Covers the latest standards and those being developed in an ever-evolving field Provides insight into the latest technology of video and data over wireless networks and how convergence will be a driving force in this industry Provides an understanding of the true capabilities behind each vendor's solution to allow for informed buying decisions A recent survey of 500 U.S. companies with multiple locations found that 81% are planning to implement IP Telephony on their local area networks (LANs) in 2003, and two-thirds are looking at convergence for their wide area networks (WANs) as well. This includes voice, video and data over hard line and wireless networks. Today, new standards and technologies are being developed to support convergence and voice over IP (VoIP) and Video over IP and wireless. Because convergence covers the voice and data world, it will be critical to understand all of these environments. Voice, Video, and Data Network Convergence provides detailed information on convergence network models, protocol stacks, routing algorithms, gateways and switches required to support these networks. Covers the latest standards and those being developed in an ever-evolving field Provides insight into the latest technology of video and data over wireless networks and how convergence will be a driving force in this industry Provides an understanding of the true capabilities behind each vendor's solution to allow for informed buying decisions
