Abstract: This application provides network device capacity expansion methods and devices. One method includes: obtaining network performance data of a target network device, determining a state of the target network device based on the network performance data of the target network device, and determining, based on the state of the target network device, whether to perform capacity expansion for the target network device. In the foregoing technical solution, whether a capacity expansion operation needs to be performed on a network device can be determined in a timely manner based on a state of the network device.

Abstract: Embodiments of the present invention provide a delay measurement method and device. The method includes: determining a first delay of a first path; obtaining a first two-way delay of a first two-way path; obtaining a first one-way delay from a third IGW port to a provider/provider edge device; obtaining a second one-way delay from the provider/provider edge device to a first IGW port; determining a second delay, where the second delay is obtained by subtracting the first one-way delay and the second one-way delay from the first two-way delay; and comparing the first delay with the second delay. By means of the foregoing solutions, a one-way delay relationship between delays from the OTT server to different IGWs may be effectively determined, so as to determine a path whose one-way delay is optimal according to the one-way delay relationship.
