Once a guest on telephone lines, the Net now threatens a takeover of its host's principal function: voice-to-voice communications. For intrabusiness use or as a public system, Internet-based telephony can be a real money-saver - or money-maker. In Voice Over IP Networks, you'll learn everything you need to: transmit real-time voices over the Internet; understand the technology and its costs; compare leading vendors and their Internet telephony products - 3Com, Motorola, Lucent, VocalTec, Vienna Systems, Nuera Communications, and more; evaluate advantages of the IPv6 and IPv4 protocols; use RSVP, RTSP, IP Multicast, SONET, ATM, and other technologies for telephony; apply Codecs to voice digitization; emulate T1/E1 trunks; implement a system with appropriate standards; and anticipate trends and new products from innovative companies such as QWest.

IP (internet protocol) Telephony, enabled by softswitches, isgoing to usher in a new era in telecommunications. By putting voiceand data over one IP network, operators can enjoy lower costs andcreate new, revenue-generating "multimedia" services. This valuable reference offers a comprehensive overview of thetechnology behind IP telephony and offers essential information tonetwork engineers, designers and managers who need to understandthe protocols and explore the issues involved in migrating theexisting telephony infrastructure to an IP-based real timecommunication service. Drawing on extensive research and practical developmentexperience in VoIP from its earliest stages, the authors giveaccess to all the relevant standards and cutting-edge techniques ina single resource. IP Telephony: Deploying Voice-over-IP Protocols: Assumes a working knowledge of IP and networking and addressesthe technical aspects of real-time communication over IP. Presents a high level overview of packet media transporttechnologies, covering all the major VoIP protocols – SIP,H323 and MGCP Details specific strategies to design services for publicnetworks where endpoints cannot be trusted and can be behindfirewalls. Explores the problems that may arise from incomplete protocolimplementations, or architectures optimized for private networkswhich fail in a public environment. This amply illustrated, state-of-the art reference tool will bean invaluable resource for all those involved in the practicaldeployment of VoIP technology.

Seminar paper from the year 2005 in the subject Computer Science - Commercial Information Technology, grade: A (1,3), University of Auckland (Facultiy of Computing), course: Network and Protocols, language: English, abstract: Voice over IP (VoIP) is at the moment one of the most discussed topics in the current network scene. Besides the theoretical interest in network development, there is always the practical relevance which is of high importance for advances in network technology. One major proof, that VoIP research and its technology has a high impact on businesses is the fact that VoIP it is already implemented in a number of companies in the United States of America, UK, Ireland and South Korea, according to Cherry (2005). The following graphic shows the importance of VoIP for companies according to a recent international study conducted by Network Computing.

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.
