Abstract
Systems and methods for permitted network risks in diverse route determinations introduce the concept of permitted network risks which are risks that may be present in a disjoint path calculation. This removes the binary logic in conventional shared risk path determination, i.e., either exclude or include. With the present disclosure, a network risk may be excluded (must never use) or shared (may use if needed). In an embodiment, if a route for a backup tunnel or path excluding all network risks is not possible, then a route for the backup tunnel or path may be found excluding some network risks of the primary tunnel or path except specified network risks that are determined/specified as permitted network risks. Such permitted network risks can be explicitly specified by a network operator or implicitly determined based on a category (e.g., node and/or equipment may be shared network risks whereas links may not).
