Dynamic path computation in networks based on automatically detected unavoidable risks

A method comprising steps of:

• receiving a plurality of shared risks associated with any of one or more network layers, network links, and network equipment, of a network;
• automatically creating a local ignore list for a source node and a remote ignore list for a destination node, based on unavoidable risks in the plurality of shared risks;
• and
• utilizing the plurality of shared risks in a path computation for a path between the source node and the destination node and ignoring any of the plurality of shared risks in the local ignore list and the remote ignore list.

A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to perform steps of:

• receiving a plurality of shared risks associated with any of one or more network layers, network links, and network equipment, of a network;
• automatically creating a local ignore list for a source node and a remote ignore list for a destination node, based on unavoidable risks in the plurality of shared risks;
• and
• utilizing the plurality of shared risks in a path computation for a path between the source node and the destination node and ignoring any of the plurality of shared risks in the local ignore list and the remote ignore list.

A controller comprising:

• one or more processors and memory storing instructions that, when executed, cause the one or more processors to
• receive a plurality of shared risks associated with any of one or more network layers, network links, and network equipment, of a network,
• automatically create a local ignore list for a source node and a remote ignore list for a destination node, based on unavoidable risks in the plurality of shared risks, and
• utilize the plurality of shared risks in a path computation for a path between the source node and the destination node and ignoring any of the plurality of shared risks in the local ignore list and the remote ignore list.
