The properties of an IP network are significantly different from those of traditional telephony, audio, or video distribution networks. When designing applications that work over IP, you need to be aware of these unique characteristics, and make your system robust to their effects. The remainder of this book will describe an architecture for such systems, explaining RTP and its model for timing recovery and lip synchronization, error correction and concealment , congestion control, header compression, multiplexing and tunneling, and security. |
