Perform nce Modeling of Multi-Layered OS1 communication Architectures
Adrian E. Conway · 1989
A generic queueing network model is formulated for the analytical performance evaluation of communication networks which are layered according to the OS1 Reference Model. The proposed model, based directly on the generic specifications of the Reference Model, may be used to quantitatively evaluate end-to-end mean performance measures taking into account multiple layers of protocol, a multitude of open connections across the network, the underlying topology, and the manner in which the processing capacity is distributed among the various entities. For the solution of the model, a computationally efficient iterative decomposition algorithm is formulated. To justify the methodology formulated here, we review previous work in the area of the analysis of layered systems and expose the limitations of hitherto proposed performance evaluation methodologies.
