| Numerous attempts have been made in the past to integrate voice and data onto one network. The differing characteristics of voice and data have placed conflicting demands on the individual networks - voice uses a circuit-switched network, while data uses a packet-switched network. This timely book explores the promise of a converged network, which permits voice, video, and data to be carried in the same packet-switched network using the same packet format. As converged networks are reaching maturity and are being deployed by major telecom providers, the author offers you insightful discussions on the rewards that convergence allows, such as significant cost reductions, more efficient utilization of resources, the development of Web-based call centers, and unified messaging.
This extensive book:
- Reviews why VoIP has become the most prominent technology for network convergence;
- Covers new technologies like MPLS, Session Initiation Protocol, and Megaco/H.248 protocol, which have improved reliability and quality-of-service capability in converged networks;
- Gives a complete picture of converged network architectures, including Voice over IP, Voice over ATM, and Voice over frame relay;
- Covers basic concepts like SONET, advanced intelligent networks, and voice-coding algorithms and standards, which are fundamental to understanding the converged network;
- Fills the gaps in the current convergence literature, outfitting network planners and engineers, telecom system designers and implementers, and telephony carriers and developers with an invaluable resource. | |
