Interactive Applications

The user-perceived performance of interactive applications is often determined by very different parameters than for "batch" applications such as bulk file transfer. Often, responsiveness is the most important criterion. There are often fairly well-defined boundaries of response/feedback time beyond which the illusion of synchronicity breaks apart.

Important interactive applications include:

• Telephony, including "VoIP" (Voice over IP)
• Videoconferencing
• Multiplayer games and other collaborative environments.

Tips and Tricks

During discussions about how to get best performance for DVTS over an error prone, long distance connection, a Telia expert (Ola Holmstr�m) recommended avoiding the use of RTCP (and of course setting the TCP buffers to be sufficiently large,a s described in EndSystemTuning.
