Reader Reviews
Khasnabish writes for the communications engineer needing or wanting to learn about the increasingly popular VoIP. He explains in detail the differences between this and the traditional circuit switched approach of Public Switched Telephone Networks. We see a substantial contrast between the monolithically designed PSTN and the common choice of an open architecture for various VoIP implementations. Measuring the quality of a VoIP channel is also covered. Methods like buffering can be used to (partially) compensate for delay jitter. Unlike standard email or web usage of the Internet, the real time requirements of a voice interaction leads to significantly more complicated methods that sit atop TCP/IP. The book does not appear to mention IPv6. That has an explicit Quality of Service, to address such real time issues. Granted, v6 is still not heavily deployed. But it may simplify VoIP.
