One of the hottest topics in the telecommuncations industry today is the migration of voice traffic from the circuit switched Telco networks to packet switched networks such as IP, ATM, Frame Relay and access technologies such as DSL (Digital Subscriber Line) and Packet Cable. The sheer volume of voice traffic, together with the efficiencies of packet transport and the opportunity to offer new features on voice calls, has made internetworking, between circuit and packet transport, vital while this migration is in progress. Presents a concise treatment of a complex subject providing up-to-date coverage of all relevant packet voice technologies and an evaluation of how they compare Explains how and why to transport voice over packet networks Includes MEGACO: Media Gateway Control Protocol, Voice over Packet Cable and Voice over DSL Enables the reader to obtain information rapidly by featuring numerous bulleted lists and extensive diagrams Voice over Packet Networks is comprehensive and compact and will be welcomed by both engineers and planners in the telecommunications industry, as well as graduate and senior undergraduate students on telecommunication courses.

Understand how new network technologies impact VoIP! Voice over Internet Protocol (VoIP) is revolutionizing the way people communicate – both in the corporate world and in personal life. The enormous success of VoIP has led to its adoption in a wide range of networking technologies. Each network technology has its unique features and poses distinct challenges for the performance of VoIP. VoIP: Wireless, P2P and New Enterprise Voice over IPdescribes the issues arising in the deployment of VoIP in an emerging heterogeneous network environment. Along with a brief overview of the concepts, protocols, algorithms, and equipment involved in realizing VoIP, this book focuses on two areas: quality and performance issues in deploying VoIP over various network settings, and the new mechanisms and protocols in these emerging networks to assist the deployment of VoIP. VoIP: Wireless, P2P and New Enterprise Voice over IP: Discusses the basics of VoIP, VoIP codecs and VoIP Protocols including SIP and H.323. Details new technologies such as P2P technology, VoWiFi, WiMax, and 3G Networks. Explains the QoS issues arising from deploying VoIP using the new technologies. Solves the performance issues that arise when VoIP is deployed over different network technologies. This book is an invaluable resource for professional network engineers, designers, managers, researchers, decision makers and project managers overseeing VoIP implementations. Market analysts, consultants, and those studying advanced undergraduate and graduate courses on data, voice and multimedia communications will also find this book insightful.

For networking and RF/wireless engineers, and graduate students who want a solid overview of voice over WLANs/VoIP technology (wireless local area networks / voice over internet protocol), this book covers voice coding, packet loss, delay and 'jitter', and 'echo' control, and shows how to combine both WLAN and VoIP technology to create effective voice over WLAN systems. Finneran also describes how to integrate voice over WLAN systems with cellular networks. This is not just another WLAN-only book nor a VoIP-only book; instead, it integrates both topics into a coherent whole.* Gives complete details on integrating voice and data services on WLANs, including wide area networks* Explores quality of service (QoS) and security issues* Step-by-step descriptions of how to plan and implement voice over WLAN networks

This book addresses three important issues in VoIP networks: Quality of Service, pricing and security. In addressing Quality of Service (QoS), it introduces the notion of delay not exceeding an upper limit, termed the bounded delay, to measure the Quality of Service in VoIP networks. Queuing models are introduced to measure performance in terms of bounded delays. Closed form solutions relating the impact of bounding delays on throughput of VoIP traffic are provided. Traffic that exceeds the delay threshold is treated as lost throughput. The results addressed can be used in scaling resources in a VoIP network for different thresholds of acceptable delays. Both single and multiple switching points are addressed. The same notion and analysis are also applied on jitter, another important indicator of the VoIP QoS This book also develops a pricing model based on the Quality of Service provided in VoIP networks. It presents the impact of quality of VoIP service demanded by the customer on the transmission resources required by the network using an analytical approach. In addition, it extends and applies the delay throughput analysis developed for VoIP networks in assessing the impact of risks constituted by a number of transportation channels, where the risk associated with each channel can be quantified by a known distribution. Finally, the book explores areas for future research that can be built on the foundation of research presented.

Configuring Cisco Voice Over IP, Second Edition provides network administrators with a thorough understanding of Cisco's current voice solutions. This book is organized around the configuration of all of Cisco's core VoIP products, including Cisco CallManager software, Cisco 7910 series of phones, and server-based IP PBXs. In addition, AVVID coverage has been added.An update to a bestselling title in a growth market. Continued competitive pressure on ISPs to deliver VoIP will create strong demand information on topicVoice Over IP is expected to make great inroads in 2002. Voice-over-IP got its start at the time of the first edition of the book; it is now real and more companies are adopting it since IT managers have become less skeptical of IP telephony's reliability and more aware of the potential cost savings and application benefits of a converged network. Voip wares now promise easier quality-of-service (QoS) deployment, and a multitude of new IP phones and conferencing stations for corporations.Cisco and IBM recently announced a package deal that could help businesses quickly roll out IP voice in a small or midsize office. Since getting into the IP telephony market two years ago, Cisco has seen quick success in selling its voice-over-IP products into its vast installed base of IP LAN equipment customers. The firm was the top vendor of IP phones in the first quarter of this year and second in IP PBX system shipments (behind 3Com), according to Cahners In-Stat.

QoS is an important subject which occupies a central place in overall packet network technologies. A complex subject, its analysis involves such mathematical disciplines as probability, random variables, stochastic processes and queuing. These mathematical subjects are abstract, not easy to grasp for uninitiated persons. QoS in Packet Networks is written with two objectives. The first explains the fundamental mathematical concepts used in QoS analysis as plainly as possible, in layman's terms to afford the reader a better appreciation of the subject of QoS treated in this book. The second explains in plain language, the various parts of QoS in packet networks, to provide the reader with a complete view of this complex and dynamic area of communications networking technology. Discussion of the functional requirements of the packet networks to provide QoS is included.
