements in order to maximize network resources utilization, and minimize operational costs on all the types of wired-wireless-mobile networks used to transport traffic, and (2) mix the QoS associated with home, access, and core networks in order to provide Quality of Service/Quality of Experience expected by users of new services.
Book Synopsis Virtualization-enabled Adaptive Routing for QoS-aware Software-Defined Networks by : Alba Xifra Porxas
Download or read book Virtualization-enabled Adaptive Routing for QoS-aware Software-Defined Networks written by Alba Xifra Porxas and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [ANGLÈS] Software-Defined Networking (SDN) has been recognized as the next-generation networking paradigm. It is a fast-evolving technology that decouples the network data plane, which are the network devices that forward traffic, from the network control plane, which is the software logic that controls ultimately how traffic is forwarded through the network. A logically centralized controller is responsible for all the control decisions and communication among the forwarding elements. It allows to control the network behavior from a single high level control program. However, Software-Defined Networks use many of its network resources inefficiently, which leads to over-loading network links, congestion in the queues and end-to-end packet delays. Consequently, it becomes clear that routing decisions affect the overall performance of a communication's network. Performance is determined in terms of Quality of Service guarantees, i.e. throughput, average packet delay, jitter and losses. Thus, a QoS-aware routing algorithm is required. Current traffic engineering techniques and state-of-the-art routing algorithms do not effectively use the merits of SDNs, such as global centralized visibility, real-time fast decisions, control and data plane decoupling, network management simplification and portability. In this thesis, we developed two new QoS-aware routing algorithms that exploit the advantages that SDN brings to improve the network performance. Two different scenarios have been studied: a centralized and a distributed models. The centralized scenario simplifies the management of complex flows and the customization, but scalability issues arise. In contrast, the distributed scenario is more scalable, but there may be state inconsistency and increase of shared information. In general, a centralized approach is better for data centers or home networks, whereas a distributed approach is better for large scale networks, e.g. cloud environments. First, the centralized SDN controller model is discussed, for which a multi-tenancy management framework is proposed to fulfill the quality-of-services (QoSs) requirements through tenant isolation, prioritization and flow allocation. A network virtualization algorithm is provided to isolate and prioritize tenants from different clients. Furthermore, a novel routing scheme, called QoS-aware Virtualization-enabled Routing (QVR), is presented. It combines the proposed virtualization technique and a QoS-aware framework to enable flow allocation with respect to different tenant applications. Simulation results confirm that the proposed QVR algorithm surpasses the conventional algorithms with less traffic congestion and packet delay. This facilitates reliable and efficient data transportation in generalized SDNs. Therefore, it yields to service performance improvement for numerous applications and enhancement of client isolation. Second, a distributed SDN controller model is analyzed. The network is divided into different clusters, and hierarchically split in two levels. This architecture leads to smaller sizes of routing tables in the switches, and substantially lesser calculations and updates of routing tables from the controller. Moreover, a new algorithm is developed, called QoS-aware Reinforcement Learning Routing (QRLR), where reinforcement learning is applied to the routing problem. The modeling of the reward function calculation solution allows the customization of the different requirements for each type of traffic, thus providing flexibility and adaptability to different flows and its requirements.
Book Synopsis QOS-Enabled Networks by : Miguel Barreiros

Available in PDF, EPUB and Kindle. Book excerpt: With a foreword by Kannan Kothandaraman "This is the first book about QOS that I actually enjoyed reading precisely because the authors focused on real-life QoS and not in academic discussions about it." Per Nihlen, IP Network Manager, NORDUnet The new authoritative, practical guide to delivering QOS guarantees This new benchmark in quality of service (QOS) study is written by two experts in the field who deal with QOS predicaments every day. The authors not only provide a lucid understanding of modern theory of QOS mechanisms in packet networks but how to apply them in practice. In addition, they detail the QOS management features found in modern routers used by Internet Service Providers (ISPs) and large enterprise companies and networks, all in an effort to enable network managers and engineers to configure production networks with a quality of service guarantee. The book's focus on addressing network behavior ("real effects") in relation to the configuration of network elements (routers and switches), is both refreshing and insightful. QOS-Enabled Networks contains up-to-date coverage of: QOS mechanisms in packet networks and how to apply them in practice QOS management features now common in modern-day routers How network behavior is related to configuration of network elements Layer 2 VPN and QOS QOS in mobile LTE networks QOS-Enabled Networks is an invaluable guide for networking engineers needing to provide QOS services for service providers, ISPs and large enterprises, as well as for network design and operations engineers.

Book Synopsis Quality of Experience for Multimedia by : Abdelhamid Mellouk
Download or read book Quality of Experience for Multimedia written by Abdelhamid Mellouk and published by John Wiley & Sons. This book was released on 2013-11-25 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a convergence of network technologies, the Next Generation Network (NGN) is being deployed to carry high quality video and voice data. In fact, the convergence of network technologies has been driven by the converging needs of end-users. The perceived end-to-end quality is one of the main goals required by users that must be guaranteed by the network operators and the Internet Service Providers, through manufacturer equipment. This is referred to as the notion of Quality of Experience (QoE) and is becoming commonly used to represent user perception. The QoE is not a technical metric, but rather a concept consisting of all elements of a user's perception of the network services. The authors of this book focus on the idea of how to integrate the QoE into a control-command chain in order to construct an adaptive network system. More precisely, in the context of Content-Oriented Networks used to redesign the current Internet architecture to accommodate content-oriented applications and services, they aim to describe an end-to-end QoE model applied to a Content Distribution Network architecture.

Book excerpt: th We are delighted to present the proceedings of the 11 Asia-Paci?c Network Operations and Management Symposium (APNOMS 2008) which was held in Beijing, China, during October 22–24, 2008. TheOrganizingCommittee(OC)selectedthethemeofthisyear’ssymposium as “Challenges for Next-Generation Network Operations and Service Mana- ment. ” Research and development on next-generation networks (NGNs) have been carried out over the last few years and we are already seeing their - ployment and operations in many parts of Asia-Paci?c countries. We are also beginning to experience new and interesting services that utilize these NGNs. We are certain that we will see more deployment of NGNs and NGN services in the next few years. Thus, the operations and management of NGNs and their services are very important to the network operators and service providers. At the same time, they are also concerned about new and more e?ective ways of performing the operations and management. This year, the APNOMS call for papers received 195 paper submissions from 19di?erentcountries,includingcountriesoutsidetheAsia-Paci?cregion(Europe, Middle-East, North and South America). Each paper was carefully reviewed by at least three international experts. Based on review scores, the APNOMS 2008 Technical ProgramCommittee discussed the selection of papers, and selected 43 high-quality papers (22. 1% of submissions) as full papers and 34 papers as short papers. Accepted papers were arrangedinto ten technical sessions and two short paper sessions (poster presentation).
Book Synopsis Quality of Service by : Paul Ferguson
Download or read book Quality of Service written by Paul Ferguson and published by . This book was released on 1998-02-09 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
