The appearance of VoIP technology has now made feasible the use of data network for data, as well as voice communication. In this book, the protocol conversion between two different networks, packet scheduling and routing schemes for gateway selection has been introduced and also verified with Asterisk server. The recent trend for convergence of different access network technologies, market deregulation and emergence of dual-mode end-user devices allow the same destination to be reached by alternative paths and interfaces.Providing a good QoS in heterogeneous networks for irregular traffic flows remains a significant challenge. One of the difficult tasks is that of gateway location, also known as gateway selection, path selection, gateway discovery, and gateway routing. The main objective of this book is to design and develop a PSTN-IP Telephony Gateway (PITG) model and to assist routing packets while ensuring minimal call blocking probability with respect to call arrival rate or load, to increase the overall performance of the system. Specifically, the primary focus is on the development, analysis and optimization of the PITG model and evaluation of a gateway selection algorithm.

Public Switched Telephone Network

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.The public switched telephone network (PSTN) is the network of the world''s public circuit-switched telephone networks, in much the same way that the Internet is the network of the world''s public IP-based packet-switched networks. Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital and includes mobile as well as fixed telephones. The PSTN is largely governed by technical standards created by the ITU-T, and uses E.163/E.164 addresses (more commonly known as telephone numbers) for addressing.

Mobility Management Techniques for Wireless Net...

Mobility Management &amp, Route Optimization issues for Wireless Networks are presented in detail. IP-based Networks, PSTN-based Networks and ATM-based Networks backbones have been considered for developing mobility management technique. In IP-based backbone network, a route optimization scheme is proposed to improve the performance of Mobile IP having some apparent drawbacks like triangular routing problem, home agent overloading etc. An encapsulation at one- level up in the hierarchy is performed to improve the handoff delay and the simulation is carried out on NS-2 simulator. In PSTN-based backbone networks, a protocol is proposed and an analytical modeling is carried out where the location registration can be finished prior to the arrival of a MT at the new network to support the inter-system roaming. For an ATM-based backbone network, a design and prototyping of a mobility support ATM network is proposed to improve the handoff time, cell loss and call setup time. Further, an improved mobile location management for wireless ATM networks is proposed and analyzed to improve the performance in terms of number of hops required for location managements.

Teletraffic Engineering
35,00 € *
ggf. zzgl. Versand

High Quality Content by WIKIPEDIA articles! Teletraffic engineering is the application of traffic engineering theory to telecommunications. Teletraffic engineers use their basic knowledge of statistics including Queueing theory, the nature of traffic, their practical models, their measurements and simulations to make predictions and to plan telecommunication networks at minimum total cost. These tools and basic knowledge help provide reliable service at lower cost. Because the approach is so different to different networks, the networks are handled separately here: the PSTN, broadband networks, mobile networks, and networks where the possibility of traffic being heavy is more frequent than anticipated.

High Quality Content by WIKIPEDIA articles! H.323 is an umbrella Recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences. It is widely implemented by voice and videoconferencing equipment manufacturers, is used within various Internet real-time applications such as GnuGK and NetMeeting and is widely deployed worldwide by service providers and enterprises for both voice and video services over Internet Protocol (IP) networks. It is a part of the ITU-T H.32x series of protocols, which also address multimedia communications over Integrated Services Digital Network (ISDN), Public Switched Telephone Network (PSTN) or Signaling System 7 (SS7), and 3G mobile networks. H.323 Call Signaling is based on the ITU-T Recommendation Q.931 protocol and is suited for transmitting calls across networks using a mixture of IP, PSTN, ISDN, and QSIG over ISDN.
