Such geographical interdependencies clearly lead to relationship cycles: three ASs active primarily in the US, Europe, and Asia, but also present in the two other regions, may form a cycle by providing transit to each other for their primary renterestingly, this kind of information-losing abstractions of different-type objects or relationships as nodes or links of the same type explain cycles in other flow networks.
