WiMAX Security and Quality of Service

This book explains why applications running on cloud might not deliver the same service reliability, availability, latency and overall quality to end users as they do when the applications are running on traditional (non-virtualized, non-cloud) configurations, and explains what can be done to mitigate that risk.

QoS (Quality of Service) and Network Management are old topics. However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in… It begins by examining the mechanisms that already existed in fixed IP data networks prior to the introduction of probe and agent technology. A look at these later developments is then supplemented with a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis. This same model is then applied to a wireless environment examining which elements are required to be able to deliver multimedia services across 2nd and 3rd generation mobile networks, detailing the components of data networking that will assist in guaranteeing service level performance and the constraints placed on those guarantees when passing services over an air interface to a wireless-enabled device. It asks a simple question: will multimedia applications and the guaranteed levels of service required by them work when traversing from fixed to wireless networks? It tracks QoS components and mechanisms of both environments and looks at what will provide the glue in this brave new converged world and also provides empirical data to back up the conclusions drawn. * First book available which applies QoS techniques and technologies to wireless/mobile networks 3G/UMTS * Deals with the search for the real time information that constitutes the «customer experience» in terms of application performance so that service levels can be verified against measurable and relevant data in a true end-to-end manner across both fixed and wireless networks * Presents probe and agent technology * Features a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis – this will be of particular interest to practitioner * Analyses which elements are required in order to deliver multimedia services across 2nd and 3rd generation mobile networks * Details the components of data networking that will assist in guaranteeing service level performance Essential reading for Wireless and IP data network professionals/practitioners, network managers and architects, technical consultants, quality assessment engineers, infrastructure vendors, application developers, portal designers, wireline operators, lecturers, postgraduates, senior undergraduate students and industry trainees.

We present queueing-based algorithms to calculate the bandwidth required for a video stream so that the three main Quality of Service constraints, i.e., end-to-end delay, jitter and packet loss, are ensured. Conversational and streaming video-based applications are becoming a major part of the everyday Internet usage. The quality of these applications (QoS), as experienced by the user, depends on three main metrics of the underlying network, namely, end-to-end delay, jitter and packet loss. These metrics are, in turn, directly related to the capacity of the links that the video traffic traverses from its source to destination. The main problem that this book addresses is how much bandwidth we should allocate on the path from source to destination of a video traffic flow such that the end-to-end delay, jitter and packet loss of the video packets are within some expected required bounds.

While more and more data is shifted from circuit-switched to packet-switched networks, the users of these networks expect a smooth, continuously unproblematic service (unrelated to the amount of data transported). Therefore, the reliability of a network as well as the satisfaction of its users relies largely on Quality of Service (QoS). Service quality through resource management in IP networks will ensure that sufficient resources are available to fulfil the delay of applications and packet loss requirements. This year several books on QoS from the angle of operators/engineers have been published HOWEVER, none of these titles tackle the management side of the problem. This book shows how to determine quality requirements of services, it discusses and considers the various means of allocating network resources and of supervising the service quality. Furthermore, it explores strategies for allocating network resources and their relation to revenue or operator utility as well as service allocation optimization. The book concludes with a Nokia case study that illustrates the previously mentioned concepts. Essential reading for networking professionals wishing to understand service quality management in IP networks, as well as students needing to understand principles and basic techniques of service quality management.
