Voice-Enabling the Data Network: H.323, MGCP, SIP, QoS, SLAs, and Security

Understand Voice over IP components and design practices for new or migrated VoIP networks Voice-Enabling the Data Network helps you understand: - Migration steps away from a pure circuit-switched TDM architecture to an IP-based network to support VoIP services- How to design and implement a large-scale VoIP network- QoS architectures and mechanisms to consider when provisioning bandwidth in a VoIP network- Common signaling types used to interconnect a VoIP gateway to a PSTN switch- Security measures that need to be implemented in a VoIP network: H.323 RAS Authentication, Network Access Security, and Device Security- Considerations when implementing a network management system to meet the customer's expectations of quality and reliability of the VoIP service-the Service Level Agreement- How H.323 VoIP networks, MGCP networks, and SIP networks coexist- Key components of VoIP solutions to help make appropriate business decisions when initiating a VoIP network project Voice over IP (VoIP) is a fast-growing technology within telecommunications companies, Internet service providers, and other companies seeking to migrate from traditional circuit-switched TDM networks. To enable successful migration to and design of VoIP networks, Voice-Enabling the Data Network provides a comprehensive overview of the various building blocks of VoIP networks. Voice-Enabling the Data Network describes the key steps in designing an operational VoIP network, thereby enabling network designers, managers, engineers, and CTOs to understand how the technology is applied. This book covers such essential topics as H.323, SIP, and MGCP architectures; QoS design considerations; Service Level Agreements (SLAs); and security considerations. With an emphasis on service providers, Voice-Enabling the Data Network covers how to provide a scalable and highly available VoIP network. You learn from timely discussions on unique VoIP topics and emerging technologies as you gain fundamental knowledge and understanding of all the important VoIP components and services that should be considered in the design of a VoIP network. James F. Durkin has 13 years of experience in the industry with voice and data technologies. Jim has real-world experience in designing and deploying VoIP solutions on a worldwide basis. He has led teams in deploying one of the first international-based wholesale VoIP networks in Japan, Germany, and the Czech Republic. He was a principal representative for the following standards organizations: ANSI T1S1, the Network Management Forum, and the ATM Forum. Currently, Jim works as a systems engineer for Cisco Systems(r) focused on selling and supporting optical network solutions. Jim has bachelor's and master's degrees in electrical engineering from the Georgia Institute of Technology.Jim Durkin is the author of 'Voice-Enabling the Data Network: H.323, MGCP, SIP, QoS, SLAs, and Security', published 2002 under ISBN 9781587050145 and ISBN 1587050145.
