The authors consider an emerging class of challenging Internet applications called Real-time Online Interactive Applications (ROIA). Examples of ROIA are multiplayer online games, computation and interaction-intensive training, simulation based e-learning, etc. These applications make high QoS demands on the underlying network which involve the number of users and the actual application state and, therefore, vary at runtime. In traditional networks, the reconfiguration possibilities of the network to meet the dynamic QoS demands of ROIA are limited due to the lack of control of the network.
