Analytical modelling of the network traffic performance
I. Garces, Daniel Franco, Emilio Luque · 2003
Interconnection network modeling is an important field in order to study and understand interconnection network behaviour and its significance in telecommunication applications and distributed systems. In this paper, we show an analytical model that represents interconnection networks. The model accepts as inputs the network load consisting of the network topology, routing, and the communication pattern of the application. Any topology of any size and different parameters for the router are supported. The model outputs the latency behaviour of the interconnection network for each channel on each link. The accuracy of the model is shown by comparison with network simulation. The model is useful to study the latency/load curve of communication patterns, to calculate average network delays to identify hot-spots in the network and to perform network analysis and design.
