  1. Listed processes are: travellers in transit, packets routed over the internet, users surfing the web via hyperlinks, football players passing a ball, and transactions within a payment system. The examples are organized to reflect how data can be collected (about the walk process itself or about the network over which it plays out) and that the structure of the data may or may not explicitly incorporate the integrity and bounds of the walk process
