Formal Performance Measures for Asymmetric Communication
Typically, any asymmetric network is characterized either by non-uniform link transmission bit rate or by uneven traffic intensity. Through monitoring and asymmetric network status control one can improve performance of the service-sector. In this paper, some exact analysis methods, oriented to achieve comparatively high utilization of the data packet transmission link and satisfy the service quality of the asymmetric loss and queueing systems, are proposed. The developed mathematical approach
... hematical approach turns out to be extremely useful for the analysis of the network node with asymmetric transmission links. Some comments concerning the application of a few different strategies to the selection of an unoccupied data packet transmission link are discussed. The straight process analysis in the asymmetric loss and queueing systems is carried out using continuous-time Markov chains. Performance of the asymmetric system is measured using accurate expressions. Finally, in the case of Poisson arrivals and exponential transmission times, an exact analytical model is applied to the system.
