Download or read book QoS Over Heterogeneous Networks written by Mario Marchese and published by John Wiley & Sons. This book was released on 2007-04-30 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of quality of service (QoS) has risen with the recent evolution of telecommunication networks, which are characterised by a great heterogeneity. While many applications require a specific level of assurance from the network; communication networks are characterized by different service providers, transmission means and implementer solutions such as asynchronous transfer mode (ATM), Internet protocol version 4 (IPv4), IPv6 and MPLS. Providing comprehensive coverage of QoS issues within heterogeneous network environments, “QoS Over Heterogeneous Networks” looks to find solutions to questions such as does QoS fit within heterogeneous networks and what is the impact on performance if information traverses different network portions that implement specific QoS schemes. Includes: A series of algorithms and protocols to help solve potential QoS problems. State of the art case studies and operative examples to illustrate points made. Information on QoS mapping in terms of service-level specification (SLS) and an in-depth discussion of related issues Chapters end-to-end (E2E) QoS, QoS architecture, QoS over heterogeneous networks and QoS internetworking and mapping. An ideal book for graduate students, researchers and lecturers. System designers, developers and engineers will also find “QoS Over Heterogeneous Networks” a valuable reference.

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.

Download or read book A New Framework for H 264 Video Delivery Over Heterogeneous Networks written by Ujwal G. Shirwadkar and published by . This book was released on 2006 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diverse and changing nature of the service requirements among emerging Internet application calls for network architecture that is both flexible and able to distinguish among the needs of the application. In this thesis a new framework has been proposed which focuses on achieving an End-to-End Quality of Service for video traffic in a heterogeneous network. The core components of the framework are state-of-art H.264 codec, Differentiated network model and IEEE 802.lle protocol. H.264 standard was chosen due to its intrinsic ability to adapt to network delays and its average reduction in bit rate by up to 50% for similar encoders. DiffServ architecture provides mechanism for aggregate traffic and prioritized individual flow, that together can be used to build service with varying delay and loss behavior. The newly introduced IEEE 802.11e being the only protocol to support QoS in wireless was chosen to provide the mobile receivers with higher quality of delivered video. To construct this framework modification to functioning of ingress router is proposed since IP packets were assigned drop probabilities by ETBMS. The source marker marked the packets containing video slices (I,-P, B) and also assigned priorities to the packets. The framework also describes a Video Differentiator present in the access point which identifies and maps the video packets to corresponding IEEE 802.1 le prioritized video service queues. Using simulation, the proposed framework is verified by examining QoS parameters like peak signal to noise ratio, mean square error, end-to-end delay and Video quality metric (VQM). The results obtained from various simulations thus illustrate that the framework achieves its goal of guarantying endlto end QoS in a heterogeneous network.

Download or read book Heterogeneous Wireless Access Networks written by Ekram Hossain and published by Springer Science & Business Media. This book was released on 2008-09-18 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous wireless networking, which is sometimes referred to as the fourth-generation (4G) wireless, is a new frontier in the future wireless communications technology and there has been a growing interest on this topic among researchers and engineers in both academia and industry. This book will include a set of research and survey articles featuring the recent advances in theory and applications of heterogeneous wireless networking technology for the next generation (e.g., fourth generation) wireless communications systems. With the rapid growth in the number of wireless applications, services and devices, using a single wireless technology such as a second generation (2G) and third generation (3G) wireless system would not be efficient to deliver high speed data rate and quality-of-service (QoS) support to mobile users in a seamless way. Fourth generation (4G) wireless systems are devised with the vision of heterogeneity in which a mobile user/device will be able to connect to multiple wireless networks (e.g., WLAN, cellular, WMAN) simultaneously. This book intends to provide a unified view on the state-of-the-art of protocols and architectures for heterogeneous wireless networking. The contributed articles will cover both the theoretical concepts and system-level implementation issues related to design, analysis, and optimization of architectures and protocols for heterogeneous wireless access networks.

Download or read book Increasing Quality of Service Using Transport Layer Coding Over Parallel Heterogeneous Networks written by Jason Michael Cloud and published by . This book was released on 2016 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: A shift in the way the Internet is accessed and the type of traffic generated has been underway for the last decade and will continue into the foreseeable future. Furthermore, these shifts are expected to place considerable strain on the ability of existing transport layer protocols to meet users' quality of service demands. Internet traffic is being generated by an increasing number of inexpensive, low-power, mobile devices resulting in an increased incidence of packet losses, unreliable network connections, and path instability. In addition, the majority of traffic, such as streaming video, is fast becoming more delay sensitive driving changes throughout the network. This thesis explores methods to improve end-to-end performance through the use of network and erasure coding techniques applied at the transport layer. These techniques will help provide path diversity and connection resiliency in the form of multi-path transport, in addition to increasing throughput and decreasing in-order delivery delay in the presence of network disruptions and packet erasures. The potential gains of a network coded transport layer are first introduced using two protocols: Coded TCP (CTCP) and Multi-Path TCP with Network Coding (MPTCP/NC). These two approaches help illustrate different methods to implement network coding to help overcome packet losses and diversify network connections over multiple paths. Analytic and experimental results are provided that show a network coded transport layer can significantly improve throughput in challenged networks; but more importantly, these results hint at the possible gains for application layer quality of service. Observing the performance of HTTP requests and streaming video, the potential to decrease the in-order delivery delay is highlighted. Based off of the observations outlined above, the second half of the thesis explores different code constructions that reduce in-order delivery delay in multiple path networks. A generation-based systematic code construction, similar to the one used in CTCP, is modeled and analyzed. Of particular note is the inherent trade-off between increasing the generation size to reduce the probability of decode errors resulting in retransmissions and keeping the generation size small enough so that coding delay is minimized. Furthermore, the trade-off between delay and efficiency is explored to help quantify the cost of reducing delay so that a user's quality of service constraint is met. Finally, a multiple path streaming code construction that removes the artificial constraints imposed by partitioning packets into generations is explored. Comparisons between the two constructions help highlight the importance of feedback in reducing delay, as well as the advantages and disadvantages of one type of code construction over the other.

Download or read book Theory and Engineering of Complex Systems and Dependability written by Wojciech Zamojski and published by Springer. This book was released on 2015-06-14 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building upon a long tradition of scientifi c conferences dealing with problems of reliability in technical systems, in 2006 Department of Computer Engineering at Wrocław University of Technology established DepCoS-RELCOMEX series of events in order to promote a comprehensive approach to evaluation of system performability which is now commonly called dependability. Contemporary complex systems integrate variety of technical, information, soft ware and human (users, administrators and management) resources. Their complexity comes not only from involved technical and organizational structures but mainly from complexity of information processes that must be implemented in specific operational environment (data processing, monitoring, management, etc.). In such a case traditional methods of reliability evaluation focused mainly on technical levels are insufficient and more innovative, multidisciplinary methods of dependability analysis must be applied. Selection of submissions for these proceedings exemplify diversity of topics that must be included in such analyses: tools, methodologies and standards for modelling, design and simulation of the systems, security and confidentiality in information processing, specific issues of heterogeneous, today often wireless, computer networks, or management of transportation networks. In addition, this edition of the conference hosted the 5th CrISS-DESSERT Workshop devoted to the problems of security and safety in critical information systems.
