Patent ID: 11929915
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC G  H

Claim 9:
10. An apparatus comprising:
a non-transitory memory storage comprising instructions; and
one or more processors in communication with the memory storage, wherein the instructions, when executed by the one or more processors, cause the apparatus to:
obtain an algorithm constraint supported by each of a plurality of network devices, wherein the algorithm constraint is a constraint of a forwarding path algorithm, wherein the algorithm constraint comprises a flexible algorithm (Flex Algo);
perform network topology division on the plurality of network devices to form network topology, wherein network devices in a same network topology support a same Flex Algo, wherein each network device in the network topology has a sub-interface corresponding to the same Flex Algo; and
calculate a forwarding path between network devices in one network topology based on the same Flex Algo.
