Automatic discovery of relationships across multiple network layers
Andrew Turner, Hyong S. Kim, Tina H. Wong · 2007
As networks become increasingly large and complex the relationships and dependencies between network elements also grow in complexity and size. If an e-mail server goes off-line for ten minutes but never goes off-line again, it might not be a serious problem, and can be forgotten about. But if the e-mail server repeatedly goes off-line, the cause of the problem must be found. The difficulty for network operators is discovering what causes the problem -- we address this issue and formalize a method to make event logs more useful to network operators.
