Sammendrag

One type of Internet services that have recently gained much attention are services that enable people around the world to communicate in real-time. Such services of real-time interaction are offered by applications most commonly referred to as distributed interactive applications. A time-dependent requirement generally applies to all distributed interactive applications that aim to support real-time interaction, and is usually in terms of a few hundred milliseconds.

One general focal point in Vik's thesis is to enable scalable group communication for managing dynamic groups of clients that interact in real-time. The desire is to enable people around the world to dynamically join networks of participants and interact with them in real-time.

The main contributions of the thesis are a number of investigations of a wide variety of group communication techniques. The results from the investigations form a foundation to identify the techniques that are particularly suitable for distributed interactive applications.
