Availability SLO-aware network optimization

A system for determining network failures, the system comprising:

• one or more memories storing key network failures;
• and
• one or more processors in communication with the one or more memories, the one or more processors configured to:
• generate a set of probabilistic failures for a network topology based at least on failure generation rules and failure rates;
• perform a risk analysis using the set of probabilistic failures to determine a failure-flow impact for each probabilistic failure in the set of probabilistic failures;
• stack rank each probabilistic failure in the set of probabilistic failures based on its respective failure-flow impact to generate a stack ranked set of probabilistic failures;
• store the key network failures in the one or more memories, wherein the key network failures are a subset of the stack ranked set of probabilistic failures;
• and
• provide the key network failures to a network planning and optimization tool based on the stack ranked set of probabilistic failures.

A non-transitory computer-readable medium storing instructions, that when executed by one or more processors, cause the one or more processors to:

• generate a set of probabilistic failures for a network topology based at least on failure generation rules and failure rates;
• perform a risk analysis using the set of probabilistic failures to determine a failure-flow impact for each probabilistic failure in the set of probabilistic failures;
• stack rank each probabilistic failure in the set of probabilistic failures based on its respective failure-flow impact to generate a stack ranked set of probabilistic failures;
• and
• provide key network failures to a network planning and optimization tool based on the stack ranked set of probabilistic failures, wherein the key network failures are a subset of the stack ranked set of probabilistic failures.
