| NOTAS: | "Analysts agree that within the next decade virtually all telecommunications traffic will travel over packet networks. Should your packetized voice be delivered over Layer 2 networks such as ATM or Frame Relay, or over Layer 3 IP networks? Drawing upon years of practical experience with voice over data implementations, the authors of this book consider the advantages and disadvantages of IP versus traditional packet networks. The book explores the unique engineering problems posed by running voice over a connectionless network. And it supplies guidelines to help you decide when (or whether) to invest, and how to choose the best technologies for your organization." |
