How Does It Work?

  1. Four inputs are needed: (1) Time, (2) Node i, (3) Node j, (4) Transfer value
    • Transfer value can be money, passengers, or information from i to j where i & j are numbers (1, 2, …) that distinguish the nodes, whether they are people, computers, or airports.
    • These four variables will be repeated in millions and millions of records corresponding to each data transfer
  2. A window of time is defined to add up these transfers into a collection as a matrix. 
    • For example, the financial transfers done between 8:00 and 9:00am, then next, those between 9:00 and 10:00am and so on.
    • The transfers are added up into a ‘connection matrix’ for each window: Cij, for that time.
    • There are a few user adjustable parameters depending on the application. 
  3. The software processes C over time: 
    • It reduces C to a few representative values for network monitoring, and plots as a graph.
    • Entropy levels for inputs and outputs of all nodes are computed and plotted.
    • The curves are correlated over time to summarize behavior.
    • Other analysis is performed on the entropy structures
