And this book is your guide to that future.IPv6 is the replacement for the currently used IPv4 (Internet Protocol version 4). IPv6 will offer increased IP addresses (full 128-bit addresses, compared to the 32-bit addresses of IPv4), enhanced security, and greater robustness. It will also be fully "backwards compatible? with existing IPv4 systems. These capabilities will finally make Internet telephony a viable competitor to conventional switched telephone networks. In this book, Dan Minoli clearly explains IPv6 andCommunications engineering series.Architectures for next generation VoIP networksInternet telephonyInternet telephony.621.382/12Minoli Daniel1952-535872MiAaPQMiAaPQMiAaPQBOOK9910784349903321Voice over IPv61212795UNINA
