Determining root causes of network issues

摘要

Determining root causes of network issues includes identifying a previous network issue, comparing a first behavior of network components during the previous network issue with a second behavior of the network components during a current issue of a network, and obtaining a previous user input about a previous root cause of the previous network issue collected while diagnosing the previous issue.

主权项

1. A computer program product for determining root causes of network issues, comprising:
a non-transitory computer readable storage medium, said non-transitory computer readable storage medium comprising computer readable program code embodied therewith, said computer readable program code comprising code that, when executed, causes a processor to: identify a previous network issue; compare a first behavior of network components during said previous network issue with a second behavior of said network components during a current issue of a network; obtain a previous user input about a previous root cause of said previous network issue collected while diagnosing said previous network issue, assign a similarity score to said previous network issue relating to said current issue, the similarity score defined as a scalar value that represents the similarity between the current issue and previous network issue, the scalar value is a function of similarity S defined by:
S(A1,A2)=[s,f,w]wherein Al and A2 are anomalies,wherein s is the similarity score,wherein f is a network component mapping function, and wherein w is a network component similarity strength between network issue components.
