NGN Architectures, Protocols and Services

Beschreibung

Comprehensive coverage explaining the correlation andsynergy between Next Generation Networks and the existingstandardized technologies This book focuses on Next Generation Networks (NGN); inparticular, on NGN architectures, protocols and services, includingtechnologies, regulation and business aspects. NGN providesconvergence between the traditional telecommunications and theInternet, and it is globally standardized by the ITU (InternationalTelecommunication Union), where ITU is the United Nationsspecialized agency for Information and Communication Technologies- ICTs. The convergence towards the NGN is based on theInternet technologies, and the introductory chapters cover theInternet fundamentals of today, including architectures, protocols(IPv4, IPv6, TCP, DNS, etc.), Internet services (WWW, e-mail,BitTorrent, Skype, and more), as well as Internet governance.Further, the prerequisite for convergence of all ICT services oversingle network architectures is broadband access to the Internet.Hence, the book includes architectures of fixed broadband Internetaccess networks, such as DSL (Digital Subscriber Line) networks,cable networks, FTTH (Fiber To The Home), next generation passiveand active optical networks, and metro Ethernet. It also coversnetwork architectures for next generation (4G) mobile and wirelessnetworks (LTE/LTE-Advanced, and Mobile WiMAX 2.0), then FixedMobile Convergence - FMC, next generation mobile services, as wellas business and regulatory aspects for next generation mobilenetworks and services. * Comprehensive coverage explaining the correlation and synergybetween Next Generation Networks and the existing standardizedtechnologies * Focuses on Next Generation Networks (NGN) as defined by theITU, including performance, service architectures and mechanisms,common IMS (IP Multimedia Subsystem), control and signallingprotocols used in NGN, security approaches, identity management,NGN Service Overlay Networks, and NGN business models * Examines the most important NGN services, including QoS-enabledVoIP, IPTV over NGN, web services in NGN, peer-to-peer services,Ubiquitous Sensor Network (USN) services, VPN services in NGN,Internet of things and web of things * Includes the transition towards NGN from the PSTN (PublicSwitched Telephone Networks) and from the best-effort Internet viathe same Internet access * Explores advanced topics such as IPv6-based NGN, networkvirtualization, and future packet based networks, as well asbusiness challenges and opportunities for the NGN evolved networksand services Essential reading for engineers and employees from regulatorybodies, government organisations, telecommunication companies, ICTcompanies.
