We present a simple model for the global performance evaluation of a packet switching network. Through a detailed analytical treatment, a set of formulae is derived which allow a compact and reliable evaluation of the most significant statistical properties of the network, such as the arrival probabilities, the queue states distribution and the mean utilizations of the links. Starting from the knowledge of these quantities, the network can be characterized also taking into account the mutual interaction between different nodes. An example is given with reference to a mesh-connected structure.
