In this book, Dan Minoli clearly explains IPv6 and how telephone networks can be built on the foundation. This is not just another book of IPv6, but it focuses on those aspects relevant to the IPv6 internet telephony systems and voice networks. Minoli uses to compare / contrast approach, exploring where IPv6 is similar to IPv4 and where it differs, to let you quickly understand the essence of IPv6 and the similarities (and differences) between current IPv4-based systems and IPv6-based systems. If you will be designing, implementing, or maintaining the next generation of internet phone system, then you need the information in this book! * Explain the essential concepts of IPv6 and how they relate to Internet telephony * Describes how Internet telephony systems using IPv6 are different, and better than, Internet telephony systems based on the older IPv4 standard * Discusses how to transition existing IPv4 Internet telephone systems and conventional switched systems to IPv6-based systems * Extensive treatment of security issues, including the IP layer encryption and authentication methods * Explain the connection techniques, including "plug and play" approach, for equipment used in IPv6 systems * The first title describes how the next-generation Internet protocol, IPv6 can be used for internet telephony * Explains IPv6 that applies to Internet telephony (VoIP) * Shows how IPv6 gives better security, QoS, and signal integrity in Internet telephony
