In order to make practical use of this result, we present a methodology to model the communication system. The technique exploits the physical structure of existing networks, in particular its hierarchical nature, to create a communication graph where causal separators match the underlying physical and administrative organization. We show that this approach can be applied to existing large-scale systems, providing the means for using topological timestamping with negligible overhead.
