Abstract. Highly interactive multimedia applications require variable
data rates during their presentation. Current admission control
mechanisms do not address the variable data rate requirements
appropriately for the following reasons: (1) classical admission control
mechanisms are based on the server-push approach, where the required
data rate has to be estimated in advance, and (2) worst-case resource
reservation is not economic. Client-pull models are more appropriate to
serve these kinds of applications. At the current state, there are no
suitable mechanisms that support admission control in client-pull
architectures at the server. In this paper, a session-oriented framework
for admission control is introduced that is based on two steps: (1) the
