Abstract: The concept of dynamic queueing networks is introduced. Queueing networks are used for modeling the performance aspects of a computer system with a dynamic structure, and a Generalized Stochastic Petri Net (GSPN) is used for modeling the fault tolerance aspects of the system. The GSPN is used to construct a Markovian model that describes the dynamic structure. The GSPN model world is extended with so called covered transitions which are useful for describing certain phenomena in fault tolerant computer systems. The modeling technique allows assessment of aspects such as recovery, routing and reconfiguration.
Keywords: performance queueing network; generalized stochastic net; covered transition; recovery; reconfiguration.
