Methods and devices for characterizing the interconnection efficiency of a computer network based upon a static routing scheme are disclosed. The network comprises a plurality of items of equipment. After having determined (105) a plurality of types of links between said items of equipment, a theoretical number of routes per link and the associated number of links are determined (120, 125) for each type of at least one subset of said plurality of types of links according to the topology of said network. The determined theoretical number of routes per link and the associated number of links are then aggregated (135) to estimate at least one optimal routing point characterizing the theoretical efficiency of the network. Such optimal routing points can be compared with estimated actual routing points based upon the aggregation of actual numbers of routed per link and associated actual numbers of links to characterizes the network efficiency.
