Abstract: Various embodiments provide a fault diagnosis method and an apparatus. In those embodiments, a centralized management apparatus receives a first packet from a first network device by using a first IGP monitoring protocol session, where the first packet includes a first message sent by the first network device to a second network device. The centralized management apparatus receives a second packet from the second network device through a second IGP monitoring protocol session, where the second packet includes a second message sent by the second network device to the first network device. The centralized management apparatus performs fault diagnosis based on the first packet and the second packet.

Abstract: A method performed by an optical network controller includes: obtaining a topology structure of a subnet of a cluster, where the topology structure records an address of compute nodes in the subnet; determining a wavelength division configuration based on the topology structure, where the wavelength division configuration is used to allocate different wavelengths to the compute nodes in the subnet; providing the wavelength division configuration for the optical network switching device. Then the optical network switching device establishes an optical path between the optical network switching device and the compute node in the subnet based on the wavelength division configuration.
