Future Internet Services and Service Architectures presents state-of-the-art results in services and service architectures based on designs for the future Internet and related emerging networks. The discussions include technology issues, key services, business models, and security. The work describes important trends and directions. Future Internet Services and Service Architectures is intended to provide readers with a comprehensive reference for the most current developments in the field. It offers broad coverage of important topics with twenty chapters covering both technology and applications written by international experts. The 20 chapters of Future Internet Services and Service Architectures are organized into the following five sections:-• Future Internet Services -- This section contains four chapters which present recent proposals for a new architecture for the Internet, with service delivery in the Future Internet as the key focus.• Peer-to-Peer Services -- Using the P2P network overlay as a service platform, five chapters explore the P2P architecture and its use for streaming services, communication services, and service discovery.• Virtualization -- Virtualization and its benefits for resource management, supporting hetereogeneity, and isolation are the basis for five chapters which describe virtualization at the endpoint, in the cloud, and in the network.• Event-Distribution -- Publish/Subscribe mechanisms are important for applications which require time-sensitive delivery of notifications. The two chapters in this section present recent developments in publish/subscribe load balancing and in sensor networks.• VANETs - Vehicular Ad Hoc Networks (VANETs) are a network technology which are designed for vehicle-to-vehicle and vehicle-to-infrastructure connectivity for moving vehicles. The four chapters in this section provide an introduction to VANETs, routing, services and system architecture.Future Internet Services and Service Architectures is complemented by a separate volume, Advances in Next Generation Services and Service Architectures, which covers emerging services and service architectures, IPTV, context awareness, and security.
The merging of voice and data on a single network opens powerful new possibilities in communications. Only a fundamental understanding of both technologies will ensure you are equipped to maximise their full potential. Convergence Technologies for 3G Networks describes the evolution from cellular to a converged network that integrates traditional telecommunications and the technology of the Internet. In particular, the authors address the application of both IP and ATM technologies to a cellular environment, including IP telephony protocols, the use of ATM/AAL2 and the new AAL2 signalling protocol for voice/multimedia and data transport as well as the future of the UMTS network in UMTS Release 5/6 All-IP architecture. Convergence Technologies for 3G Networks: Explains the operation and integration of GSM, GPRS, EDGE, UMTS, CDMA2000, IP, and ATM. Provides practical examples of 3G connection scenarios. Describes signalling flows and protocol stacks. Covers IP and ATM as used in a 3G context. Addresses issues of QoS and real-time application support. Includes IP/SS7 internetworking and IP softswitching. Outlines the architecture of the IP Multimedia Subsystem (IMS) for UMTS. Convergence Technologies for 3G Networks is suited for professionals from the telecommunications, data communications and computer networking industries..
This book is for programmers who want to learn about real-time communication and utilize the full potential of WebRTC. It is assumed that you have working knowledge of setting up a basic telecom infrastructure as well as basic programming and scripting knowledge.
Extensively updated evaluation of current and future network technologies, applications and devices This book follows on from its successful predecessor with an introduction to next generation network technologies, mobile devices, voice and multimedia services and the mobile web 2.0. Giving a sound technical introduction to 3GPP wireless systems, this book explains the decisions taken during standardization of the most popular wireless network standards today, LTE, LTE-Advanced and HSPA+. It discusses how these elements strongly influence each other and how network capabilities, available bandwidth, mobile device capabilities and new application concepts will shape the way we communicate in the future. This Second Edition presents a comprehensive and broad-reaching examination of a fast-moving technology which will be a welcome update for researchers and professionals alike. Key features: Fully updated and expanded to include new sections including VoLTE, the evolution to 4G, mobile Internet access, LTE-Advanced, Wi-Fi security and backhaul for wireless networks Describes the successful commercialization of Web 2.0 services such as Facebook, and the emergence of app stores, tablets and smartphones Examines the evolution of mobile devices and operating systems, including ARM and x86 architecture and their application to voice-optimized and multimedia devices

Providing an holistic approach to IMS technologies, IMS: A Development and Deployment Perspective explores service architecture for development and delivery of IMS services. Approaching IMS from the perspective of the user and the service provider it examines both the current state of deployment and future trends. The book offers a realistic view of IMS deployment to operators and service providers, giving practical examples, application cases and business models. It also presents IMS deployment strategies based on real-life deployment statistics from a live IMS test bed connected to an operator network and proof-of-concept applications including inter-operability trials and results. Focusing on IMS potential in terms of service creation, service composition and service provision the book discusses the ability of IMS to act not only as a service delivery framework, but also as a service integration framework. It presents the possible future of IMS in terms of convergence with Internet services, including discussions about integration with web technologies including the WIMS 2.0 initiative. The book enables a better understanding of how web technologies can complement the IMS service architecture and pioneer the post-IMS progress and success. Presents a novel service-oriented approach to IMS services and applications from a deployment perspective Places IMS in the context of the current telecom environment providing business models through WIMS 2.0 initiative Predicts the trends and potential future for the IMS evolution Provides a technical foundation to IMS principles and architecture Gives examples and solutions to the challenges of service creation and implementation and analyses deployment hurdles and interoperability trials Describes trends of convergence based on IMS and Web technologies
