SYSTEM AND METHOD FOR ROUTING NETWORK TRAFFIC PASSING THROUGH WEIGHTED ZONE

摘要

PROBLEM TO BE SOLVED: To provide a system and method for evaluating and selecting network paths in which the distribution of paths among different fault zones may be considered.

SOLUTION: A processor-implemented method of routing network traffic passing through fault zones comprises the steps of: identifying a path from a first network node to a second network node; identifying a set of fault zones through which the identified path passes; assigning as a zone weight the number of paths from the first network node to the second network node that include the fault zone for each fault zone in the set of fault zones; calculating a path weight for the identified path; and selecting the identified path as the current path for network traffic from the first node to the second node.
