2007
Performance evaluation (Print)
Preserved Fulltext
First deriving the per-stream loss probability, delay, and delay variance of an isolated queue with multi-class input streams modeled by heterogeneous two-state Markovmodulated Poisson processes (MMPPs ...
In this paper, we investigate continuous-time tree-type queueing networks with Markovian external input models, i.e., MMPPs. ...
Without loss of generality, we may regard the original queue as a queue with only two input streams, one tagged stream with traffic load ρ t and the other aggregated cross stream with traffic load ρ c ...

Stochastic Automata Networks (SANs) are widely used in modeling practical systems such as queueing systems, communication systems, and manufacturing systems. ...
Usually, the steadystate distributions have no close form solutions and cannot be obtained efficiently by direct methods such as LU decomposition due to the huge size of the generator matrices. ...
The input of the queue comes from the superposition of several independent MMPPs, which is still an MMPP and is parameterized by two 2 n x 2 n matrices (Q, F). ...
