 Author(s) : Peter Massam Publisher : Wiley Year : Sep 2002 ISBN 10 : 0470848480 ISBN 13 : 9780470848487 Language : English Pages : 180 File type : PDF Size : 11.4 MB 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.  Author(s) : Annlee A. Hines Publisher : Wiley Year : Aug 2002 ISBN 10 : 047123284X ISBN 13 : 9780471232841 Language : English Pages : 336 File type : PDF Size : 5.9 MB Keep your network safe from security disasters with a dependable recovery strategy. Companies are finally learning that a network disaster recovery plan is mandatory in these times, and they must be prepared to make difficult choices about network security. In the information-packed pages of this book, Annlee Hines shares her unique and diverse work experience. She explains that the first thing you need, whatever your business may be, is reliable information and an idea of what you need to protect, as well as what you are protecting it from. She then dives into a discussion of how much you can expect to spend depending on what kind of security your network requires. She also delves into addressing the variables that determine why your needs will not necessarily be the needs of your closest competitor. Most importantly, Hines writes this valuable material realizing that you already know how to do your job --it's just that you now have to reconsider just how vulnerable the information nervous system of your company really is.  Author(s) : Howard Berkowitz Publisher : Wiley Year : Jul 2002 ISBN 10 : 0471099228 ISBN 13 : 9780471099222 Language : English Pages : 592 File type : PDF Size : 2.4 MB To be competitive, service providers cannot customize every installation but must simultaneously offer services that meet a wide range of perceived customer needs. This guide shows commercial service providers and equipment vendors how to build competitive service offerings for enterprise-specific needs. In general, the book is organized into three main parts. Chapters 1 through 5 deal with defining customer requirements and the abstract provider architecture. Chapters 6 through 8 deal with building and extending carrier facilities and transmission systems. Chapters 9 through 13 deal with the intelligent communications systems overlaid onto the physical structures, which to varying extents involve Internet Protocol (IP)–based control planes, and possibly IP forwarding. This book focuses on the service provider network, and ideally will be read in concern with the more customer-oriented WAN Survival Guide. It is not aimed at protocol implementers, although it does present alternatives between techniques in development. If a reader finishes the book and is disappointed that he or she did not become utterly familiar with bit-level techniques, I have succeeded in my goals! There are many excellent sources for dealing with protocol mechanics, but a shortage of sources for pinning down problems and selecting solutions. WiMAX: Technology for Broadband Wireless Access | 13 MB WiMAX Broadband Wireless Access Technology, based on the IEEE 802.16 standard, is at the origin of great promises for many different markets covering fixed wireless Internet Access, Backhauling and Mobile cellular networks. WiMAX technology is designed for the transmission of multimedia services (voice, Internet, email, games and others) at high data rates (of the order of Mb/s per user). It is a very powerful but sometimes complicated technique. The WiMAX System is described in thousands of pages of IEEE 802.16 standard and amendments documents and WiMAX Forum documents. WiMAX: Technology for Broadband Wireless Access provides a global picture of WiMAX and a large number of details that makes access to WiMAX documents much easier. All the aspects of WIMAX are covered.  Author(s) : Grenville Armitage, Mark Claypool, Philip Branch Publisher : Wiley Year : Apr 2006 ISBN 10 : 0470018577 ISBN 13 : 9780470018576 Language : English Pages : 232 File type : PDF Size : 3.5 MB Today, computer games are sold to an increasingly significant market whose annual revenues already exceed that of the Hollywood movie industry. Multi-player games are making greater use of the Internet and the driving demand for ‘better than dial-up’ access services in the consumer space. Yet many networking engineers are unfamiliar with the games that utilise their networks, as game designers are often unsure of how the Internet really behaves. Regardless of whether you are a network engineer, technical expert, game developer, or student with interests across these fields, this book will be a valuable addition to your library. We bring together knowledge and insights into the ways multi-party/multi-player games utilise the Internet and influence traffic patterns on the Internet. Multi-player games impose loads on Internet Service Providers (ISPs) quite unlike the loads generated by email, web surfing or streaming content. People’s demand for realistic interactivity creates somewhat unique demands at the network level for highly reliable and timely exchange of data across the Internet – something the Internet rarely offers because of its origins as a ‘best effort’ service. Game designers have developed fascinating techniques to maintain a game’s illusion of shared experiences even when the underlying network is losing data and generally misbehaving.
