Methods and Systems for Determining Entropy Metrics for Networks

A system for network analysis comprising:

• at least two network nodes;
• a network interface in communication with the at least two network nodes;
• a processor coupled to the network interface, the processor configured for performing the steps of:
• receiving network data;
• constructing a C(i, j) matrix comprising a Cc matrix and a Cr matrix;
• normalizing the C(i, j) matrix;
• constructing a Mc and Mr matrix each having at least one row and at least one column;
• determining entropy values for each row and column of the Mc and Mr matrices;
• and
• plotting a spectral curve base on the determined entropy values, wherein the spectral curve indicates network behavior.

A method for network monitoring comprising:

• determining a normal network topology profile for a network based on entropy spectra;
• determining a current network topology profile for a network based on entropy spectra;
• determining a variance between the normal network topology profile and the current network topology profile;
• and
• displaying the determined variance wherein the variance is indicative of abnormal network activity.
