14. A path determining device comprising:
a non-transitory memory configured to store instructions; and
a processor coupled to the non-transitory memory, wherein the instructions cause the processor to be configured to:
determine a network connection path that passes through m reference network devices, wherein m≥1, and wherein the m reference network devices are located in a first network domain and are coupled to a device outside the network domain in which the reference network device is located;
determine a first device configuration requirement of a first network connection service for each of n reference network devices of the m reference network devices, wherein m≥n≥1;
determine whether a device configuration of each of the n reference network devices meets the first device configuration requirement, wherein the device configuration comprises a quality of service (QoS) configuration, a virtual local area network (VLAN) address, a communication protocol, or a device protection configuration; and
determine that the network connection path is a path of the first network connection service when the device configuration of each of the n reference network devices meets the first device configuration requirement.
