Abstract
The observed variations in network characteristics demand explanation. In this discussion it is possible to identify two types of explanation and two levels of aggregation. The two types of explanation can be characterised as idiographic (or historical) and nomothetic (or law-making). The two levels of aggregation are the network element (an individual route or access point) and the network as a whole. Although the historical approach is most commonly applied to network elements and the nomothetic approach to whole networks, there is no necessary relation between the level of aggregation and the type of explanation advanced.
