Distributed Object-Oriented Simulation of Heterogeneous Communication Systems

A common scenario in media processing is that a media server is used to save and retrieve the data. For the pro- cessing, a data stream is sent to other (computing) servers which, once it is processed, can send it back to the me- dia server or to the requesting client. In this case, the computing power of the media server is saved at the price of increased communication bandwidth. Simulation is in- evitable for the effective development of such systems. Simulations and emulation techniques can be used to esti- mate the key parameters like required bandwidth, maximal amount of clients etc. at very early stages of the develop- ment (1). Such estimates are especially important to ensure the quality of service, determine possible bottlenecks etc. This work presents a innovative concept for the coupling of different simulation tools which enables such simulations.
