Adaptive QoS in Multimedia Systems [chapter]

M. Ott, G. Michelitsch, D. Reininger, G. Welling
1997 Building QoS into Distributed Systems  
Each layer in a software system deals with QoS at its appropriate level of abstraction using a generic API for communicating QoS parameters and values to layers above and below.  ...  To verify these ideas we built a proof-of-concept multimedia system (Ott, 1997) which showed that our architecture is not only feasible but offers a powerful framework for building adaptive multimedia  ...  CONCLUSION Based on our strong belief that future multimedia systems will be both distributed and heterogeneous, and the experience gained from building several multimedia prototypes in the past, we advocate  ...
