Path Determining Method, Apparatus, Device, and System, and Computer-Readable Storage Medium

An apparatus comprising:

• one or more memories configured to store instructions;
• and
• one or more processors coupled to the one or more memories and configured to execute the instructions to cause the apparatus to:
• obtain a first path health degree of a first candidate path, wherein the first candidate path is a forwarding path from a source network element to a destination network element, wherein the first path health degree is based on network element health degrees of network elements comprised in the first candidate path and link health degrees of links comprised in the first candidate path, wherein each of the network element health degrees is based on a network element fault type and a network element fault occurrence frequency within a first monitoring periodicity, and wherein each of the link health degrees is based on a link fault type and a link fault occurrence frequency within a second monitoring periodicity;
• and
• determine a target forwarding path based on constraint information and the first path health degree,
• wherein the constraint information comprises health degree constraint information indicating a condition that a second path health degree of the target forwarding path is to meet, and
• wherein the second path health degree indicates stability of the target forwarding path.

A path determining system comprising:

• a first device configured to:
• obtain a first path health degree of a first candidate path, wherein the first candidate path is a forwarding path from a source network element to a destination network element, wherein the first path health degree is based on network element health degrees of network elements comprised in the first candidate path and link health degrees of links comprised in the first candidate path, wherein each of the network element health degrees is based on a network element fault type and a network element fault occurrence frequency within a first monitoring periodicity, and wherein each of the link health degrees is based on a link fault type and a link fault occurrence frequency within a second monitoring periodicity;
• determine a target forwarding path based on constraint information and the first path health degree, wherein the constraint information comprises health degree constraint information indicating a condition that a second path health degree of the target forwarding path is to meet, and wherein the second path health degree indicates stability of the target forwarding path;
• and
• send the target forwarding path;
• and
• a second device communicatively coupled to the first device and configured to receive the target forwarding path from the first device.
