Autonomous diagnosis and mitigation of network anomalies

A network management device, comprising:

• a processor;
• and
• memory communicatively coupled to said processor;
• wherein said memory comprises computer-executable code embodied therewith, said computer-executable code being configured to cause said processor to implement:
• a parameter monitoring module configured to monitor parameters of interest set by a network administrator from a plurality of network devices communicatively coupled to said network management device;
• a sketching module configured to hash said monitored parameters of interest;
• a principal components analysis (PCA) engine module configured to perform principal components analysis on computed entropy values of said hashed monitored parameters of interest to detect a network anomaly in real time;
• and
• an anomaly resolution module configured to autonomously identify a source of said network anomaly and take action to mitigate said anomaly.

A computer program product for identifying and mitigating network anomalies, said computer program product comprising:

• a non-transitory, computer usable medium having computer usable program code embodied therewith, said computer usable program code comprising:
• computer usable program code configured to cause a computer to create a plurality of sketch matrices wherein each said sketch matrix corresponds to an individual hashing function and each row in said sketch matrix corresponds to an array of hashed parameters of interest from a plurality of network devices for a given period of time, said parameters of interest being configurable by an administrator;
• computer usable program code configured to cause said computer to create a principal components analysis (PCA) input matrix for each of said sketch matrices by computing an entropy value for each element in said sketch matrices;
• and
• computer usable program code configured to cause said computer to perform principal components analysis (PCA) on each of said PCA input matrices to heuristically detect a network anomaly in real time.
