Network verification method and apparatus

A network verification apparatus, comprising:

• an input/output interface configured to obtain configuration data of a plurality of network devices on a network, wherein the configuration data of the plurality of network devices is at least one of configuration data that has been configured for the network devices, configuration data that is to be configured for the network devices, and configuration data that is to be updated for the network devices, wherein a data model of the configuration data is described by using a general data modeling language independent of the network devices;
• a memory configured to store instructions;
• and
• a processor, configured to execute the instructions to:
• verify data links between the plurality of network devices based on the configuration data of the plurality of network devices and a topology structure between the plurality of network devices, wherein the processor is configured to execute the instructions to:
• calculate, based on the configuration data of the plurality of network devices and the topology structure between the plurality of network devices, a route to obtain routing forwarding entries of the plurality of network devices;
• and
• verify the data links between the plurality of network devices based on the routing forwarding entries of the plurality of network devices.

A network system comprising a network verification system and plurality of network devices, the network verification system is configured to:

• obtain configuration data of a plurality of network devices, wherein the configuration data of the plurality of network devices is at least one of configuration data that has been configured for the network devices, configuration data that is to be configured for the network devices, and configuration data that is to be updated for the network devices, wherein a data model of the configuration data is described by using a general data modeling language independent of the network devices;
• and
• verify data links between the plurality of network devices based on the configuration data of the plurality of network devices and a topology structure between the plurality of network devices by:
• calculating, based on the configuration data of the plurality of network devices and the topology structure between the plurality of network devices, a route to obtain routing forwarding entries of the plurality of network devices;
• and
• verifying the data links between the plurality of network devices based on the routing forwarding entries of the plurality of network devices.
